Antique postcard shows rocks scarred by glacial erosion Yosemite Valley from an airplane, showing the "U" shape Glacially plucked granitic bedrock near Mariehamn, Åland Islands Kamenitsa Peak erosion in Pirin mountain, Bulgaria Glacial landforms are landforms created by the action of glaciers. Most of today's glacial landforms were created by the movement of large ice sheets during the Quaternary glaciations. Some areas, like Fennoscandia and the southern Andes, have extensive occurrences of glacial landforms; other areas, such as the Sahara, display rare and very old fossil glacial landforms.

Physiographic regions of the world are a means of defining Earth's landforms into distinct regions, based upon the classic three-tiered approach by Nevin M. Fenneman in 1916, that separates landforms into physiographic divisions, physiographic provinces, and physiographic sections. The model became the basis for similar classifications of other continents, and is still considered valid .

Studying glacial motion and the landforms that result requires tools from many different disciplines: physical geography, climatology, and geology are among the areas sometime grouped together and called earth science. During the Pleistocene (the last ice age), huge sheets of ice called continental glaciers advanced over much of the earth. The movement of these continental glaciers created many now-familiar glacial landforms. As the glaciers were expanded, due to their accumulating weight of snow and ice, they crushed and redistributed surface rocks, creating erosional landforms such as striations, cirques, and hanging valleys.

In a classic map of the world (with north at the top), the southern ends of the continental landmasses appear to "drip" downward. Continental drip is the observation that southward-pointing landforms are more numerous and prominent than northward-pointing landforms. For example, Africa, South America, India etc. all taper off to a point towards the south.

Erosional landforms grow when more sediment is removed from an area faster than it is deposited. They are widespread in hardened, wind-swept snow surfaces, such as the Antarctic Plateau: see sastrugi. In sand and rock, they are rarely preserved except in arid regions. Outside of arid regions, moving water - which is heavier and more erosive than wind - erases aeolian landforms.

Danxia landform is formed from red-coloured sandstones and conglomerates of largely Cretaceous age. The landforms look very much like karst topography that forms in areas underlain by limestones, but since the rocks that form danxia are sandstones and conglomerates, they have been called "pseudo-karst" landforms. They were formed by endogenous forces (including uplift) and exogenous forces (including weathering and erosion).

If the Hin Namno, bordering Phong Nha on the west (in Laotian territory) was to be combined with the national park in a continuous reserve, the combined reserve would be the largest surviving karst forest in southeastern Asia (317,754 ha). In general, there are two groups of landforms in the Phong Nha-Kẻ Bàng area, namely non-karstic and karstic landforms. Non- karstic landforms includes three types: The middle and low dome-block mountains developed in intrusive magmatic massifs; The middle denudation- structural mountain belts developed in terrigenous rocks of Cretaceous age; and The low block-denudational mountain belts developed in other terrigenous rocks. Karstic landforms in this area are of typical tropical karst which are divided into two groups of forms: The karstic forms on the surface including cone and tower karst, karrens, valleys and dolines, border polje, etc.

This work describes landforms such as karren, dolines and poljes. In a 1918 publication, Cvijić proposed a cyclical model for karstic landscape development. The results of this work written in French were made accessible to English-language scientists in 1921 when it was commented by E.M. Sanders. Differences in climate and geology were used by Cvijić to explain various shapes and types of karst landforms, sometimes incorrectly.

Drumlins may comprise layers of clay, silt, sand, gravel and boulders in various proportions; perhaps indicating that material was repeatedly added to a core, which may be of rock or glacial till. Alternatively, drumlins may be residual, with the landforms resulting from erosion of material between the landforms. The dilatancy of glacial till was invoked as a major factor in drumlin formation.Smalley, I.J., Unwin, D.J. 1968.

Davis had studied geology under Nathaniel S. Shaler at Harvard in the 1870s, and was offered a teaching position there in 1878. In 1894 he published Elementary Meteorology, a textbook that was the first to unite and organize a previously uncoordinated body of knowledge in that field. Davis' most profound contribution to scientific knowledge came in his publication in 1912 of a treatise entitled A Reasoned Description of Landforms, in which he provided a template for outlining the genesis, development, and classification of landforms on a global scale. In later publications he described the erosion cycle and other important concepts in understanding the development and lifecycle of landforms.

The scientific study of landforms is known as geomorphology. In onomastic terminology, toponyms (geographical proper names) of individual landform objects (mountains, hills, valleys, etc.) are called oronyms.
|
|
Depositional landforms grow when sediment is deposited into an area faster than it is removed. These bedforms grow from snow during blizzards, or from sand and dust in areas where wind patterns trap particles. For example, the Great Sand Dunes in Colorado grow as sand blown from a wide plain is deposited against the edge of the Sangre de Cristo mountains. Depositional landforms include dunes, barchan dunes, ripple marks, and loess.
|
|
A landform comprises a geomorphological unit and is largely defined by its surface form and location in the landscape, as part of the terrain, and as such is typically an element of topography. Landforms are categorized by features such as elevation, slope, orientation, stratification, rock exposure, and soil type. They include berms, mounds, hills, cliffs, valleys, rivers, and numerous other elements. Oceans and continents are the highest-order landforms.
|
|
These are areas with relatively homogeneous morphometric properties, bounded by lines of discontinuity. A plateau or a hill can be observed at various scales ranging from few hundred meters to hundreds of kilometers. Hence, the spatial distribution of landforms is often scale-dependent as is the case for soils and geological strata. A number of factors, ranging from plate tectonics to erosion and deposition, can generate and affect landforms.

Hydrogeomorphology has been defined as “an interdisciplinary science that focuses on the interaction and linkage of hydrologic processes with landforms or earth materials and the interaction of geomorphic processes with surface and subsurface water in temporal and spatial dimensions.” The term 'hydro- geomorphology’ designates the study of landforms caused by the action of water. By this definition hydro-geomorphology is inseparable part of geomorphology moreover fluvial geomorphology, because water is one of the most important agents in forming and shaping of landforms. From the groundwater point of view integration of geological, structural and hydrological data with hydro-geomorphologic data is very much useful in finding out the groundwater potential zones with fruitful results.

The Eramosa flows through an area covered with over 200 glacial potholes near Rockwood. One of the largest of these is the Devil's Well, which measures wide at the top and at its base; and deep. The glacial landforms are contained within Rockwood Conservation Area, where the bluffs measure deep and wide. All of these landforms were created by the recession of the Laurentide Ice Sheet at the end of the Wisconsin glaciation.

The glacial origin of some landforms has been questioned. Erling Lindström has advanced the thesis that roches moutonnées may not be entirely glacial landforms taking most of their shape before glaciation. Jointing that contribute to the shape typically predate glaciation and roche moutonnée-like forms can be found in tropical areas such as East Africa and Australia. Further at Ivö Lake in Sweden weathered rock surfaces exposed by kaolin mining resemble roche moutonnée.

They are referred to by some authors as ring-mound landforms (RMLs). Because the distribution of these landforms are coterminous with this floor unit, they are thought to be indicative of the surface processes that formed the valley system. At least two different sets of these cones exist in the Athabasca Valles, in which some have wakes and others do not. Some researchers have proposed that the cones with wakes formed chronologically earlier than those without wakes.

According to a second principle of classification, a concordant coastline is a coastline where bands of different rock types run parallel to the shore. These rock types are usually of varying resistance, so the coastline forms distinctive landforms, such as coves. Discordant coastlines feature distinctive landforms because the rocks are eroded by ocean waves. The less resistant rocks erode faster, creating inlets or bay; the more resistant rocks erode more slowly, remaining as headlands or outcroppings.

They were formed by endogenous forces (including uplift) and exogenous forces (including weathering and erosion).China Danxia The first studies on what are now referred to as Danxia landforms were conducted at Mount Danxia near Shaoguan, China. In the 1920s and 1930s Chinese geologists made an effort to learn more about these interesting geomorphic structures. Danxia landforms are made up of uplifted continental crust that has been faulted and eroded, exposing large scarps of layered rock, red in color.

Jencks believed that contemporary science is potentially a great moving force for creativity, because it tells us the truth about the way the universe is and shows us the patterns of beauty. As explained in his book The Universe in the Landscape (2011), his work is content-driven. His many landforms are based on the idea that landforming is a radical hybrid activity combining gardens, landscape, urbanism, architecture, sculpture, and epigraphy. Thus, the landforms often include enigmatic writing and complex symbolism.

Even after the mining industry had ceased in 1979, the village still bore the scars of its extensive mining history. Enormous landforms created by the dumping of tailings from the colliery (known locally as “coal tips” or simply “tips”) still remained. These landforms were levelled and landscaped during the 1980s, now very little traces remain of the mining industry in the village. More recently, plans to produce environmentally friendly geothermically heated water at around 20.6 degrees Celsius for use in heating homes.

Barrier island contrasted with other coastal landforms. Barrier islands are coastal landforms and a type of dune system that are exceptionally flat or lumpy areas of sand that form by wave and tidal action parallel to the mainland coast. They usually occur in chains, consisting of anything from a few islands to more than a dozen. They are subject to change during storms and other action, but absorb energy and protect the coastlines and create areas of protected waters where wetlands may flourish.

In Germany, Oscar Peschel in 1870, proposed that geographers should study the morphology of the Earth's surface, having an interest in the study of landforms for the development of human beings. As the chair of geography (and a geologist by training) in Bonn, Germany, Ferdinand von Richthofen made the study of landforms the main research field for himself and his students. Elsewhere, Thomas Henry Huxley's Physiography was published in 1877 in Britain. Shortly after, the field of "physical geography" itself was renamed as "physiography".

This conical hill in Salar de Arizaro, Salta, Argentina called Cono de Arita constitutes a landform. A landform is a natural or artificial feature of the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Typical landforms include hills, mountains, plateaus, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins.

Traditional terrestrial soil mapping is conducted by a soil scientist trained to understand the interaction of soil- forming processes and soil-landscape relations. Mapping soils involves field work traversing the landscape and digging many holes to observe and classify the soil in various locations. Subaqueous soil mapping is performed in much the same way, except the mapper is in water. Instead of topographic maps and aerial photographs, subaqueous soil mapping uses bathymetric maps to identify underwater landscapes and landforms (a glossary of subaqueous landforms is available at: Glossary of Subaqueous Soil Landscape Terms).

According to one principle of classification, an emergent coastline is a coastline which has experienced a fall in sea level, because of either a global sea level change, or local uplift. Emergent coastlines are identifiable by the coastal landforms, which are above the high tide mark, such as raised beaches. In contrast, a submergent coastline is one where the sea level has risen, due to a global sea level change, local subsidence, or isostatic rebound. Submergent coastlines are identifiable by their submerged, or "drowned" landforms, such as rias (drowned valleys) and fjords.

Once sediment transport begins, it continues via gravity and momentum: particles that fall out of the air typically impact the surface with enough force to dislodge further particles (called reptation). These impacts are separated in space by the saltation hop length of the traveling particles, which creates distinct areas of erosion and/or deposition. As time passes, the surface rises in areas with net deposition, and lowers in areas with net erosion, creating initial landforms. Larger aeolian landforms alter the surface wind field in patterns that promote their growth.

Frost boils often occur in groups, and may form terraces if a series of them occur on a slope. On slopes, frost boils are sometimes protected from erosion by a thin layer of mosses and lichens which retains moisture through surface tension as sediments flow downslope to form a lobe. These landforms eventually settle like a caterpillar track. Common characteristics of landforms created by frost boils include a bowl-shaped boil, an elevated center, a formation of an organic layer on the outer edge, and resistance of the soil surface to vegetation colonization.

West-east-trending valleys score the Phlegra Montes region with a strike that is coincident with the orientation of graben to the west of the mountains, suggesting that regional extensional tectonism affected this region of Mars. Graben along this trend are also present in Galaxias Chaos and into Utopia Planitia. In the Phlegra Montes, some of these graben have been interpreted to host glaciers that have since given way to flow-like landforms called lineated valley fills (LVF). This is not considered a typical way for such landforms to occur on Mars.

In an article published in late 2017, the scientists concluded that Hunga Tonga-Hunga Haapai has eroded in ways that are remarkably similar to the erosion patterns seen on similar landforms on Mars. The scientists noted that this suggests Mars was once flooded briefly by water, but that the water receded fairly quickly. Further study of the similarities between Hunga Tonga-Hunga Haapai and Martian volcanic landforms is needed, they said. In October 2018, scientists visited the island and discovered that its surface is covered with gravel, sticky mud, and vegetation.

For the most part the Southern Rim is the farthest from Nashville, rising at some points just a few miles north of the border with Alabama. The landforms are continuous with those in adjacent portions of Alabama, although perhaps the most spectacular landforms of any portion of the Rim are to be found there. The stratigraphy of the Southern Highland Rim is primarily composed of flat-lying limestones, dolomites, and shales, and to a much lesser extent, of cherts, siltstones, mudstones, and very fine grained to conglomeratic sandstones.

Apart from volcanism, aeolian processes and water erosion were active in Meidob, producing widespread sedimentary covers especially at the margins of the field. A number of wadis extend radially away from the centre of the Meidob volcanic field and carry water during flash floods, transporting sediment and floating pumice. Winds transport sediments onto old lava flows and volcanic landforms, but owing to its youth many landforms of the Midob volcanic field are little eroded. During the early and middle Holocene a number of craters contained lakes; some of these have left diatomite sediments and were populated by ostracods living in freshwater.

Its distinguishing feature is the marriage of landforms, substrates, and vegetation throughout all phases of design and construction, which previously have been kept as separate disciplines. Though landscape engineering embodies all elements of traditional engineering (planning, investigation, design, construction, operation, assessment, research, management, and training), it is focused on three main areas. The first is closure planning – which includes goal setting and design of the landscape as a whole. The second division is landscape design more focused on the design of individual landforms to reliably meet the goals as set out in the closure planning process.

El Capitan Almost all of the landforms in the Yosemite area are cut from the granitic rock of the Sierra Nevada Batholith (a batholith is a large mass of intrusive igneous rock that formed deep below the surface). About 5% of the park's landforms (mostly in its eastern margin near Mount Dana) are metamorphosed volcanic and sedimentary rocks. These rocks are called roof pendants because they were once the roof of the underlying granitic rock. Erosion acting upon different types of uplift- created joint and fracture systems is responsible for creating the valleys, canyons, domes, and other features we see today.

Mozart Ice Piedmont () is an ice piedmont, 60 nautical miles (110 km) long- running in a NW-SE direction and 15 nautical miles (28 km) wide in its widest part, on the west coast of Alexander Island, Antarctica. Mapped from air photos taken by the Ronne Antarctic Research Expedition (RARE) in 1947, by Searle of the Falkland Islands Dependencies Survey (FIDS) in 1960. Named by the United Kingdom Antarctic Place-Names Committee (UK-APC) for Wolfgang Amadeus Mozart (1756–1791), famous Austrian composer. Some landforms within this area are named in association with the Mozart Ice Piedmont such as Figaro Nunatak, along with a few other landforms.

Glacial landforms dominate Banff's geomorphology, with examples of all classic glacial forms, including cirques, arêtes, hanging valleys, moraines, and U-shaped valleys. The pre-existing structure left over from mountain-building strongly guided glacial erosion: mountains in Banff include complex, irregular, anticlinal, synclinal, castellate, dogtooth, and sawback mountains. Many of the mountain ranges trend northwest to southeast, with sedimentary layering dipping down to the west at 40–60 degrees. This leads to dip slope landforms, with generally steeper east and north faces, and trellis drainage, where rivers and old glacial valleys followed the weaker layers in the rocks as they were relatively easily weathered and eroded.

For example, serpentinite is a kind of rock formed in a process called serpentinization, in which a host mineral produces a pseudomorph, and the original mineral is eventually replaced and/or destroyed, but is still present until the process is complete. Within geomorphology a relict landform is a landform that took form from geomorphic processes that are not active at present. In a Scandinavian context, this is often meant to imply that relict landforms were formed before the last glaciation and survived it under cold- based parts of the ice sheet. Climatic geomorphologist Julius Büdel estimated that 95% of mid-latitude landforms are relict.

Because of the prevalence of this method for identifying and mapping riffles, riffles are often thought of as part of a paired sequence, alternating with pools- the lows between the riffles. However, modern topographic maps of rivers with meter-scale resolution reveal that rivers exhibit a diversity of in-channel landforms. For a long time, scientists have observed that, all other things being equal, riffles tend to be substantially wider than other in-channel landforms, but only recently has there been high enough quality of river maps to confirm that this is true. The physics mechanism that explains why this happens is called flow convergence routing.

Geomorphology is the scientific study of landforms and the processes that shape them. In terms of analogue sites, scientists search for locations on Earth that exhibit similar landforms such as can be found on exploration targets like the Moon, Mars or even asteroids and comets. The idea is to confront astronauts, robots or scientific equipment with sites that resemble in their geologic appearance those extraterrestrial surfaces. Examples are volcanic sites which resemble lunar terrain (regolith), polar locations and glaciers that can be compared to the poles of Mars or of Jupiter moon Europa, or terrestrial lava tubes which can also be found on the Moon or Mars.

El Capitan, a granite monolith on Yosemite Valley's northern escarpment Almost all of the landforms in the Yosemite area are cut from the granitic rock of the Sierra Nevada Batholith (a batholith is a large mass of intrusive igneous rock that formed deep below the surface). About 5% of the park's landforms (mostly in its eastern margin near Mount Dana) are metamorphosed volcanic and sedimentary rocks. These rocks are called roof pendants because they were once the roof of the underlying granitic rock. Erosion acting upon different types of uplift-created joint and fracture systems is responsible for creating the valleys, canyons, domes, and other features we see today.

It then extends southeast into northern Bolivia and in a narrow band south along the base of the Andes Mountains. Elevations range from in the west to on the eastern edge of the region. Landforms present in this region include the upland terra firme (non-flooded) mostly on nutrient-poor lateritic soils, ancient alluvial plains (mostly non-flooded) on nutrient-rich soils, and present alluvial plains (várzea, seasonally flooded) of super-rich sediments renewed with each annual flood. Floristically, distinct lowland humid forest types occur on each of these landforms with the terra firme mature forests and late successional, seasonally flooded forest being the two major types.

In current usage, physiography still lends itself to confusion as to which meaning is meant, the more specialized "geomorphological" definition or the more encompassing "physical geography" definition. For the remainder of this article, emphasis will remain on the more "geomorphological" usage, which is based upon geological landforms, not on climate, vegetation, or other non-geological criteria. For the purposes of physiographic mapping, landforms are classified according to both their geologic structures and histories. Distinctions based on geologic age also correspond to physiographic distinctions where the forms are so recent as to be in their first erosion cycle, as is generally the case with sheets of glacial drift.
|
|
Biological factors can also influence landforms— for example, note the role of vegetation in the development of dune systems and salt marshes, and the work of corals and algae in the formation of coral reefs. Landforms do not include man-made features, such as canals, ports and many harbors; and geographic features, such as deserts, forests, and grasslands. Many of the terms are not restricted to refer to features of the planet Earth, and can be used to describe surface features of other planets and similar objects in the Universe. Examples are mountains, hills, polar caps, and valleys, which are found on all of the terrestrial planets.

The Iowan Surface ecoregion is a geologically complex region located between the bedrock-dominated landforms of the Paleozic Plateau/Coulee Section (52b) and the relatively recent glacial drift landforms of the Des Moines Lobe (47b). The southern and southeastern border of this region is irregular and crossed by major northwest- to southeast-trending stream valleys. In the northern portion of the region, the glacial deposits are thin, and shallow limestone bedrock creates karst features such as sinkholes and sags. There are no natural lakes of glacial origin in this region, but overflow areas and backwater ponds occur on some of the larger river channels contributing to some diversity of aquatic habitat and a large number of fish species.

A landscape is the visible features of an area of land, its landforms, and how they integrate with natural or man-made features.New Oxford American Dictionary. A landscape includes the physical elements of geophysically defined landforms such as (ice-capped) mountains, hills, water bodies such as rivers, lakes, ponds and the sea, living elements of land cover including indigenous vegetation, human elements including different forms of land use, buildings, and structures, and transitory elements such as lighting and weather conditions. Combining both their physical origins and the cultural overlay of human presence, often created over millennia, landscapes reflect a living synthesis of people and place that is vital to local and national identity.

A joint initiative between the City of Toronto and the Toronto Region Conservation Authority (TRCA), the landform project involves the construction of new landforms south of the plant in Ashbridges Bay using the material removed from the DR&CW; tunnelling projects. The new landforms will provide improved sediment and erosion control in Ashbridges Bay, improving boat access and eliminating the need for regular dredging of the Coatsworth Cut area of the bay. Part of the reclaimed lands will also be the site of a new high-rate treatment facility, designed specifically to treat wastewater intercepted from combined sewers by the DR&CW; tunnels. Construction began in 2019 and is expected to conclude in 2025.

Pearson Island was formed along with the rest of the Pearson Isles about 10,500 years ago following the rise of sea levels at the start of the Holocene.Robinson et al, 1996, Page 11 Geologically, Pearson Island and the other members of the Pearson Isles are the summits of an inselberg partially concealed by sea level rise. Pearson Island exhibits landforms caused firstly by the formation of the inselberg and the characteristics of the granite from which it formed and secondly by the erosive and formative processes associated with the sea.RSSA, 1971, page 123 Firstly, landforms associated with the formation of the inselberg and with its constituent material respectively are sheet structures and orthogonal jointing.

In addition, the name Book Cliffs is often applied to both landforms, with Roan Cliffs being an alternate name. Moreover, because of the how far they are spread between Utah and Colorado, they are sometimes mistakenly believed to be separate landforms of the same name within each state. The Roan Cliffs are situated north of (in back of) and above, but run roughly parallel to, the Book Cliffs. Stretching nearly from west to east, the Roan Cliffs begin on southern edge of the West Tavaputs Plateau, on the eastern edge of the Willow Creek (and the US‑191 corridor), north of Emma Park, and northwest of Helper on the Carbon‑Duchesne county line.

These landforms were deposited near the end of a sea level high stand, when sea level was just beginning to fall, otherwise they would have been reworked subsequently by stable or rising seas. Some chevrons contain multiple smaller ridges “nested” in a seaward direction (Hearty et al., 1998), providing further evidence that sea level was falling fast enough to strand and preserve older chevrons as distinct landforms. Older ridges adjacent to the chevron ridges have wave runup deposits that reach heights nearly 40 m above present sea level, far above the reach of a quiescent 5e sea surface. Such elevated beach fenestrae are considered to result from runup of very large waves (Wanless and Dravis, 1989).

Blue ice is found in some areas. Glacial activity has altered the volcano, generating glacial striae and roches moutonnees on the older volcanic rocks and frost shattering landforms and solifluction ridges. Glacial drift lies on the ice-free southwestern flank. In turn, glacial moraines have been overrun by lava flows.

Landforms (mountains, hills, ridges, lakes, valleys, etc.) are sometimes formed when the faults have a large vertical displacement. Adjacent raised blocks (horsts) and down-dropped blocks (grabens) can form high escarpments. Often the movement of these blocks is accompanied by tilting, due to compaction or stretching of the crust at that point.

Apart from the landforms left behind by glaciers, glaciers themselves may be striking features of the terrain, particularly in the polar regions of Earth. Notable examples include valley glaciers where glacial flow is restricted by the valley walls, crevasses in the upper section of glacial ice, and icefalls—the ice equivalent of waterfalls.

The Athabasca Valles are the youngest of the outflow channel systems on Mars, and has historically been understood to have formed as the result of megaflooding. Distinctive streamlined teardrop-shaped landforms, branching channels, and transverse ripple dunes (interpreted to have formed under water) are all found within the valley system, and are morphologically similar to those found in the Channeled Scablands on Earth in eastern Washington state. The Channeled Scablands were formed during the catastrophic Missoula Floods, a series of megafloods sourced from sudden breaches in ice dams buttressing the Pleistocene-aged glacial Lake Missoula. According to this interpretation, these streamlined landforms were created when passing floodwaters deposited sediment against protruding bedrock outcroppings, such as crater rims or bedrock mesas.

The Little Blue Lake is one of a number of similar landforms occurring in the area to the south of the dormant volcano in Mount Gambier including the area around the dormant volcano at Mount Schank. These cenotes are similar in form as they all have collapse dolines with circular plans, cliffs, lakes filled to the water table, large rubble cones on their floors and clustered together in several groups along in the flat coastal plain composed of a Miocene limestone known as Gambier Limestone. These cenotes differ from other karst landforms in the south east of South Australia by their relative depth (i.e. as deep as in one cenote), the absence of any underwater phreatic passages and a different water chemistry.

Later shorter glaciers reoccupied the same valleys; outwash gravel deposits are found downstream below the moraines, such as below the Chalchala and Pocolli valleys on the southern flank of the volcano where most glacial landforms are found. Glacial landforms include glacial striae and ice drift deposits are found on the volcano, as are several extensive moraine systems. Three separate stages of glaciation have been inferred at Tunupa, one dating proposal dates the first advance to about 160,000 before present, the second lasts until about 15,000 years before present and the last one occurred during the Younger Dryas. The southern slopes of Tunupa are incised by the shorelines of former lakes that occupied the Altiplano, such as Lake Minchin and Lake Tauca.

MOC aboard MGS The HiRISE camera is designed to view surface features of Mars in greater detail than has previously been possible. It has provided a closer look at fresh martian craters, revealing alluvial fans, viscous flow features and ponded regions of pitted materials containing breccia clast. This allows for the study of the age of Martian features, looking for landing sites for future Mars landers, and in general, seeing the Martian surface in far greater detail than has previously been done from orbit. By doing so, it is allowing better studies of Martian channels and valleys, volcanic landforms, possible former lakes and oceans, sand dune fields such as Hagal and Nili Patera, and other surface landforms as they exist on the Martian surface.

Nubbins form in a similar way to castle koppies and bornhardts and the three landforms can be seen as different expressions of the same phenomena. Nubbins occur often in patterned groups. Nubbins can be found in humid tropical and monsoon climate areas. According to geomorphologist C.R. Twidale this is the environment where most nubbins form.

Certain regions of Mars display scalloped-shaped depressions. The depressions are suspected to be the remains of a degrading ice-rich mantle deposit. Scallops are caused by ice sublimating from frozen soil. The landforms of scalloped topography can be formed by the subsurface loss of water ice by sublimation under current Martian climate conditions.

Sometimes chunks of ice fall from the glacier and get buried in the land surface. When they melt, a more or less round hole remains. Many of these "kettle holes" have been identified on Mars. Despite strong evidence for glacial flow on Mars, there is little convincing evidence for landforms carved by glacial erosion, e.g.

At its largest, it rose to above sea level. Eventually the water found a low divide near New Martinsville, West Virginia, creating an outlet to the south and west into the Teays River. Thus, the upper Ohio network of river valleys came into form. Once Lake Monongahela formed, the water drowned the existing landforms.

Within climatic geomorphology one approach is to study relict landforms to infer ancient climates. Being often concerned about past climates climatic geomorphology is considered sometimes to be a theme of historical geology. Climatic geomorphology is of limited use to study recent (Quaternary, Holocene) large climate changes since there are seldom discernible in the geomorphological record.

Mountain ranges are usually segmented by highlands or mountain passes and valleys. Individual mountains within the same mountain range do not necessarily have the same geologic structure or petrology. They may be a mix of different orogenic expressions and terranes, for example thrust sheets, uplifted blocks, fold mountains, and volcanic landforms resulting in a variety of rock types.

Transitions between beach states are often caused by changes in wave energy, with storms causing reflective beach profiles to flatten (offshore movement of sediment under steeper waves), thus adopting a more dissipative profile. Morphodynamic processes are also associated with other coastal landforms, for example spur and groove formation topography on coral reefs and tidal flats in infilling estuaries.

Some deposits are friable, others well cemented. Locally, there appears to be three prominent layers of sandstone separated by mudstone. Because of variable erosion rates, each influences topography by forming ledges and benches, and in places may form mesa-like landforms. In and around the city, these occur roughly at 960, 1000, and 1060 feet above sea level.

Planet Heights () is a series of summits running along an ice-free ridge, extending 24 nautical miles (44 km) in a north-south direction between the southernmost extremity of the LeMay Range and George VI Sound in the east part of Alexander Island, Antarctica. Many landforms and nearby features are named in association with this mountain range; some of these include landforms named after astronomers, satellites, planets and other things related to astrology and astrophysics. The mountain range was first mapped from air photos taken by the Ronne Antarctic Research Expedition (RARE), 1947–48, by Searle of the Falkland Islands Dependencies Survey (FIDS) in 1960. Named by the United Kingdom Antarctic Place-Names Committee (UK-APC) from association with the nearby glaciers named for planets of the solar system.

In 1953, Schaefer defined the Biber glaciation (), Biber Glacial (Biber-Glazial), or Biber Ice Age (Biber-Eiszeit) from gravel landforms of the Stauden Plateau in the area of the Iller-Lech Plateau and in the Aindling terrace sequence, by grouping together the so- called Middle and Upper Cover Gravels or Deckenschotter. This corresponded to the Staufenberg Gravel Terrace on the Iller-Lech Plateau, identified in 1974 by Scheunenpflug, and the so-called High Gravels (Hochschottern) of the Aindling region. The rich crystalline sedimentary facies (Kristallinreiche Liegendfazies), that Löscher distinguished in 1976 in the area of the Rhine Glacier of the western Riß-Iller Plateau may also be paralleled with these glacial landforms. The gravels in the Iller-Lech region ascribed to the Biber glaciation are generally heavily weathered and originate from the Northern Limestone Alps.

The Pearson Isles were formed about 10,500 years ago following the rise of sea levels at the start of the Holocene.Robinson et al, 1996, Page 11 The four members of the Pearson Isles are the peaks of an inselberg remaining after its gradual concealment by sea level rise. The inselberg is composed of a basement rock granite belonging to a group of rocks associated with an event known as the Hiltaba Suite which is a series of volcanic events occurring about 1,590 million years ago within the area now covered in part by the western Eyre Peninsula, the adjacent interior of the Australian continent and the part of the Great Australian Bight immediately adjoining the western coast of Eyre Peninsula. Landforms on each of the islands are dominated firstly by the granite basement rock and its jointing, and secondly by rock and erosive processes associated with the marine environment. The former class of landforms include “massive curvilinear sheets” on the lower level of the islands and boulders “derived from the breakdown of the sheets” on the upper levels of the islands. The second class of landforms included “remnants of aeolianite-old coastal foredune deposits” associated with a time when the sea level was lowered.

An asymmetric valley is a valley that has steeper slopes on one side. Asymmetric valleys are azonal landforms. In high altitudes south-facing slopes are usually steeper than north-facing slopes. Large incised rivers crossing strike-slip faults can form asymmetrical valleys, as one bank of the river might be continuously being renewed while the other bank drifts away from the stationary river.

Mojave has alluvial fans that look remarkably similar to landforms in the Mojave Desert in the American southwest. Fans inside and around the outsides of the crater are closely similar to Earth's alluvial fans. As on Earth, the largest rocks are near the mouths of the fans. Because the channels start at ridge tops, it is believed they were formed by heavy downpours.

A gas hydrate pingo (GHP) is a submarine dome structure formed by the accumulation gas hydrates under the seafloor. Gas hydrate pingos resemble the pingo landforms found on land in periglacial regions. Gas hydrate pingo may accumulate non-hydrate gas under pressure leading to explosions that forms craters. Crater depressions of this type have been found on the seafloor of Barents Sea.

In almost all mountain regions of the world, conical peaks may be formed by erosion processes, but they are not usually isolated landforms. Often they arise through the formation of ordinary riverine meanders. But they can also result from the action of an entrenched river that has cut deeply into a plateau. The resulting cutoff meander spur may be cone-shaped.

These various interactions generate a wide variety of beaches. (see Beach). Other than the interactions between coastal land forms and physical processes there is also the addition of modification of these landforms through anthropogenic sources (see human modifications). Some of the anthropogenic sources of modification have been put in place to halt erosion or prevent harbors from filling up with sediment.

Unfortunately, the medieval castle was destroyed in the nineteenth century because of an explosion in the ammunition depot of the castle. The mountain rock is granite, which also the historic and present village is built upon in a fusion of nature and its landforms. This fusion can be seen in the uses of caves and rocks being converted into construction parts.

When these channel switching events happen repeatedly over time, a mature delta will gain a distributary network.Easterbrook, Don J.Surface Processes and Landforms Second EditionPrentice Hall, New Jersey: 1999. Subsidence of the delta and/or sea- level rise can further cause backwater and deposition in the delta. This deposition fills the channels and leaves a geologic record of channel avulsion in sedimentary basins.

The sediment that is submerged during rough weather forms landforms including storm bars. In calmer weather waves return sediment to the visible part of the beach. Due to longshore drift some sediment can end up further along the beach from where it started. Often coastal areas have developed sustainable coastal positions where the sediment moving off beaches is sustainable submersion.

Conservation of these sites usually concentrates on maintenance of access for future study. Deposit sites are features which are limited in extent or physically delicate—for example, they include small lenses of sediment, mine tailings, caves and other landforms. If such features become damaged they cannot be recreated, and conservation usually involves protecting the feature from erosion or other damage.

Streams going through the bioregion are intensely rooted with only a few terrace geographies, and valleys are really narrow. The landforms that are seen today are due to the lengthy, constant progressions of movement and erosion over millions of years, which escalate into a variation of landscapes across Australia. These are continuing to experience modification as the continent moves north.

Another rifting event established the Mayilashan ocean basin and back-arc basin in east Junggar during Silurian. However, the compressional environment restricted the two landforms so that they ended up shut and folded in the late Silurian. This eventually led to the convergence of Tarim, Kazakhstan and Siberian paleo-plates. They were from the original Xinjiang paleocraton that puzzled each other again.

Gold mining was prominent on the station during the 19th century. The first alluviel 'rush' began in the 1850s, while the more concerted effort to extract gold from Cape Terawhiti followed in the 1880s. The latter of which failed to provide an economic return. Problems arose when miners encountered the fragmented geological landforms that make up much of the Wellington region.

Coastal sediment transport takes place in near-shore environments due to the motions of waves and currents. At the mouths of rivers, coastal sediment and fluvial sediment transport processes mesh to create river deltas. Coastal sediment transport results in the formation of characteristic coastal landforms such as beaches, barrier islands, and capes. A glacier joining the Gorner Glacier, Zermatt, Switzerland.

The glacial till is generally decalcified to 3–4 metres; thinner strata may be entirely decalcified. Very common are wind-formed ablation or accumulation landforms, because during the glacial periods, the wind could easily blow sand and silt away due to the lack of a layer of vegetation. The presence of ventifacts, dunes and loess is thus typical of Old Drift areas.

Lincolnville shoreline c. 1880 Approximately 10,000 years ago, a glacier covered the area to a depth of several thousand feet, carving irregular landforms that survive today. The earliest artifact of European origin was fragments of a 1650-1660 clay pipe, probably a trade good with the native population. First settled in 1774, the town was incorporated in 1802 from Canaan and Ducktrap plantations.

Glacio-geological databases compile data on glacially associated sedimentary deposits and erosional activity from former and current ice-sheets, usually from published peer-reviewed sources. Their purposes are generally directed towards two ends: (Mode 1) compiling information about glacial landforms, which often inform about former ice-flow directions; and (Mode 2) compiling information which dates the absence or presence of ice. These databases are used for a variety of purposes: (i) as bibliographic tools for researchers; (ii) as the quantitative basis of mapping of landforms or dates of ice presence/absence; and (iii) as quantitative databases which are used to constrain physically based mathematical models of ice-sheets. Antarctic Ice Sheet: The AGGDB is a Mode 2 glacio-geological database for the Antarctic ice- sheet using information from around 150 published sources, covering glacial activity mainly from the past 30,000 years.

Ultimately, the variety of volcanic landforms at Pasto Ventura is a consequence of interactions between various factors, such as the speed at which magma rose. Normal faults and strike-slip faults have offset channels, terraces and volcanic cones, but are difficult to recognize. Volcanoes are aligned on older reverse faults. Two thrust faults run in southwest-northeast direction across the area and show evidence of normal displacement.

Eventually this leads to the formation of caves that merge with the remaining central rockmass becoming rauks. The rauks of Gotland formed after the last ice age. It is unclear to which extent different rauks in Gotland started to form from a cliffed coast, a dissected coast or from glacial landforms. Comparison of photographs between 1900 and 1966 has shown some rauks being destroyed between those years.

The island itself is made mostly of granite, like most of the other islands nearby, although there is some sand. Two other islands, Gull Rock and Round Rock, are relatively close to Tuxis, as is Madison Reef to the south, and several unnamed rocks and islets. These landforms are sometimes associated with the Thimble Islands. The name Tuxis comes from the Native words Tuxisshoag and Tuckshishoag.

Lichen studies were conducted on the island in the 1990s to prepare a list of lichens with their habitat, composition and distribution pattern. These studies were considered important for characterizing the eating habits of caribou and air quality. The vegetation of the islands has been classified as wet, moist and alpine tundra, based on landforms and drainage patterns. The plant communities were attributed to five categories.

The resistance of the Montserrat conglomerate to erosion compared to the rest of the fill of the Ebro Basin explains its current mountainous nature. The dominant clast lithology in the conglomerate is limestone and the sequence is cemented by calcite. The presence of so much carbonate in the rock has led to the formation of typical karst landforms, such as cave systems and karst towers.

This meaning is less common in the United States, where topographic maps with elevation contours have made "topography" synonymous with relief. Topography in a narrow sense involves the recording of relief or terrain, the three-dimensional quality of the surface, and the identification of specific landforms. This is also known as geomorphometry. In modern usage, this involves generation of elevation data in digital form (DEM).

The north shore of the Harbour was more lightly populated by settlers than the Sydney side. It was unsuitable for grazing, and the rocky terrain around Middle Harbour probably was deemed difficult to build on. The Griffins' plans included retaining natural landforms and Australian bush plants, and planting additional native flora. Roofs were to be low, and views of the harbour maximised from all areas.

The caprock can consist of either sedimentary rocks such as sandstone and limestone; dissected lava flows; or a deeply eroded duricrust. Unlike plateau, whose usage does not imply horizontal layers of bedrock, e.g. Tibetan Plateau, the term mesa applies exclusively to the landforms built of flat-lying strata. Instead, flat-topped plateaus are specifically known as tablelands.Duszyński, F., Migoń, P. and Strzelecki, M.C., 2019.

Ice melt and rainfall carried large quantities of clay, sand, and gravel from the ice mass. Clays could be moved long distances by moving water, while sand and gravel could not. Thus, sand and gravel landforms developed along the sides and front of the ice sheet; elongated accumulations of this material are known as kames. Mounds along the frontal edge of the ice are called moraines.

Over nearly 2500 years the cycle was repeated many times. Most of the displaced soil created new landforms, but some was carried far out into the Pacific Ocean. In Oregon's Willamette Valley, as far south as Eugene, the cataclysmic flood waters deposited fertile soil and icebergs left numerous boulders from as far away as Montana and Canada. At present day Portland, the water measured deep.

Land-based evidence works acceptably well back as far as MIS 6, but it has been difficult to coordinate stages using just land-based evidence before that. Hence, the "names" system is incomplete and the land-based identifications of ice ages previous to that are somewhat conjectural. Nonetheless, land based data is essentially useful in discussing landforms, and correlating the known marine isotopic stage with them.

The adjacency of water gives a number of distinctive characteristics to littoral regions. The erosive power of water results in particular types of landforms, such as sand dunes, and estuaries. The natural movement of the littoral along the coast is called the littoral drift. Biologically, the ready availability of water enables a greater variety of plant and animal life, and particularly the formation of extensive wetlands.

In the Solinger Platt dialect the word siepenaat means "completely wet through". In East Westphalian Ravensberger Land and in Lipperland such landforms are known as Sieks. But after land amelioration for agriculture, they usually have a trough-shape today. It is possible that there is an etymological relationship between the Middle Low German term for a similar fluvial landform, sike , and the word Siepen.

Tectonic landforms are natural geomorphic landscape features that were formed by tectonic activity. Traditionally, it was believed that many geomorphic landscape features (e.g. valleys, glacial forms, volcanic landscapes, etc.) were formed solely via external, non-tectonic processes, such as water, wind, and ice erosion. However, it is now believed that in almost all cases, geomorphic features were formed by a combination of external and internal mechanisms.

The present landscape of Ireland had more or less formed. Before the Quaternary glaciations affected Ireland the landscape had a thick weathered regolith on the uplands and karst in the lowlands. Pre-Quaternary relief was more dramatic than today's smoothed landforms. Since about 1.7 million years ago, the Earth has been subjected to a cycle of warm and cold stages and these have, inevitably, affected Ireland.

Odziozo, also called Oodzee-hozo, is a giant in Algonquin (specifically Abenaki) legend. His name means "He who Created Himself," or "Transformer." He is attributed with the creation of Lake Champlain, Tuxis Island and Pond, Rock Dunder, and Samson Rock, among other landforms, including mountains and rivers. The legend states that he grew his arms and head from his body, but his legs grew slowly.

Topography is the study of terrain, although the word is often used as a synonym for relief itself. When relief is described underwater, the term bathymetry is used. In cartography, many different techniques are used to describe relief, including contour lines and TIN (Triangulated irregular network). Elementary landforms (segments, facets, relief units) are the smallest homogeneous divisions of the land surface, at the given scale/resolution.

The Coast Mountains are also part of the American Cordilleraa Spanish term for an extensive chain of mountain rangesthat consists of an almost continuous sequence of mountain ranges that form the western backbone of North America, Central America, South America and Antarctica. The Coast Mountains are approximately long and average in width. The range's southern and southeastern boundaries are surrounded by the Fraser River and the Interior Plateau while its far northwestern edge is delimited by the Kelsall and Tatshenshini Rivers at the north end of the Alaska Panhandle, beyond which are the Saint Elias Mountains, and by Champagne Pass in the Yukon Territory.S. Holland, Landforms of British Columbia, Province of British Columbia, 1976, pp 41 map from Bulletin 48: Landforms of British Columbia Covered in dense temperate rainforest on its western exposures, the range rises to heavily glaciated peaks, including the largest temperate-latitude ice fields in the world.

The Rio San Jose, the major tributary to the Rio Puerco, drains much of the Acoma-Zuni Section. The eastern edge of the Acoma-Zuni Section is where the less-deformed rocks of the Colorado Plateau are truncated by the Neogene Rio Grande Rift, from the northern La Jencia Basin, Ladron Mountains, Mesa Lucero, and Rio Puerco fault zone to the southeastern edge of the Sierra Nacimiento. Much of the remainder of the section is late Neogene volcanic landforms—volcanoes (cinder cones and composite cones), lava flows, necks, and dikes, interspersed with erosional and aggradational landforms and bedrock structures typical of the Colorado Plateau. Rocks in the area range in age from Late Triassic to Holocene, including the Triassic Chinle and Wingate Sandstone formations; the Jurassic Entrada Sandstone, Summerville and Zuni Sandstone formations; the Cretaceous Dakota Sandstone; Tertiary gravels and basalts, and Quaternary landslide, eolian, alluvial, and spring deposits.

Many landforms and features remain the same as they were when the gold rushes ceased and are all evocative of the frenzied activity and excitement of the rush period. Remnants of the gardens, orchards, and street plantings have survived and matured to picturesquely complement the remaining structures of the village. This combination of picket fences, ruins, surviving buildings etc., has been of continuing inspiration to many noted Australian artists.

Carl Linnaeus was the first scientist to describe rauks when he visited Gotland in 1741. He called them stenjättar (stone giants) while also noting the ruiniform shape of same rauks. In Sarek National Park rauks originate as aeolian landforms, thus contrary to other rauks, they are shaped more by wind than by water. These rauks are made of sandstone that belong to the Sierggavággenappe () of the Scandinavian Caledonides.

Picture of the Wave Rock, a landmark flared slope in Western Australia. A flared slope is a landform consisting in a rock-wall with a smooth transition into a concavity at the foot zone. Flared slopes form due to weathering being more effective at the regolith or soil-covered base of rock walls. These landforms are common in granitic rocks but occur in other rock types as well, such as ignimbrite.

A glacier ( or ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its ablation over many years, often centuries. Glaciers slowly deform and flow under stresses induced by their weight, creating crevasses, seracs, and other distinguishing features. They also abrade rock and debris from their substrate to create landforms such as cirques and moraines.

The emergence of needle ice has been recognized as a geomorphic agent of soil disturbance, causing a number of small-scale landforms. Needle ice phenomena play a particularly significant role in patterned ground in periglacial environments. The growth of needle ice lifts a detached, frozen soil crust riding on top of the layer of ice. When the crust and the ice melt, the soil surface settles back irregularly.

In general, there are uplifted Tertiary sediments on the east and Quaternary sediments on the western side of the fault. The fault appears to be a northern continuation of the Remolino-El Charco Fault. The fault controls drainage of the Guapi River, locally offsets Quaternary deposits, and forms folded paleosoils, elongated basins and ridges and has strong general linear features. Along the coast, it forms typical fault-controlled linear landforms.

One of those was described in Scientific American on August 25, 1894 as "a remarkable mirage seen by the citizens of Buffalo, New York". Such looming—sometimes with apparent magnification of opposite shores—have been reported over the Great Lakes. Canadian shorelines have been observed from Rochester, New York, across Lake Ontario, and from Cleveland across Lake Erie. The landforms over distant, normally beyond the horizon, were sometimes perceived as away.

Tombolo near Karystos, Euboea, Greece Tombolo contrasted with other coastal landforms. A tombolo is a sandy isthmus. A tombolo, from the Italian tombolo, meaning 'pillow' or 'cushion', and sometimes translated as ayre, is a deposition landform in which an island is attached to the mainland by a narrow piece of land such as a spit or bar. Once attached, the island is then known as a tied island.

The beach sediments that are moving by lateral transport on the lee side of the island will accumulate there, conforming to the shape of the wave pattern. In other words, the waves sweep sediment together from both sides. Eventually, when enough sediment has built up, the beach shoreline, known as a spit, will connect with an island and form a tombolo.Easterbrook, Don T. Surface Processes and Landforms, Second Edition.

Seif and barchan dunes in the Hellespontus region on the surface of Mars. Dunes are mobile landforms created by the transport of large volumes of sand by wind. Rivers and streams are not only conduits of water, but also of sediment. The water, as it flows over the channel bed, is able to mobilize sediment and transport it downstream, either as bed load, suspended load or dissolved load.

Nearly all of Minnesota's glacial landforms derive from the last of them, the Wisconsin glaciation. One feature of this time in the park are the rock ridges near the campground, scoured smooth by the glacier and known as roches moutonnées. Another is the Thomson Moraine, a ridge along the northwest boundary. This terminal moraine comprises rock and debris dropped at the farthest reach of the Laurentide Ice Sheet's Superior Lobe.
|
|
When the Laurentide ice sheet progressed through the process of deglaciation, it created many new landforms and had various effects of the land. First and foremost, as huge glaciers melt, there is a consequently large volume of meltwater. The volumes of meltwater created many features, including proglacial freshwater lakes, which can be sizable. Not only was there meltwater that formed lakes, there were also storms that blew over the inland freshwater.

Talus at the bottom of Mount Yamnuska, Alberta, Canada. Scree is a collection of broken rock fragments at the base of crags, mountain cliffs, volcanoes or valley shoulders that has accumulated through periodic rockfall from adjacent cliff faces. Landforms associated with these materials are often called talus deposits. Talus deposits typically have a concave upwards form, while the maximum inclination corresponds to the angle of repose of the mean debris size.

Sand blowing off a crest in the Kelso Dunes of the Mojave Desert, California. Aeolian landforms are formed when wind moves sediment (see aeolian processes). Sediment particles move when they are lifted by upwards Bernoulli forces that exceed their downwards weight. Depending on the balance of these forces, particles may either creep (roll) across the surface; saltate (hop) from point to point; or be suspended entirely in the air.

The Rhine Falls seen from the Rhine The Rhine Falls were formed in the last ice age, approximately 14,000 to 17,000 years ago, by erosion-resistant rocks narrowing the riverbed. The first glacial advances created today's landforms approximately 500,000 years ago. Up to the end of the Wolstonian Stage approximately 132,000 years ago, the Rhine flowed westwards from Schaffhausen past Klettgau. This earlier riverbed later filled up with gravel.

Coastal and oceanic landforms. Integrated coastal zone management minimizes the negative human impacts on coasts, enhances coastal defense, mitigates the risk associated with the sea level rise and other natural hazards. The beach erosion is a type of bioerosion which alters the coastal geography through beach morphodynamics. There are numerous incidences of modern recession of beaches, mainly due to the longshore drift and coastal development hazards related to human activities.

A moraine would be an easily identified DDA as would an esker. Although scree (talus) is generally easily identified and mapped, these deposits may be modified by ice, avalanches or downlope movement to create essentially new landforms. Many small slope failures and landslides can give the appearance of moraines or protalus ramparts on slopes. After mapping as a DDA, further investigation might draw light on the origin of the feature.

During and following uplift, mountains are subjected to the agents of erosion (water, wind, ice, and gravity) which gradually wear the uplifted area down. Erosion causes the surface of mountains to be younger than the rocks that form the mountains themselves. Glacial processes produce characteristic landforms, such as pyramidal peaks, knife-edge arêtes, and bowl-shaped cirques that can contain lakes.

Dorset has a varied landscape featuring broad elevated chalk downs, steep limestone ridges and low-lying clay valleys. Over half the county is designated as an Area of Outstanding Natural Beauty. Three-quarters of its coastline is part of the Jurassic Coast Natural World Heritage Site due to its geological and palaeontologic significance. It features notable landforms such as Lulworth Cove, the Isle of Portland, Chesil Beach and Durdle Door.

The present-day precipitation has been estimated to be , with other estimates assuming less than . Periglacial landforms indicate that in the past the area was wetter, possibly thanks to the Little Ice Age. There is however no evidence for Pleistocene glaciation including no cirques, which may be due to the volcano's young age. Socompa features autotrophic communities associated with fumaroles and thermal anomalies at high altitude, between of elevation.

Surfaces like this of Saturn's moon Titan (taken by Huygens probe) bear superficial similarities to the floodplains of Earth Another criterion often cited is that an Earth analog must be terrestrial, that is, it should possess a similar surface geology—a planetary surface composed of similar surface materials. The closest known examples are Mars and Titan and while there are similarities in their types of landforms and surface compositions, there are also significant differences such as the temperature and quantities of ice. Many of Earth's surface materials and landforms are formed as a result of interaction with water (such as clay and sedimentary rocks) or as a byproduct of life (such as limestone or coal), interaction with the atmosphere, volcanically or artificially. A true Earth analog therefore might need to have formed through similar processes, having possessed an atmosphere, volcanic interactions with the surface, past or present liquid water and life forms.

Ptolemy's latitudes, longitudes and landforms are often distorted, due to the lack of scientific geography of the times, but his names are not necessarily so. One corrective theory turns the Dauciones into the Danes (Dankiones—Daneiones). This transformation replaces the u with an n and then alters that to make it look Danish. After all, Halland just south of the Goths remained Danish through the Middle Ages until Sweden managed to assimilate it.

These lakes are often surrounded by drumlins, along with other evidence of the glacier such as moraines, eskers and erosional features such as striations and chatter marks. These lakes are clearly visible in aerial photos of landforms in regions that were glaciated during the last ice age. The coastlines near these areas are typically very irregular, reflecting the same geological process. By contrast, other areas have fewer lakes that often appear attached to rivers.

Salinity has varied with location, depth and time. The main factors are the advance or recession of the Scandinavian glacier and the isostatic sinking of the landforms due to the weight of ice or isostatic rebound (springing back) when relieved of it. The glacier provides a massive flow of fresh water. Salt water enters from the North Sea through straits when the sea level is high enough to allow reverse flow over the sill.

In some cases the exposed secondary landforms can be correlated with known seismic events such as the 1855 Wairarapa earthquake on the Wairarapa Fault near Wellington, New Zealand which produced a uplift.Crozier, MJ; Preston NJ (2010): 'Wellington's Tectonic Landscape: Astride a Plate Boundary' in Migoń, P. (ed) Geomorphological Landscapes of the World. Springer, New York, pp. 341–348 This figure can be estimated from the vertical offset between raised shorelines in the area.

In hydrological and fluvial landforms, the thalweg is a line drawn to join the lowest points along the entire length of a stream bed or valley in its downward slope, defining its deepest channel. The thalweg thus marks the natural direction (the profile) of a watercourse. The term is also sometimes used to refer to a subterranean stream that percolates under the surface and in the same general direction as the surface stream.

The Hurricane Fault, and the Hurricane Cliffs strike into southwest Utah as part of the west, and southwest perimeter of the Colorado Plateau. The Hurricane Cliffs are made of Kaibab Limestone, an erosion resistant, cliff-forming rock unit. The Uinkaret volcanic field is a resultant of the two-fault system, at the intersection region. Two example landforms, Vulcan's Throne, and Lava Falls both occur west of Toroweap Point, North Rim Grand Canyon, along the faults.

Lake Estancia is a former lake in the Estancia Valley, central New Mexico. Water levels reached , and during its various stages, leaving various coastal landforms in the valley. Cutthroat trout lived in the lake when it existed, presumably having reached it during a possible past overflowing stage. The lake was mostly fed by water coming from the Manzano Mountains in the form of creek and groundwater and fluctuated between freshwater stages and saltier stages.

Drumlins and drumlin clusters are glacial landforms composed primarily of glacial till. They form near the margin of glacial systems, and within zones of fast flow deep within ice sheets, and are commonly found with other major glacially-formed features (including tunnel valleys, eskers, scours, and exposed bedrock erosion). Drumlins are often in drumlin fields of similarly shaped, sized and oriented hills. Many Pleistocene drumlin fields are observed to occur in a fan-like distribution.

Subsidence resulted in burial by sandstones and limestone (the light-colored rocks) during the early Paleozoic. :3. Uplift during the Pennsylvanian Ouachita Orogeny brought these rocks to the surface as mountains. :4. Weathering and erosion during the Permian Period flattened the mountains and produced a mantle of conglomerates. The mountains themselves are Permian landforms covered and preserved by river- borne sediments in the Permian and partially excavated only in recent geological times.

In geography azonal is an adjective that refers to processes or things that are not restricted to any climate zone. It can be used to describe soils, landforms, geomorphic processes or vegetation. In some climatic environments azonal geomorphologic processes may take distinct characteristics. For example, river activity is common across the globe, but in periglacial environments it causes spring floods from snowmelt, freezing and break-up cycles, and sometimes fluvio-thermal erosion.

In an ecoregion system advanced by the World Wildlife Fund, British Columbia's ecosystems are divided on five different levels, each classifying the area on a progressively more detailed basis. At the top level, ecodomains delineate areas of broad climatic uniformity across the world. The ecodomains are then divided into ecodivisions which delineate areas of broad climatic and physiographic uniformity. Next, the ecodivisions are divided into ecoprovinces which consider climate, oceanography, relief and regional landforms.

During the age of New Imperialism in the late 19th century European explorers and scientists traveled across the globe bringing descriptions of landscapes and landforms. As geographical knowledge increased over time these observations were systematized in a search for regional patterns. Climate emerged thus as prime factor for explaining landform distribution at a grand scale. The rise of climatic geomorphology was foreshadowed by the work of Wladimir Köppen, Vasily Dokuchaev and Andreas Schimper.

In 1995, the painted turtle was named as Michigan's state reptile. Reptile habitats in Michigan are generally split into four regions: the northern and southern Lower Peninsula and the eastern and western Upper Peninsula, with differentiations based on climate, soils, underlying bedrock and glacially-derived landforms. Region one, the southern Lower Peninsula, is generally characterized by a warmer, less variable climate. Loam and clay soils dominate the region, with a lesser amount of sand.

Headward erosion creates three major kinds of drainage patterns: dendritic patterns, trellis patterns, and rectangular and angular patterns. Dendritic patterns form in homogenous landforms where the underlying bedrock has no structural control over where the water flows. They have a very characteristic pattern of branching at acute angles with no common or similarly repeating pattern. Trellis patterns form in where the underlying bedrock where there is repeating weaker and stronger types of rock.

However, their distinctive chemical characteristics and apparent large age differences compared to other volcanics in the Atlin area could also indicate that these columnar-jointed basalt lava flows are not part of the Northern Cordilleran Volcanic Province assemblage. In northern Yukon, similar aged volcanics can be found, including million year old volcanics at Forty Mile and million year old volcanics at Sixty Mile. However, the type of volcanic landforms these volcanics represent are unknown.

Migration theories take into account the terrain monarchs encounter during their migration. Mountains, rivers, lakes and oceans are credited with influencing the migration. Large roosts of migrating monarchs are often formed at a locations that act as obstacles impeding their movement S/SW. Roosting butterflies are thought to form these roosts to wait for ideal weather conditions that will aid them in crossing these landforms, such as lack of rain, temperature, tailwinds, and sunlight.

Average windspeeds are unknown and there are contrasting reports on wind speed extremes but gusts of have been recorded in July and wind speeds in early December 2010 regularly exceeded . Winds blow mainly from the northwest, and have been stable in that orientation for the past 2 million years. This favoured the development of extensive aeolian landforms. Winds kick up pyroclastic material, generating dust storms which remove dust and sand from the area.

The Region holds many of the large predominate landforms in Queensland, the most recognisable is the Glass House Mountains. The Glass House Mountains were formed thousands of years ago when the outer layer of soil and rock eroded from the extinct volcanic summit. The dirt and soil located in the region is very rich and healthy, due to the high quantity of volcanic rock decomposed in the soil. Volcanic rock contains high amounts of nutrients.

The Sugarloaf Mountain of Rio de Janeiro is a typical example of this landform and is the origin of the common bornhardt nickname "sugar loaf". Bornhardts are seen at their best in arid and semi-arid regions, but occur over a wide range of climates. Found in diverse topographic settings they mainly occur in multicyclic landscapes. Over geological time bornhardts may degrade to form other landforms such as nubbins (or knolls) and castle koppies.

Arroyos can be natural fluvial landforms or constructed flood control channels. The term usually applies to a sloped or mountainous terrain in xeric and desert climates. In addition: in many rural communities arroyos are also the principal transportation routes; and in many urban communities arroyos are also parks and recreational locations, often with linear multi-use bicycle, pedestrian, and equestrian trails. Flash flooding can cause the deep arroyos or deposition of sediment on flooded lands.

Connell and Slatyer chose to focus on autogenic succession, which occurs on newly exposed landforms and is initiated by changes from within the community rather than a geophysical transformation.Connell & Slatyer They targeted plant and immobile aquatic organisms that demanded the greatest surface area within an environment and could modify the physical landscape. They defined community as "the set of organisms that occur together and that significantly affect each other's distribution and abundance".

Many hypotheses explain the purpose of petroglyphs, depending on their location, age, and subject matter. Some may be astronomical markers, maps, and other forms of symbolic communication, including a form of proto-writing. Petroglyph maps may show trails, symbols communicating time and distances traveled, as well as the local terrain in the form of rivers, landforms, and other geographic features. A petroglyph that represents a landform or the surrounding terrain is known as a geocontourglyph.

Landscape in the south of New Caledonia New Caledonia has many unique taxa, especially birds and plants. It has the richest diversity in the world per square kilometre. In its botany not only species but entire genera, families, and even orders are unique to the island, and survive nowhere else. The biodiversity is caused by Grande Terre's central mountain range, which has created a variety of niches, landforms and micro-climates where endemic species thrive.

Geographically isolated wetlands encompass saturated depressions that are the result of fluvial, aeolian, glacial and/or coastal geomorphological processes. They may be natural landforms or the result of human interventions. Vulnerable waters represent the major proportion of river networks. These water bodies show vulnerability to natural and human disturbances because they are poorly hydrologically connected, and they are often located in the gray zone of countries and states' protected water regulatory frameworks.

Montes Carpatus has no shortage of volcanic landforms: lava flows, pyroclatic deposits, rilles, and more! Lavas are formed as the mantle begins to melt, so by sampling volcanic rocks of various ages from regions across the Moon scientists can reconstruct the range of compositions and processes over time. The Montes Carpatus formed as a result of the giant impact that formed the mighty Imbrium basin, the mountains are actually the raised rim of the basin.

The sheet erosion caused by a single rainstorm may account for the loss of up to hundred tons of small particles in an acre. It has been argued that in the late Neoproterozoic Era, sheet erosion was a dominant erosion process due to the lack of plants on land. As such, sheet erosion may have contributed to shape important landforms like the Sub- Cambrian peneplain that covers much of the Baltic Shield.

Impact craters and basins, their numerous secondary craters, and heavily to lightly cratered plains are the characteristic landforms of the region. At least six multiringed basins ranging from 150 km to 440 km in diameter are present. Inasmuch as multiringed basins occur widely on that part of Mercury photographed by Mariner 10, as well as on the Moon and Mars, they offer a potentially valuable basis for comparison between these planetary bodies.

412-422 (June 2000) In some glaciers, surges can occur in fairly regular cycles, with 15 to 100 or more surge events per year. In other glaciers, surging remains unpredictable.Summerfield, Michael A., 1991, Global Geomorphology, an introduction to the study of landforms, Pearson, Prentice Hall. Harlow, England In some glaciers, however, the period of stagnation and build-up between two surges typically lasts 10 to 200 years and is called the quiescent phase.

Starting with a topographic map, one can cut out successive layers from some sheet material, with edges following the contour lines on the map. These may be assembled in a stack to obtain a rough approximation of the terrain. This method is commonly used as the base for architectural models, and is usually done without vertical exaggeration. For models of landforms, the stack can then be smoothed by filling with some material.

This dissection has resulted in a variety of landforms, such as valleys, crags and domes. Small graveled creeks flow from alpine mountains out onto the regional prairies where there are pale blue rock-bottomed lakes, including the so-named Itcha Lake. Three streams drain the Itcha Range, namely Corkscrew Creek, Downton Creek and Shag Creek. Although the Itcha Range has been dissected by stream erosion and subsequently glaciated, its original shape has been largely preserved.

Aeolian lakes are lakes produced by wind action. They are found mainly in arid environments although some aeolian lakes are relict landforms indicative of arid paleoclimates. Aeolian lakes consist of lake basins dammed by wind-blown sand; interdunal lakes that lies between well-oriented sand dunes; and deflation basins formed by wind action under previously arid paleoenvironments. Moses Lake, Washington, is an example of a lake basins dammed by wind-blown sand.

He soon became a serious painter, working alongside Andrew Dasburg. He learned the landforms by walking and studying the mountains, mesas, and driftwood, and collecting river rocks. Wells was deeply influenced by Japanese and Chinese philosophies and aesthetics while he was in Japan (1935). His exhibitions were sometimes alongside the work of better known artists such as Mark Tobey, Morris Graves, Adolph Gottlieb, and Jackson Pollack. In addition to Dasburg, he was influenced by Raymond Jonson, and Georgia O’Keeffe.

The effects of the last (Devensian) ice age are the most readily understood. An icesheet which at its maximum extent covered virtually all of Wales and reached as far south as Cardiff, Bridgend and Gower left in its wake suites of both erosional and depositional landforms. The glacial cirques of Snowdonia and to a lesser extent of the Cambrian Mountains and the Brecon Beacons are well known. Many pre-existing valleys were further deepened by glacial ice.

Iowa can be divided into eight landforms based on glaciation, soils, topography, and river drainage. Loess hills lie along the western border of the state, some of which are several hundred feet thick. Northeast Iowa along the Upper Mississippi River is part of the Driftless Area, consisting of steep hills and valleys which appear almost mountainous. Several natural lakes exist, most notably Spirit Lake, West Okoboji Lake, and East Okoboji Lake in northwest Iowa (see Iowa Great Lakes).

Leader of the 1901-1903 Antarctic expedition Nordenskjöld found the Antarctic climate to be glacial, compared to continental or maritime. The expedition found new information about the geological makeup of the Antarctic Peninsula, explaining how the landforms were created. The expedition led to the discovery of fossiliferous rocks deposited during the Cretaceous and Tertiary age. It found that the area was a cordilleran belt of folded strata, overlain by sedimentary rocks and volcanic beds from the Mesozoic time.

The morphostratigraphic approach focuses especially in regions of marine regression on the altitude as the most important criterion to distinguish coast lines of different ages. Moreover, individual marine terraces can be correlated based on their size and continuity. Also paleo-soils as well as glacial, fluvial, eolian and periglacial landforms and sediments may be used to find correlations between terraces. On New Zealand's North Island, for instance, tephra and loess were used to date and correlate marine terraces.

Desert area is shaped by eolian processes and its landforms by erosion and deposition. The stereopairs of aerial photos provide three-dimensional visualization for the land feature while hyperspectral image provide grain scale information for grain size, sand composition etc. The images are often of high phototones in short wavelengths in VNIR corresponding to the scanty vegetation and little moisture. Another tool is radar, which has the capability to penetrate surficial sand, a material of low dielectric constant.

The topography is of limestone that has been worn away through erosion, which later formed ridges, towers, fissures, sinkholes and other types of landforms. The Cat Ba Langur are diurnal animals, adapted to living in limestone habitat.The sleeping caves, ledges, and overhangs used by the langurs are thought to be used as protection from predators and extreme weather. Accessible caves were used as a hunting ground for humans to capture or kill langurs as they slept.

Present-day periglacial conditions in Lapland are reflected in the existence of numerous palsas, permafrost landforms developed on peat. The bedrock of Lapland belongs to the Karelian Domain occupying the bulk of the region, the Kola Domain in the northeast around Lake Inari and the Scandinavian Caledonides in the tip of Lapland's northwestern arm. With few exceptions rocks are of Archean and Proterozoic age. Granites, gneiss, metasediments and metavolcanics are common rocks while greenstone belts are recurring features.

The Cudgel of Hercules, a tall limestone rock in Poland (Pieskowa Skała Castle in the background) The Samulá cenote in Valladolid, Yucatán, Mexico Reflecting lake in the Luray Caverns of the northern Shenandoah Valley The White Cliffs of Dover About 10% of all sedimentary rocks are limestones. Limestone is partially soluble, especially in acid, and therefore forms many erosional landforms. These include limestone pavements, pot holes, cenotes, caves and gorges. Such erosion landscapes are known as karsts.

The study of Geo-ontology has also been of interest to researchers in this field. Geo-ontology involves the study of the variations among different cultures in how they view and sense landforms, how to communicate spatial knowledge with other cultures while overcoming such barriers, an understanding of the cognitive aspects of spatial relations, and how to represent them in computational models.Mark, David M. "Spatial representation: a cognitive view." Geographical information systems: Principles and applications 1 (1999): 81–89.

There are at least 22 cones, and all volcanic landforms older than 12,000 years have been glaciated, the oldest the Soda Peaks basalt lava flows, dated to 0.36 million years old. Trout Creek is a shield volcano. Small in size, it is topped by two nearby cinder cones that produced dark gray olivine basalt lava flows with glomeroporphyritic olivine inclusions. Hornblende andesite can also be found northwest of the Trout Creek Hill volcano, near West Crater.

Likewise, steep slopes are dissected closely with each other particularly those with greater than 18o inclinations. Meanwhile, V-shaped valleys are noted to have been composed and dominated by sandstone. Likewise, landforms in barangays Dolo, Sabang, part of Minoro, Manzana and Tagas are noted to be flat with very poorly drained terrains and oftentimes affected by floods caused by high tides. The coastal plains are most commonly swarmed with mangroves, nipa plants, break rides, swales and tidal flats.

Terrain measurement techniques are vital to quantitatively describe the form of the Earth's surface, and include differential GPS, remotely sensed digital terrain models and laser scanning, to quantify, study, and to generate illustrations and maps.e.g., DTM intro page, Hunter College Department of Geography, New York. Practical applications of geomorphology include hazard assessment (such as landslide prediction and mitigation), river control and stream restoration, and coastal protection. Planetary geomorphology studies landforms on other terrestrial planets such as Mars.

As a result of erosion and transportation of unconsolidated material, landforms such as beaches and marshes are being formed. These deposits are also being eroded and/or flooded by the rising sea level. Glaciation during the Quaternary Period had an overwhelming effect upon the landscape. Glaciers abraded and plucked at the bedrock during their advances across the country, creating various deposits that vary in thickness and form; in some places, they are up to 300 meters thick.

The topography of the Yellow Bluffs location is attributed to Pleistocene glaciations which created the surrounding landforms and drainage systems. Today, Logan county is found on a rolling glacial till plain situated between two pronounced glacial moraine ridge systems. The prehistoric environmental conditions of the Yellow Bluffs site differed from the typical central Illinois landscape in two ways. The site remarkably had a large lake feature along with the presence of an area with dense woodland vegetation.

Arrow Canyon Wilderness is made up of three distinct landforms: the craggy Arrow Canyon Range; wide valleys; and deep canyons. The Arrow Range lies along the west edge of the wilderness. This craggy block of tilted sedimentary carbonate rock exposes the underlying strata along the west side of the ridge. This fault scarp is several thousand feet high and is marked by black and white bands of carbonate rock and quartzite that run the length of the entire range.

The island is part of the Great Lakes–St. Lawrence lowlands physiological region, a fertile plain that is composed primarily of post-glacial landforms. The island was formed by debris and erosion at the end of the last glacial period. As the Laurentide Ice Sheet, a huge glacier extending into the present-northern United States, melted about 11,000 years ago, it carved deep gouges into the earth, scraped off top soil and deposited rock and sand.

The Valbonë Valley National Park in northern Albania. The Environment of Albania is characterised by unique flora and fauna and a variety of landforms contained within a small nation. It also consists of different ecoregions, which represent the natural geographical ecosystem, water systems, weather, renewable resources and influences upon them. Of the factors caused by human intervention that can affect this environment, activities that sustain the economy of Albania such as mining and forestry are notably influential.

Others have proposed that certain landforms were produced by glacial rather than liquid flow. Three sets of enormous cataracts (dry falls) are present in the area between an "island" feature in the southern channel, Lunae Mensae, and the crater Sharonov. These cataracts, evidently carved during megaflooding events, have headwalls up to 400 m high and are considerably larger than the largest terrestrial analog, Dry Falls. They may have migrated over 100 km upstream subsequent to their initial formation.

The Oak Ridges Moraine is an ecologically important geological landform in the Mixedwood Plains of south-central Ontario, Canada. The moraine covers a geographic area of between Caledon and Rice Lake, near Peterborough. One of the most significant landforms in southern Ontario, the moraine gets its name from the rolling hills and river valleys extending from the Niagara Escarpment east to Rice Lake. It was formed 12,000 years ago by advancing and retreating glaciers (see geological origins, below).

The Edaga Arbi Glacials fill the bottom of north-south oriented valleys, that were carved by glaciers, into the Precambrian basement and in Early Palaeozoic sediments. These valleys were often several kilometres wide and tens of meters deep. Indeed, northern Ethiopia was glaciated in the Early Palaeozoic (Late Ordovician; ~445 Ma), and in the Late Palaeozoic (Carboniferous-Permian; ~300 Ma). This has led to the presence of glacial sediments as well as erosional landforms in eastern Tigray.

The neighboring islands and islets have similar landforms. The island is within the jurisdiction of the province of Surigao del Norte and is composed of the municipalities of Burgos, Dapa, Del Carmen, General Luna, San Benito, Pilar, San Isidro, Santa Monica and Socorro. Currently, General Luna is the most popular and well visited municipality by both local and foreign tourists. It is where you will find most of the resorts, restaurants, cafes and other establishments in the island.

Bornhardts were previously thought of as characteristically tropical landforms, but have been shown to be more related to lithology and rock structure than climate. Depending on their shape they are known as sugar loaves, whalebacks, turtlebacks or simply domes. They are locally known as dwalas, half-oranges, matopos, etc. Often, the underlying geological fracture pattern is shown by the surface arrangement of bornhardts, as can be seen in the Kamiesberge of Namaqualand and the Everard Ranges of Central Australia.

Caves are found around the world. The largest form in areas of karst landforms whose rocks erode easily. Preferable conditions for cave formation are adequate precipitation, enough plants and animals to produce ample carbon dioxide, and a landscape of gentle hills which drains slowly. The highest concentrations of long caves in the world are found in the Pennyroyal Plateau of southern Kentucky, United States, in the Black Hills of South Dakota, United States, and in the Yucatán Peninsula, Mexico.

Plateaus can also be formed by the erosional processes of glaciers on mountain ranges, leaving them sitting between the mountain ranges. Water can also erode mountains and other landforms down into plateaus. Dissected plateaus are highly eroded plateaus cut by rivers and broken by deep narrow valleys. Computer modeling studies suggest that high plateaus may also be partially a result from the feedback between tectonic deformation and dry climatic conditions created at the lee side of growing orogens.

The Mingyue Mountain in Beishan Town is the highest peak with an elevation of 659 meters above sea level. The terrain gradually tilts from the north, east and south to the central and western regions, forming an irregular "dustpan" shape. There are seven types of rock layers in metamorphic rocks, glutenite, limestone, red rock, laterite, sand shale and granite. It is divided into five types of landforms: hillocks, plains, mountains, hills and waters, mainly hillocks and plains.

King, Cuchlaine; Landforms and Geomorphology: Concepts and History, Wiley, 1976 It is argued, however, whether these excessively stormy periods are the sole cause of arroyo-cutting as other factors such as long-term climate changes must also be taken into account.Rice, R. J.; Fundamentals of Geomorphology, Longman, 1988 Arroyo cutting which occurred in the 1900s in the southwestern United States caused serious farming issues such as a lowered water table and the destruction of agriculture and grazing lands.

The landforms are the result of the Wisconsin glaciation during the last glacial period, which lasted from about 110,000 to 10,000 years ago. The nine units of the reserve, mostly Wisconsin state parks or other protected areas, are administered by the Wisconsin Department of Natural Resources. Several units are not yet developed for visitation, having only minimal trails and no interpretive installations. Planning was underway for the future development and management of the Cross Plains unit.

The steep profile of the volcanic field and its subglacial landforms support this hypothesis. As a result, volcanic features in the field that interacted with glacial ice lack rocks that display evidence of abundant water during eruption, such as hyaloclastite and pillow lava. Of the entire volcanic field, the southern portion has the most known volcanoes. Here, at least 11 of them are situated on top of a long narrow mountain ridge and in adjacent river valleys.

Glacial landforms, the arête Striding Edge and a cirque filled by Red Tarn The Quaternary saw repeated glaciations of the Lake District area with the development of an ice cap, although the current landscape is the result of the Last glacial period, which occurred over the period 115,000 to 11,700 years ago. As the Lake District was an upland area it was unaffected by the main British-Irish ice sheet, which flowed around the margins of the massif.

An ecoregion may be analyzed on physical, biological, and cultural levels. First, we map the landforms, geology, climate, and hydrology, and how these environmental factors work together to create a common template for life in that particular place. Second, we map the flora and fauna, especially the characteristic vegetative communities, and link them to their habitats. Third, we look at native peoples, western settlement, and current land-use patterns and problems, in interaction with the first two levels.

The land slopes in a series of "terraces" in the west and goes into an incline in the east. A large proportion of the island is circled by coral reefs. The erosion of limestone in the northeast of the island, in the Scotland District, has resulted in the formation of various caves and gullies. On the Atlantic east coast of the island coastal landforms, including stacks, have been created due to the limestone composition of the area.

The town of Molina de Segura is located in Europe, in the east of the Iberian Peninsula, belonging to the kingdom of Spain, and part of the Region of Murcia. The township has an area of 169 km2 with flora and fauna belonging to the very dry Mediterranean climate (340 mm of rainfall per year) to which it belongs. Some landforms in the municipality are Sierra de la Espada (a mountain range) and Rambla del Chorillo.

Large amounts of water ice are believed to be present in the Martian subsurface. The interaction of ice with molten rock can produce distinct landforms. On Earth, when hot volcanic material comes into contact with surface ice, large amounts of liquid water and mud may form that flow catastrophically down slope as massive debris flows (lahars). Some channels in Martian volcanic areas, such as Hrad Vallis near Elysium Mons, may have been similarly carved or modified by lahars.

2 When his financial circumstances later improved, he became a patron and collector. He amassed a considerable collection of works of art, many of which had been commissioned and which were selected for their scientific interest rather than their connoisseur value. He had several works by Nicholas Pocock representing topographical landforms, mostly in Wales, and others by the artist Peter Paillou, probably commissioned, representing different climate types. His portrait by Thomas Gainsborough shows him as a country gentleman.

About 140 million years ago, the sea leaching in the Changsha area ended and it became a land. Due to the influence of crustal movement and geological structure, a long-shaped mountain depression basin, the Chang (Sha) Ping (Jiang) Basin, was formed. Beginning of the new generation, the entire Changping Basin has risen to land. About 3.5 million years ago, the third ice age occurred on the earth, and Liuyang retained the remains of glacier landforms.

Upper Ear Falls was drowned out by the dam, and well known landforms around the lake disappeared under the water level. Ontario Hydro played an instrumental role in the development of Ear Falls. The company realized that many of its generating stations in Northern Ontario were situated in isolated areas. In order to retain operators for these plants, the company recognized that they would need to supply quality housing, schools, recreation halls, stores, hospitals and other buildings.

A turlough, or turlach, is a type of disappearing lake found mostly in limestone areas of Ireland, west of the River Shannon. The name comes from the Irish tur, meaning "dry", with the suffix -lach, meaning "a place" (in an abstract sense). The -lach suffix is often mistakenly spelled and/or thought to refer to the word loch, the Irish, Scottish Gaelic and Scots word for "lake". The landforms are found in Irish karst (exposed limestone) areas.

The changing level of the Caspian Sea has resulted in three distinct zones in the delta. The higher areas of the first zone are known as "Baer's mounds," named after researcher Karl Ernst von Baer who worked in this region. These mounds are linear ridges of clayey sands, ranging from 5 to 22 m in height (averaging about 8 m) and 400 m to 10 km in length.Eric Bird, , 'Encyclopedia of the World's Coastal Landforms, vol.

Rivers draining the eastern part of the state, the Yu River Basin, include the Chamu, Khunou and other short streams. Manipur may be characterised as two distinct physical regions: an outlying area of rugged hills and narrow valleys, and the inner area of flat plain, with all associated landforms. These two areas are distinct in physical features and are conspicuous in flora and fauna. The valley region has hills and mounds rising above the flat surface.

Before the first human settlement of the area, the ice cap on Coropuna was much larger than today, with its surface exceeding and its glaciers descending to much lower elevations. Additionally, glaciers also expanded from the mountains Pumaranra, Pucaylla and Cuncaicha to the east of Coropuna. They covered the Pampa Pucaylla northeast from Coropuna and descended the Jellojello valley and other valleys to the east. Glacial valleys radiate from Coropuna, and glaciofluvial landforms are associated with moraines.

Volcanism in the Eifel began about 600,000 years ago and led to the formation of numerous volcanic landforms. What was probably the last eruption, which led to the formation of the Ulmener Maar, was about 11,000 years ago. Within those timeframes the Boos maars belong to the youngest formations in the Volcanic Eifel. C14 dating of rocks from the maars as well as of organic material have suggested an age of 14,160 years for the eastern maar.

Kimolos, Milos and the smaller islands that surround them belong to the Aegean volcanic arc and consist mainly of acidic volcanic rocks. In some places, the pre-volcanic bedrock can be observed. Large areas of Kimolos are covered by tuffs and the volcanic activity can be obvious from the hot springs, existence of a notable geothermal field, the characteristic landscape and strange landforms. The island is also rich in minerals of the silica group and in significant industrial minerals.

From the south, at the corner of Clarke and Montefiore Streets, the dramatic landforms of the headland and beach dominate rows of small houses stepping down the hill. From the north, along Flowers Drive through Middle Camp, the jetty and headlands are visible. Against this striking backdrop, the character of the streets derives from the low-scale built form and highly consistent pattern of predominantly single storey weatherboard cottages. This reflects the historical association with the coal company.

Weathering rinds have a long history of being used to determine the relative age of either Quaternary sediments or landforms. This is done by comparing the thickness of weathering rinds of gravel composed of similar rock types. Deposits containing gravel with thicker weathering rinds are interpreted to be older than deposits containing rocks with thinner weathering rinds. Sedimentary deposits containing gravel with weathering rinds of the same thickness are interpreted to be approximately contemporaneous in age.

Later, when the glaciers retreated leaving behind their freight of crushed rock and sand, depositional landforms were created, such as moraines, eskers, drumlins, and kames. The stone walls found in New England (northeastern United States) contain many glacial erratics, rocks that were dragged by a glacier many miles from their bedrock origin. At some point, if an Alpine glacier becomes too thin it will stop moving. This will result in the end of any basal erosion.

The explosion craters on the summit are the youngest volcanic landforms on Socompa, there are no dates available for the lava domes and flows within the collapse scar. The youngest eruption was dated to have occurred 5,250 years before present. The absence of moraines on Socompa suggests that volcanic activity occurred during the post-glacial time. The volcano also has a young appearance, similar to historically active Andean volcanoes such as San Pedro, implying recent volcanic activity.

With the notation "changed by His Majesty's command" included, John Ross made changes to the chart: he added six islands and three capes, all with royal Clarence and Fitz-Clarence family names (including Munster Island, Falkland Island, Erskine Island, Fox Island, Errol Island, Cape Sophia, Cape Sidney, and Cape Mary), and renamed the island group "Clarence Islands". While as leader of the expedition, John Ross had authority to name newly charted landforms as he wished, he did not receive authority to add fictional landforms to navigation chart books. Lady Jane Franklin documented in her diary a meeting she had with Capt. Beaufort regarding the controversial chart book changes: > Captain B. asked me if Sir John's ire had abated against (James) Ross, and > he (Captain B.) seemed much tickled at this subject - he was not one he said > to take away a man's fair character, but there were some things that ought > to be held up to reprobation, and he was now going to tell me a good story.

The preferred habitat of the Adonis blue is calcareous grasslands with hot and dry conditions. This is because the larva feeds on horseshoe vetch (Hippocrepis comosa) which is largely restricted to these habitats. This plant flourishes on sheep-grazed pastures and disappears after a few years when cattle graze. Sometimes human-created landforms provide refuges for the plant and the butterfly; an example of this is on Martin Down in Dorset, where horseshoe vetch only occurs on ancient earthworks with thin calcareous soils.

The ice ages left their mark on the Rockies, forming extensive glacial landforms, such as U-shaped valleys and cirques. Recent glacial episodes included the Bull Lake Glaciation that began about 150,000 years ago and the Pinedale Glaciation that probably remained at full glaciation until 15,000–20,000 years ago. Ninety percent of Yellowstone National Park was covered by ice during the Pinedale Glaciation. The little ice age was a period of glacial advance that lasted a few centuries from about 1550 to 1860.

Using reflection seismology, this documentary demonstrated techniques that what Sarmast interpreted to be artificial walls are natural tectonic landforms. Furthermore, the interpretation of the age and stratigraphy of sediments blanketing the bottom of the Cyprus Basin from sea bottom cores containing Pleistocene and older marine sediments and thousands of kilometers of seismic lines from the Cyprus and adjacent basins clearly demonstrates that the Mediterranean Sea last dried up during the Messinian Salinity Crisis between 5.59 and 5.33 million years ago.Emeis, K.-C.

The landscape of Greenland contains many pingos and other glacial landforms. In western Greenland it is estimated that there are 29 pingos, whilst in eastern Greenland it is estimated there are 71 pingos. The majority of pingos in Greenland are located within Disko Bay and Nuussuaq Peninsula within western Greenland as well as some in eastern Greenland in Mesters Vig. The thickness of the permafrost at Disko Bay is around deep, making it ideal for closed system pingos to develop.

On these landforms, masked boobies select sites of generally flat, bare or exposed open ground that lie above the high-tide level with access to the ocean. During the breeding season, the species remains near the colony. At other times, juveniles and some adults disperse widely, though some remain at the colony year-round. Most (but not all) birds return to breed at the colony of their birth; once they begin breeding at a site, they will return there annually.

During the Permian era, Europe, Africa, Asia, America, and Antarctica were joined in one large supercontinent called Pangea. Scattered fossils of Anomodonts provide evidence for this huge land mass as well as for migration from one end of the land mass to the other. Fluvial sedimentation refers to the sediment carried by streams and rivers that deposit into landforms, thus preserving the fossil skull of Patranomodon. These streams and rivers were most likely formed by ice masses such as glaciers.

Rock Bridge Memorial State Park is a geological preserve and public recreation area encompassing , south of Columbia in Boone County, Missouri. The state park is noted for its excellent examples of karst landforms including the rock bridge, sinkholes, and an underground stream at the cave known as Devil's Icebox. The rock bridge was created by the collapse of a section of a cave which resulted in a small arch of rock being left to form a natural bridge over the creek.

The avenue is located on the former stream bed of a branch of the Mapocho River, which was drying up between 1560 and 1580. Such landforms were known by the Spaniards as Cañadas, and from there the origin of its initial name of Cañada. For many decades it was used as a landfill site, until it was converted into a boulevard by Bernardo O'Higgins during the first years of independence of the country and was named as Alameda de las Delicias.

A map showing the distribution of paha with the major rivers on the boundary of the Iowan Surface. Paha (or greda) are elongated landforms composed either of only loess or till capped by loess. In Iowa, paha are prominent hills that are oriented from northwest to southeast, formed during the period of mass erosion that developed the Iowan surface, and they are considered erosional remnants since they often preserve buried soils. Paha generally rise above the surrounding landscape more than .

Collision of oceanic plates often cause specific landforms like volcanic arc systems, and divergent plates cause trenches and seafloor spreading patterns and both are secondary formations due to the greater tectonics of this area. These structures are seen in the GTJ area, implying that not only divergent boundaries are present but smaller convergent/transform as well. Determining relative ages of the geology in the area is challenging due to consistent volcanic activity along spreading ridges and trenches bordering each plate boundary.

According to British cave scientists, Tiên Sơn cave was created tens of million years ago when a water current holed this limestone mount in Kẻ Bàng. Following a series of landforms and movement of rocks, this mass was levered or lowered, blocking the current and creating what is now Tiên Sơn cave while the underground river redirected its current to Phong Nha cave. Although Phong Nha and Tiên Sơn caves are located next to each other, there are no linking grottos between them.

The larger part of lowland Lancashire i.e. the West Lancashire Coastal Plain, The Fylde and adjoining areas is covered by a thick mantle of glacial till. These deposits are the legacy of the over-riding of the area on several occasions by glacial ice during the past 2 million years. The present distribution of deposits and the landforms to which they give rise are largely the result of the last ice age, the Devensian which peaked around 22-20,000 years ago.

Borders articulate the natural envelope of the place–its centers and bounds–and link this diversity into the larger world. Since ecological systems are open and lack definite boundaries, in complex terrain, watersheds are often used to represent ecosystems on a landscape level. Here, ecoregions are often drawn as a series of contiguous watersheds with similar character and context. However, where other factors predominate–such as landforms, tectonic suites, regional rivers, vegetative breaks, or major cultural boundaries–then watershed lines may be crossed.

During the past 20 years in his research at Boston University, El-Baz has utilized satellite images to better understand the origin and evolution of desert landforms. He is credited with providing evidence that the desert is not man-made, but the result of major climatic variations. His research uncovered numerous sand-buried rivers and streams in the Sahara based on the interpretation of radar images. These former water courses lead into depressions in the terrain, which he theorized must contain groundwater.

The landforms of the Great Lake – St. Lawrence Lowlands, with its rolling hills and slopes, were carved by glacial streams. Two of the most prominent geological features include the Niagara Escarpment and the Frontenac Axis. The Niagara Escarpment bifurcates the region from Niagara Falls to the northern tip of the Bruce Peninsula, then extends to Manitoulin Island. The Frontenac Axis, is an exposure of Canadian shield rocks that extends south to the St. Lawrence River near Kingston, creating the Thousand Islands.

The study of how landforms are created by inner Earth processes was a topic heavily focused on in the mid-20th century, frequently appearing in geomorphology and geology textbooks. However, the term morphotectonics was not coined until 1961 by Edwin Hills, who defined the field as involving "a study of the external form and outlines of major topographic units...as well as their internal structure". After the 1960s, the field became neglected until a resurgence of morphotectonic literature in the 1980s.

Prehistoric rock engravings and paintings occupy a prominent place among Kazakhstan's monuments. Rock engravings, or petroglyphs, embossed in the rock with stone or metal tools, are particularly common, and the geology and landforms of the country's mountain ranges lent themselves to the proliferation of this art form. The absence of anthropogenic impact across most of the country has resulted in preservation of many of these monuments, providing rich material for study. The earliest examples of art in Kazakhstan are Paleolithic.

In limnology (the study of inland waters), a stream bank or river bank is the terrain alongside the bed of a river, creek, or stream. The bank consists of the sides of the channel, between which the flow is confined. Stream banks are of particular interest in fluvial geography, which studies the processes associated with rivers and streams and the deposits and landforms created by them. Bankfull discharge is a discharge great enough to fill the channel and overtop the banks.

The stream or river will continue to deposit material until an equilibrium is reached and it can transport the material rather than deposit it. This equilibrium may last for a very short period, such as, after glaciation, or for a very long time if the conditions do not change. The fill terrace is created when the conditions change again and either a stream or river starts to incise into the material that it deposited in the valley.Easterbrook, Don J., 1999, Surface Processes and Landforms, 2nd Edition.

Environmental impacts such as pollution and vandalism of geothermal landforms has been documented. Safety warning sign El Tatio displays some typical hazards of geothermal areas. Exposure to the hot gases and water can result in burn injuries, and both sudden eruptions of geysers and fountains and fragile ground above vents and above boiling water, concealed beneath thin covers of solid ground, increase the risk to unwary travelers. The site lies at high altitude, frequently leading to altitude sickness, and the cold dry climate creates further danger.

One of the youngest and flattest regions in Iowa, the Des Moines Lobe ecoregion is a distinctive area of Wisconsinan glacial stage landforms currently under extensive agriculture. In general, the land is level to gently rolling with some areas of the moraines having the most relief. The morainal ridges and hummocky knob and kettle topography contrast with the flat plains of ground moraines, former glacial lakes, and outwash deposits. A distinguishing characteristic from other parts of Ecoregion 47 is the lack of loess over the glacial drift.

Siltation In geology, sedimentation is the deposition of particles carried by a fluid flow. For suspended load, this can be expressed mathematically by the Exner equation, and results in the formation of depositional landforms and the rocks that constitute sedimentary record. An undesired increased transport and sedimentation of suspended material is called siltation, and it is a major source of pollution in waterways in some parts of the world. High sedimentation rates can be a result of poor land management and a high frequency of flooding events.

Rock glacier with multiple flow lobes, Chugach Mountains, Alaska. Rock glaciers are distinctive geomorphological landforms, consisting either of angular rock debris frozen in interstitial ice, former "true" glaciers overlain by a layer of talus, or something in-between. Rock glaciers may extend outward and downslope from talus cones, glaciers or terminal moraines of glaciers. There are two types of rock glaciers: periglacial glaciers (or talus-derived glaciers), and glacial rock glaciers, such as the Timpanogos Glacier in Utah, which are often found where glaciers once existed.

Being often concerned about past climates climatic geomorphology considered sometimes to be an aspect of historical geology. Since landscape features in one region might have evolved under climates different from those of the present, studying climatically disparate regions might help understand present-day landscapes. For example, Julius Büdel studied both cold-climate processes in Svalbard and weathering processes in tropical India to understand the origin of the relief of Central Europe, which he argued was a palimpsest of landforms formed at different times and under different climates.

The provincial system was abolished in 1876. Auckland Province was from then used as an administrative district by the Department of Lands and Survey, but the area was later subdivided into the North Auckland, South Auckland, and Gisborne land districts. The 39th latitude was subsequently replaced by boundaries that took landforms into account, and as a consequence, parts of the former Auckland Province are now in the Wellington and Hawke's Bay land districts, and part of the former Wellington Province is in the South Auckland Land District.

A granite outcrop in the Stirling Range National Park Granite outcrops of Western Australia are weathered landforms that occur throughout the state of Western Australia, composed primarily of the rock type granite. All recognised types of this landform can be observed, commonly as bornhardts, but also as inselbergs, castle koppies and Nubbins. Rising abruptly from the surrounding landscape they create a variety of microhabitats for plants, and provide seasonal resources and refuge for a range of animals. These areas thus have rich biodiversity and many endemic species.

The sectors normally contain a number of island-like landforms at the bottom of the screen, which may support various emplacements of the enemy tartillians. Some of these are active, shooting at the player's ship, while others are inactive but can be shot for points. Enemies also appear and approach the ship in order to collide with it. All of the active targets, if any, must be destroyed before the ship will advance to the next sector when it reaches the left side of the screen.

Being relatively stable regions the relief of shields is rather old with elements such as peneplains being shaped in Precambrian times. The oldest peneplain identifiable in a shield is called a "primary peneplain", in the case of the Fennoscandian Shield this is the Sub-Cambrian peneplain. The landforms and shallow deposits of northern shields that have been subject to Quaternary glaciation and periglaciation are distinct from those found in closer to the equator. Shield relief, including peneplains, can be protected from erosion by various means.

Beechmont is positioned on a forested ridge leading from the Lamington Plateau to Tamborine Mountain. Outstanding views in nearly all directions means that on a clear day Cunninghams Gap and other Scenic Rim landforms are visible as well as Flinders Peak, Moogerah Peaks and the D'Aguilar Range to the north west of Brisbane. Lower Beechmont is also on the Beechmont road, but slightly lower down the hill. Roads in the area are narrow and windy, some are prone to rockfalls and some with very steep slopes.

A river terrace is composed of an abandoned surface, or tread, and the incised surface, or riser.Easterbrook, D.J., 1999, Surface Processes and Landforms: New York, New York, Prentice Hall, 546 p. If you can date the age of the terrace tread, one can get an estimate of the age of abandonment of that surface, and the age of incision. A simple calculation of h1/t1 can give the average rate of incision(ri), where hi = height of river terrace from river and ti = age of surface.

Its coastline has a considerable length of . The coast has a particular character because it is rich in varieties of virgin beaches, capes, coves, covered bays, lagoons, small gravel beaches, sea caves and many landforms. Some parts of this seaside are very clean ecologically, which represent in this prospective unexplored areas, which are very rare within the Mediterranean. Other attractions include the mountainous areas such as the Albanian Alps, Ceraunian Mountains and Korab Mountains but also the historical cities of Berat, Durrës, Gjirokastër, Sarandë, Shkodër and Korçë.

Many large valleys formed by the lava erupted from the volcanoes of Mars cut through the dichotomy. The Martian dichotomy boundary includes the regions called Deuteronilus Mensae, Protonilus Mensae, and Nilosyrtis Mensae. All three regions have been studied extensively because they contain landforms believed to have been produced by the movement of ice or paleoshorelines questioned as formed by volcanic erosion. The northern lowlands comprise about one-third of the surface of Mars and are relatively flat, with as many impact craters as the southern hemisphere.

The geological history of the formation may be traced back some 50 million years, when the uplift of the continental margin in the region created modern landforms. The Herbert River, which previously flowed west, began to cut through the terrain en route to its outflow in the Coral Sea. The gorge produced by this erosive action gradually retreated inland along the Herbert River's course at a rate of per hundred years. The river's tributaries were eventually left suspended by this action, forming their own gorges.

347 Wind or rare rainfall shape the desert features: sand dunes, dune fields, sand seas, stone plateaus, gravel plains (reg), dry valleys (wadi), dry lakes (oued), and salt flats (shatt or chott). Unusual landforms include the Richat Structure in Mauritania. Several deeply dissected mountains, many volcanic, rise from the desert, including the Aïr Mountains, Ahaggar Mountains, Saharan Atlas, Tibesti Mountains, Adrar des Iforas, and the Red Sea Hills. The highest peak in the Sahara is Emi Koussi, a shield volcano in the Tibesti range of northern Chad.

Castle Rock, the butte for which the town is named, is just north of the town center. Other prominent landforms visible from Castle Rock include Dawson Butte, Devils Head, Mount Evans, and Pikes Peak. East Plum Creek, a stream within the South Platte River watershed, flows generally north through Castle Rock. Hangman's Gulch, which runs northwest then west around the north side of the town center, drains into East Plum Creek, as do multiple unnamed gulches in the southern and western areas of town.

Some researchers have interpreted these landforms as originating in the erosion of sulfate-bearing layers present within units of Ganges Mensa. Ganges Mensa is in the Coprates quadrangle of Mars, centered near the equator in the western hemisphere at 7.2° S and 48.8° W. The landform was named after a classical albedo feature that was published in a 1930 manuscript called La Planéte Mars authored by the French-Greek astronomer Eugène Michel Antoniadi. The International Astronomical Union officially approved Ganges Mensa's name in 2006.

Kettles are fluvioglacial landforms occurring as the result of blocks of ice calving from the front of a receding glacier and becoming partially to wholly buried by glacial outwash. Glacial outwash is generated when streams of meltwater flow away from the glacier and deposit sediment to form broad outwash plains called sandurs. When the ice blocks melt, kettle holes are left in the sandur. When the development of numerous kettle holes disrupt sandur surfaces, a jumbled array of ridges and mounds form, resembling kame and kettle topography.

Great Hohlohsee On the southern part of the plateau is the Hohlohmiss, a misse with raised bogs and several bog ponds, including the Great and Little Hohlohsee. Like the neighbouring Wildseemoor, these are biogenic and not geomorphological landforms. They have developed since the last ice age about 10,000 years ago due to the high rainfall on the acidic klebsands of the upper conglomerate horizon of Middle Bunter. Due to their outstanding ecological importance, the Hohlohmiss and Wildseemoor have been protected as part of the Kaltenbronn Nature Reserve.

Creation science rejects evolution and the common descent of all living things on Earth. Instead, it asserts that the field of evolutionary biology is itself pseudoscientific or even a religion. Creationists argue instead for a system called baraminology, which considers the living world to be descended from uniquely created kinds or "baramins." Creation science incorporates the concept of catastrophism to reconcile current landforms and fossil distributions with Biblical interpretations, proposing the remains resulted from successive cataclysmic events, such as a worldwide flood and subsequent ice age.

The sink has a long history of human habitation. In addition to Lovelock Cave, an outcrop in the West Humboldt Range in which 2000-year-old duck decoys have been found, there is also evidence of huts constructed in the bed of Lake Humboldt. Evidence from these important archaeological sites suggests that Native Americans hunted and fished in the Humboldt Sink during wetter climatic periods. These landforms are named for the Humboldt River, which is in turn named after German naturalist Alexander von Humboldt.

It consists of mostly monogenetic scoria cones, each of which produced three or four lava flows. There are at least 22 cones, and all volcanic landforms older than 12,000 years have been glaciated, the oldest the Soda Peaks basalt lava flows, dated to 0.36 million years old. The West Crater-Soda Peaks zone covers an area of , to the southeast of Mount St. Helens. A monogenetic volcanic field, it consists of 13 basaltic to andesitic volcanic edifices that vary from 360,000 years old to 2,000 years old.

Its mouth is to the southwest of the Baie des Sept-Îles. During the Holocene the Sainte-Marguerite created a delta of thick paraglacial and post-glacial sediments that completely cover the glacial landforms and glaciomarine deposits near the river mouth. The river mouth today is a haven for small boats during bad weather in the Gulf, because the basin that it forms is protected by the Pointe Sainte-Marguerite. However, the channel of the river through the basin varies from year to year.

The Sichuan Giant Panda Sanctuaries are the most well- known of their kind in the world, with Wolong Nature Reserve, generally considered as the "homeland of pandas". It is a core habitat with unique natural conditions, complicated landforms, and a temperate climate with diverse wildlife. Siguniang Mountain, sometimes called the "Oriental Alpine" is approximately away from Chengdu, and is composed of four adjacent peaks of the Traversal Mountain Range. Among the four peaks, the fourth and highest stands above sea level, and is perpetually covered by snow.

At shallow depths it is common for submarine eruptions to be explosive due to the reaction between volatiles in the magma and water which generates a significant quantity of steam.Head, J.W. and Wilson, L. (2008) Deep submarine pyroclastic eruptions: theory and predicted landforms and deposits, Journal of Volcanology and Geothermal Research, 121: 155-193. These eruptions described as Surtseyan are characterised by large quantities of steam and gas and creating large amounts of pumice., Smithsonian Institution National Museum of Natural History Global Volcanism Program (2013).

While the mountains of the Sierra near the meadows have had some permanent snowfields, in the summer they are mostly free of snow. Although brief, the late spring and summer wildflower bloom in Tuolumne Meadows is host to a wide variety of California wildflowers, including the relatively rare Purple Webber, a type of lupin. Plant species composition changes across the meadows with different landforms, landscape positions, and summer water-table depths. Areas with seasonal flooding and deep-standing water support the inflated sedge and Sierra willow.

Dongao Dongao () is a port located in the east of Siyin, facing Beiao () of Dongyin in distance. Before the jetties were built between Dongyin and Xiyin (Siyin), Dongao was one of the important transportation hubs on Xiyin (Siyin). Lack of vast tidal flats in Dongyin, the pebble beach in Dongao is one of few ports that give easy access to the sea. It’s the best spot to enjoy the sights of coastal landforms, such as sea arches, sea gulfs, cliffs, and wave-cut platforms.

Just after the Laramide orogeny, the Rockies were like Tibet: a high plateau, probably above sea level. In the last sixty million years, erosion stripped away the high rocks, revealing the ancestral rocks beneath, and forming the current landscape of the Rockies. Periods of glaciation occurred from the Pleistocene Epoch (1.8 million – 70,000 years ago) to the Holocene Epoch (fewer than 11,000 years ago). These ice ages left their mark on the Rockies, forming extensive glacial landforms, such as U-shaped valleys and cirques.

Landscaping an elementary school courtyard in the city of Kuching Landscaping refers to any activity that modifies the visible features of an area of land, including: # living elements, such as flora or fauna; or what is commonly called gardening, the art and craft of growing plants with a goal of creating a beauty within the landscape. # natural elements such as landforms, terrain shape and elevation, or bodies of water; and # abstract elements such as the weather and lighting conditions. Landscaping requires expertise in horticulture and artistic design.

It lies between the two giant impact basins on Mars: Argyre and Hellas. The Noachis quadrangle includes Noachis Terra and the western part of Hellas Planitia. Noachis is so densely covered with impact craters that it is considered among the oldest landforms on Mars—hence the term "Noachian" for one of the earliest time periods in martian history. In addition, many previously buried craters are now coming to the surface, where Noachis' extreme age has allowed ancient craters to be filled, and once again newly exposed.

North of the divide, the margins of prior glaciations give way to much gentler permafrost landforms that escaped glaciation, with ice margin formations such as pingos, moraines, ice-wedge, polygons and frost mounds. The Park protects diverse flora and fauna, including five big game species Dall's sheep, two species of caribou, moose, black bears, grizzly bears, and numerous smaller mammals. The Park is also a birders' delight, with about 150 bird species having been identified. Conservation efforts began in 1972 when scientists identified two sensitive sites.

Further south, in coastal landscapes of the Laurentian Great Lakes, niveo-aeolian deposition facilitates the transport of sand into lakes and marshes, thus enhancing the sand signal. The prolonged denivation process also creates a source of fresh water, in the otherwise extremely dry dune and beach environment, for months after all surface snow has melted. Cryo-aeolian deposition has been proposed as one explanation for certain landforms on the planet Mars. In particular, denivation has been suggested as a cause of apparent meltwater fans in Kaiser Crater.

Excluding the shoreline of Poole Harbour, the Dorset coastline is long Dorset County Council and faces the English Channel. It stretches from Lyme Regis in the west to Highcliffe in the east. The main settlements on the coastline are, from west to east, Lyme Regis, Weymouth, Swanage, Poole, Bournemouth and Christchurch, although the majority of the coastline is not covered by urban development. The Dorset coastline contains a great variety of coastal landforms, including cliffs, bays, headlands, a large natural harbour and a barrier beach.

The Iwokrama Forest is nearly of central Guyana located in the heart of the Guiana Shield, one of the four last pristine tropical forests in the world (Congo, New Guinea, and the Amazon rainforest are the others). It represents an important transition zone in rainfall, landforms, human histories and biological communities. At its widest, the area is , and the greatest extent in a north-south direction is 80 km (50 mi). The Georgetown–Lethem Road dissects the forest, traversing about between the northeastern and southern boundaries.

The interior is a large plateau with irregular landforms. Near Carmen, the Chocolate Hills are more than 1,200 uniformly cone-shaped hills named for the grass growing on the hills that turns brown in the summer, making the landscape look like chocolate mounds. They are hills made of limestone left over from coral reefs during the Ice Age when the island was submerged. The Chocolate Hills are considered one of Philippine's natural wonders and Bohol is often referred to as the Jewel of the Philippines.

Protalus ramparts may be distinguished from glacial moraines by their lack of rock fragments with glacial abrasion or striations. The morphology of the site may also suggest it being unfavourable for the development of a glacier, but suitable for this mechanism.Shakesby, R. 2002 Classic Landforms of the Brecon Beacons, Geographical Association pp14-15 Protalus ramparts are recorded in the Cairngorms and northwest Highlands of Scotland. An especially large example on the north side of Baosbheinn measures 1 km in length and reaches a height of 55 m.

The archipelago's landforms and climate significantly influenced agriculture and trade, and the formation of states. The boundaries of the state of Indonesia represent the 20th century borders of the Dutch East Indies. Fossilised remains of Homo erectus and his tools, popularly known as the "Java Man", suggest the Indonesian archipelago was inhabited by at least 1.5 million years ago. Austronesian people, who form the majority of the modern population, are thought to have originally been from Taiwan and arrived in Indonesia around 2000 BCE.

It had always been assumed to be an alluvial fan, built up by numerous floods and debris small flows. New research demonstrates that a lost mountain could have existed above the head of Plawenntal, with a summit at about 3,100m - the present highest peak on the perimeter being the Mittereck, 2,908 m. There are indications all around the perimeter of a catastrophic collapse, severing former ridges and valley heads (notably Vivanatal). The shape of the lost mountain can readily be reconstructed by projecting these truncated landforms until they meet up.

Mulga (Acacia aneura) The park is located in the Mulga Lands Bioregion which extends from north western NSW into south western Queensland, and contains a range of landforms, each of which supports unique vegetation communities and ecosystems. The predominant vegetation type of this bioregion is dominated by mulga (Acacia aneura) and other woody shrub species. The bioregion also includes the floodplains of the Paroo and Warrego Rivers. The climate of the region is described as arid with low average rainfall which is highly variabile leading to extended droughts and occasional flooding rains.

Schematic illustration of regional denudation for felsic alkaline intrusive rock bodies of the State of Rio de Janeiro, Brazil: Cabo Frio Island and Itaúna Body. In geology, denudation involves the processes that cause the wearing away of the Earth's surface by moving water, by ice, by wind and by waves, leading to a reduction in elevation and in relief of landforms and of landscapes. Endogenous processes such as volcanoes, earthquakes, and plate tectonics uplift and expose continental crust to the exogenous processes of weathering, of erosion, and of mass wasting.

Subsidiary summits in the massif include the high Cerro Carvinto southwest of Sillajhuay, the Cerro Picavilque west-northwest of Sillajhuay, high Cerro Irpa southeast, Cerro Candelaria due east and Morro Chuncaron and Alto Totoni northeast. Generally, the massif is elongated northeastwards and its summit region is poorly accessible. Above elevation, glaciation has eroded the massif and thus the volcano is heavily degraded with no recognizable craters; below that elevation volcanic landforms are more clearly expressed. The volcano was the source of thick lava flows that reached lengths of about and valleys occur all around it.

Since names were, generally, repeatedly applied in Roman families -- even to the point of having several sons with the same nomen but differing cognomina -- it remains plausible that an earlier Pontius inspired the name. It is not known if this is the same name as Ponza or a similar name. Also, Pontia means "Land of Bridges" in Latin, a name which could have been applied for Ponza's many naturally occurring arches and bridge-like landforms. Another theory is that the name is of Greek origin, from Greek pontos, πόντος, sea (see also Pontus).

The geographical landforms of the area include Amador Valley (named after José Maria Amador), Livermore Valley (named after Robert Livermore), Sunol Valley (named after Antonio Suñol), Alamo Valley, and Tassajara Valley. Arroyo de la Laguna is the major waterway which flows south from Amador Valley into Alameda Creek. Arroyo Valle and Arroyo Mocho feed the Laguna from the mountains to the east. José Maria Amador was one of the first Spanish settlers to Murray township in 1835, and the town of Amador, which became Dublin, developed from his property.

There is general agreement that the rocks in the Blue Ridge are the oldest rocks in the state, some being formed at least 1.8 billion years ago. The landforms in Virginia are part of five provinces—the Appalachian Plateau, Ridge and Valley, Blue Ridge, Piedmont and Coastal plain. The Glenwood Cluster is located in the Blue Ridge Province, with the Piedmont Province to the east and the Ridge and Valley to the west. The Blue Ridge, the easternmost of the Appalachian Mountains, extends from Georgia to Pennsylvania, with widths ranging from .

Easterbrook, Don J., Surface Processes and Landforms, 2nd Edition, Prentice-Hall Inc., 1999 When the amount of strain (deformation) is proportional to the stress being applied, ice will act as an elastic solid. Ice will not flow until it has reached a thickness of 30 meters (98 ft), but after 50 meters (164 ft), small amounts of stress can result in a large amount of strain, causing the deformation to become a plastic flow rather than elastic. At this point the glacier will begin to deform under its own weight and flow across the landscape.

The reaction of acid with carbonates, most commonly found as the polymorph calcite and aragonite (CaCO3), relates to the dissolution and precipitation of the mineral, which is a key in the formation of limestone caves, features within them such as stalactite and stalagmites, and karst landforms. Carbonates are most often formed as biogenic or chemical sediments in marine environments. The carbonate group is structurally a triangle, where a central C4+ cation is surrounded by three O2− anions; different groups of minerals form from different arrangements of these triangles., p.

There are five criteria on which a candidate ANSI is evaluated. Representation and condition are assessed at the landscape level, and diversity, ecological functions, and special feature are applied to each site. The representative features for an ANSI in an ecodistrict are the geologic themes for an Earth Science ANSI or the landforms and vegetation for a Life Science ANSI. The diversity of such representative features deemed to be high quality for the site is also important, as those with greater heterogeneity support a greater breadth of species.

Coastal barriers are landscape features that protect the mainland, lagoons, wetlands and salt marshes from the full force of wind, wave and tidal energy. “Undeveloped coastal barriers” are defined by the CBRA to include barrier islands, bars, spits, and tombolos, along with associated aquatic habitats, such as adjacent estuaries and wetlands. Composed of sand and other loose sediments, these elongated, narrow landforms are dynamic ecosystems and are vulnerable to hurricane damage and shoreline recession. Coastal barriers also provide important habitat for a variety of wildlife, and are an important recreational resource.

Features of a glacial landscape Before glaciation, mountain valleys have a characteristic "V" shape, produced by eroding water. During glaciation, these valleys are often widened, deepened and smoothed to form a "U"-shaped glacial valley or glacial trough, as it is sometimes called. Glacial Landforms: Trough The erosion that creates glacial valleys truncates any spurs of rock or earth that may have earlier extended across the valley, creating broadly triangular-shaped cliffs called truncated spurs. Within glacial valleys, depressions created by plucking and abrasion can be filled by lakes, called paternoster lakes.

Shoalwater Bay contains landforms of undisturbed depositional sequences resulting from the action of wind (dunes) and water (beach ridges). These dune systems are of great significance in the understanding the evolution of aeolian dunes in eastern Australia during the Quaternary. These dune systems differ from other coastal and island sand masses in Queensland in that they demonstrate fewer episodes of instability and contain a much lower number of perched lakes. The old beach ridges and terraces in the Clinton Lowlands portion of the place are important for understanding coastline evolution in the last 6000 years.

Since the beginning of the Quaternary, 2.6 million years ago, the uplands of North Wales have been subject to several phases of glaciation. The Aber valley provides physical evidence of the two most recent phases of glaciation which occurred between about 28,000-16,000 and 12,970 - 11,770 years ago. The Carneddau have a notable range of glacial and periglacial features that have been studied by geologists, including Charles Darwin, for well over a century, and plays a key role not only into research into landforms, but also into climate change and vegetation history.

Long after the lake dried up, Spaniards report that Pueblo Indians traded with salt from the lake basin. Evidence of the existence of former lakes in the Estancia Valley was first reported in 1903. Drill cores in lake sediments, landforms formed on the former shoreline and outcrops have yielded evidence of the basin's history, going back to the Illinoian glaciation. The paleoclimatic record of Lake Estancia is the best-studied in New Mexico, although different conclusions about precipitation and temperature during the ice age have been drawn from it.

There are of gardens. By siting the homestead along the top of a ridge it was natural that it be the centerpiece of the landscaped setting reinforced by the landforms. The garden display and recreation areas are arranged to the tree main elevations of the house while the more utilitarian garden areas are set further out to the east or south- east. The garden design is structured to provide a landscaped setting for the important elevations of the homestead as well as giving garden views from each room of the main wing of the house.

Summer temperatures at the Ubehebe Craters can be quite high while winter temperatures often fall below freezing. During the Little Ice Age, temperatures were low enough to allow the development of snow patches in the Ubehebe Craters, which then left nivation landforms. Present-day precipitation in Death Valley is about with large year-to-year variability but was higher during past pluvial periods such as between 17,500 and 15,000 years ago. Today, precipitation usually occurs in the form of sudden rainfall that can trigger substantial erosion and sometimes generates ephemeral lakes in the craters.

Most known blockfields are located in the northern hemisphere. Examples can be found in Abisko National Park in Sweden, Snowdonia National Park in Wales, the Great End-Scafell Pike ridge in England and Hickory Run Boulder Field and River of Rocks in the Appalachian Mountains of the United States. All examples except the first one are outside present day subpolar climate areas, and have thus traditionally been seen as relict landforms from past times when these areas were under periglaciation. The term "felsenmeer" comes from the German meaning 'sea of rock'.

The bogs - waterlogged peat accumulations - fall in type between basin mires and blanket bogs, and are an important factor in the significance of the site on their own account, as they transition to other landforms, and because they are the easternmost examples in Britain of such habitats. Bog sites on the moors give rise to heather, cross-leaved heath, common and hare’s-tail cotton-grasses (Eriophorum angustifolium and E. vaginatum) amongst a variety of bog-mosses including (Sphagnum papillosum), (S. capillifolium) and (S. magellanicum). Less common are crowberry (Empetrum nigrum ssp.

G., The Placenames of Pembrokeshire, National Library of Wales, Aberystwyth, 1992, , p 347 The Cuch valley is the most prominent valley among the low foothills which lie between the Preseli Hills and Cambrian Mountains, and Emlyn is essentially the region north of, and within, the gap between these landforms. As such, it was the first part of Dyfed to face invaders from Ceredigion. Its area was about .

There are a variety of applications of GIS and remote sensing data in water management, ranging from exploration, modeling of subsurface flow and natural recharge, pollution control and hydrogeologic process monitoring. In essence, the topography, vegetation cover, drainage landforms and aquifer types could be inferred from remote sensing data and images from various types of sensors and platform. A case study in Burdur, Turkey presenting the use of remote sensing data and spatial analysis performed by GIS is one of the pioneer projects.Sener, E., Davraz, A., Ozcelik, M. (2007).

Though she was primarily a petrologist, she made astute observations concerning inequalities in erosion in catchments and hence the survival of palaeoforms in the landscape. Although these observations were opposed to one of primary principles of geomorphology at the time, Knopf implied that remnant landforms should still survive for an extended period due to unequal erosion. In 1951, she joined Stanford University in geology department as a research associate. She continued to study the Stissing Mountain rocks until her retirement in 1955 but also made some expeditions to the Rocky Mountains.

On progressively smaller scales, similar ideas apply, where individual landforms evolve in response to the balance of additive processes (uplift and deposition) and subtractive processes (subsidence and erosion). Often, these processes directly affect each other: ice sheets, water, and sediment are all loads that change topography through flexural isostasy. Topography can modify the local climate, for example through orographic precipitation, which in turn modifies the topography by changing the hydrologic regime in which it evolves. Many geomorphologists are particularly interested in the potential for feedbacks between climate and tectonics, mediated by geomorphic processes.

Glacial erosion is responsible for U-shaped valleys, as opposed to the V-shaped valleys of fluvial origin.Bennett, M.R. & Glasser, N.F., 1996, Glacial Geology: Ice Sheets and Landforms, John Wiley & Sons Ltd, 364 p. . The way glacial processes interact with other landscape elements, particularly hillslope and fluvial processes, is an important aspect of Plio-Pleistocene landscape evolution and its sedimentary record in many high mountain environments. Environments that have been relatively recently glaciated but are no longer may still show elevated landscape change rates compared to those that have never been glaciated.

The Duncan House in Castlecrag is historically significant as one of Walter Burley Griffin's designed houses constructed of local stone and knitlock concrete. The Griffin-conceived Castlecrag area subdivision is historically significant at state level for its innovative goal of working with natural landforms and flora rather than against them. The estate left a legacy of four miles of conserved harbouside foreshore in the Willoughby Local Government area. The estate is historically significant as the home of Walter Burley Griffin and Marion Mahony Griffin who lived there approximately 1924-1936.

Turner, A. (2006) Geomorphometrics: ideas for generation and use. CCG Working Paper, Version 0.3.1 [online] Centre for Computational Geography, University of Leeds, UK; Accessed 7 May 2007 In simple terms, geomorphometry aims at extracting (land) surface parameters (morphometric, hydrological, climatic etc.) and objects (watersheds, stream networks, landforms etc.) using input digital land surface model (also known as digital elevation model, DEM) and parameterization software. Extracted surface parameters and objects can then be used, for example, to improve mapping and modelling of soils, vegetation, land use, geomorphological and geological features and similar.

Kerry E. Sieh is an American geologist and seismologist. Sieh's principal research interest is earthquake geology, which uses geological layers and landforms to understand the geometries of active faults, the earthquakes they generate, and the crustal structure their movements produce. His early work on the San Andreas fault led to the discovery of how often and how regularly it produces large earthquakes in southern California. Sieh received his undergraduate degree in geology from the University of California, Riverside in 1972 and his Ph.D. degree in geology from Stanford University in 1977.

The park centers on the Khvalanskyaya ridge, a raised plateau that stretches along the west bank of the Volga River (referred to as the 'Right Bank'). Because the bedrock is primarily chalk and marl, the landform reflects extensive erosion out from the center of the ridge, with undulating and hilly terrain and numerous interconnected ravines and gullies. The varied landforms create many micro- climates and habitats. The highest mountain (Belenkaya, almost entirely of chalk) is 369 meters in altitude, and there are five other mountains over 250 meters in height.

Tambroso is the name of a Portuguese mountain located in the civil parish of Ribeirinha, in the municipality of Horta, on the island of Faial of the Azores. The mountain and its surrounding landforms is geographically close to the volcano in the center of ilha do Faial, of which the peak is a part. The whole system has a maximum elevation at Cabeço Gordo, which is above sea level. Tambroso itself reaches above sea-level and is near Alto da Pedreira, another local peak, and the town of Ribeirinha.

Late Pleistocene to Early Holocen Glacial Landforms of Yushan Area, Taiwan As recently as seventeen thousand years ago, permanent ice caps existed throughout Taiwan's highest mountains and extended owing to the wet climate down to ; whereas currently, the nearest glaciers to the Tropic of Cancer are in Mexico on the Iztaccíhuatl volcano. The ocean waters off Taiwan's east coast are deep; in fact, submarine slopes plunge down to the Pacific Ocean at a grade of 1:10 and the ocean reaches a depth of more than about from the coast.Central Geological Survey, MOEA.

Vernacular geography is the sense of place that is revealed in ordinary people's language. Current research by the Ordnance Survey is attempting to understand the landmarks, streets, open spaces, water bodies, landforms, fields, woods, and many other topological features. These commonly used descriptive terms do not necessarily use the official or current names for features; and often these concepts of places don't have clear, rigid boundaries. For example, sometimes the same name may refer to more than one feature, and sometimes people in a locality use more than one name for the same feature.

Three kinds of streams are formed by headward erosion: insequent streams, subsequent streams, and obsequent and resequent streams (See Fluvial landforms of streams.) Insequent streams form by random headward erosion, usually from sheetflow of water over the landform surface. The water collects in channels where the velocity and erosional power increase, cutting into and extending the heads of gullies. Subsequent streams form by selective headward erosion by cutting away at less resistive rocks in the terrain. Obsequent and resequent streams form after time in an area of insequent or subsequent streams.

Ravel Peak () is an isolated peak, rising to about 1,300 m, surmounting Debussy Heights situated in the northern portion of Alexander Island, Antarctica. The peak is markedly pyramid shaped when viewed from the east side. First mapped from air photos taken by the Ronne Antarctic Research Expedition (RARE), 1947–48, by Searle of the Falkland Islands Dependencies Survey (FIDS) in 1960. Named by the United Kingdom Antarctic Place-Names Committee (UK-APC) after Maurice Ravel (1875–1937), French composer and in association with the nearby landforms named after composers in this area.

When wind flow enters a saucer shape blowout, the wind speed decreases upon entering the blowout and accelerates at the downwind side of the formation. A zone of separation develops along the lee slope as the wind enters the blowout and decrease in speed, yet it accelerates again as it re-attaches at the basin and flow up to the depositional lobe, where sand becomes evacuated.Hugenholtz, Chris H, and Stephen A. Wolfe. “Form-flow Interactions of an Aeolian Saucer Blowout.” Earth Surface Processes and Landforms, 34 (2009): 919-928.

It is a key place along the songline believed to be created by the travels of creation beings, Baiame, Bootha and Daramulan. It is an important part of the sacred story of the earths' creation, including the coming into being of Daramulan and the handing down of Aboriginal lore to Aboriginal people over generations. Much of the symbolism of the engravings, stone arrangements, landforms and vegetation of the site has been identified as being associated with secret women's business. This is of social significance at a state level for Aboriginal women.

Much of the symbolism of the engravings, stone arrangements, landforms and vegetation of the site has been identified as being associated with secret women's business. For Aboriginal people of south east Australia gendered cultural divisions traditionally pervade broad areas of community life ranging from practical hunting and fishing practises to spiritual matters, according to cultural law. Aboriginal cultural law (sometimes referred to as traditional law or customary law) refers to the rules of acceptable and unacceptable behaviour in traditional Aboriginal communities. It refers to the rules for living, established by ancestral beings during the Dreaming.

The influences that biotic factors have on the way landforms are developed. There has been much work on these approaches such as; the effect that parent material has on the distribution of plants, the increase of precipitation due to an influx of transpiration, the stability of a hillslope due to the abundance of vegetation or, the increase of sedimentation due to a beaver dam. Biogeomorphology shows the axiomatic relationship between certain land forming processes and biotic factors. That is, certain geomorphic processes shape the biota and biotic factors can shape land forming processes.

Arctic Char caught on Tree River in July 1996 by John MacKay The Tree River (Kogluktualuk) is a river in Nunavut, Canada. It flows into Coronation Gulf, an arm of the Arctic Ocean. Glacial landforms, such as a kame delta, are represented in the area of the Tree River. This area was the ancestral home of several Copper Inuit bands, including the Kogluktualugmiut (also known as Utkusiksaligmiut), who lived along its shores; the Pingangnaktogmiut, who lived west of the river; and the Nagyuktogmiut (also known as Killinermiut), who lived east of Tree River.

Landforms surrounding the barn and upper Jefferson River valley The Panic of 1893 caused financial hardship for the Doncaster operation. Armstrong sold the ranch to Max Lauterbach and left Montana in 1900. From there, the barn was owned by a number of different people, and fell into disrepair until purchased by the Bayers family, who owned the Doncaster Farm property from 1933 until 1997. Arthur and Elizabeth Bayers raised Hereford cattle and were major breeders who sold their stock all over North America and held a cattle sale every year in the barn.

The volcanic complex has shaped the local landscape and produced a huge variety of volcanic landforms and products over the last 300,000 years. Cinder cones, lava domes, calderas and craters can be found in the area apart from the widest variety of volcanic rocks in all the Southern Zone, for example both primitive basalts and rhyolites. Cordón Caulle erupted shortly after the 1960 Valdivia earthquake, the largest recorded earthquake in history. Apart from this, the Puyehue-Cordón Caulle area is one of the main sites of exploration for geothermal power in Chile.

The materials left over after the rock breaks down combined with organic material creates soil. The mineral content of the soil is determined by the parent material; thus, a soil derived from a single rock type can often be deficient in one or more minerals needed for good fertility, while a soil weathered from a mix of rock types (as in glacial, aeolian or alluvial sediments) often makes more fertile soil. In addition, many of Earth's landforms and landscapes are the result of weathering processes combined with erosion and re-deposition.

This desert climate is in part due to a rain shadow effect caused by the Cascade Range. Pine and juniper forests cover 35% of Eastern Oregon, much in the mountains that include the Blue Mountains, Strawberry Mountains, Wallowa Mountains, Trout Creek Mountains, Ochoco Mountains, and Steens Mountain. Volcanic basalt flows from the Columbia River Basalt Group covered large sections of Eastern Oregon 6 to 17 million years ago. Other landforms include the Alvord Desert, Owyhee Desert, Warner Valley, Deschutes River, Owyhee River, Grande Ronde River, Joseph Canyon, The Honeycombs, and Malheur Butte.

Phytogeomorphology is the study of how terrain features affect plant growth.Howard, J.A., Mitchell, C.W., 1985. Phytogeomorphology. Wiley. It was the subject of a treatise by Howard and Mitchell in 1985, who were considering the growth and varietal temporal and spatial variability found in forests, but recognized that their work also had application to farming, and the relatively new science (at that time) of precision agriculture. The premise of Howard and Mitchell is that landforms, or features of the land's 3D topography significantly affect how and where plants (or trees in their case) grow.

Where a geological region contains more than one plain, they may be connected by a pass (sometimes termed a gap). Coastal plains would mostly rise from sea level until they run into elevated features such as mountains or plateaus. Plains are one of the major landforms on earth, where they are present on all continents, and would cover more than one-third of the world's land area. Plains may have been formed from flowing lava, deposited by water, ice, wind, or formed by erosion by these agents from hills and mountains.

There are several different landforms in the park that have taken millions of years to form, and give it a diversity not seen in any other national park in Canada. Sediment left by an ancient inland sea 500-200 million years ago had since become pressed into layers of rock. These layers were stacked about deep and are peppered with fossils, remnants of these ancient sea beds. As the continents shifted, the North American and Pacific Plates collided, the force of which pushed the layers of rock upwards.

The boundary of the Important Bird Area (IBA) is defined by the boundaries of pastoral leases containing sites at which the grasswrens have been recorded. The Buckley River, a major tributary of the Georgina River system of the Lake Eyre Basin, runs through the central parts of the IBA and has its source within it. Some 95% of the site is within cattle stations, about 80% is covered by mineral exploration leases, and about 5% is subject to active mining leases. Landforms include gently undulating plains and low hills.

Rhos Llawr Cwrt National Nature Reserve nestles in the base of the Clettwr valley, some 10 kilometres from the Ceredigion coast, between Ffostrasol and Talgarreg. Glaciers have scraped and shaped this landscape and evidence of the last Ice Age can be seen everywhere. The most striking of these are the remains of the pingos found on the reserve, landforms which were once small hills but whose summits collapsed when the ice which formed them melted. The site carries international importance because it holds one of the best populations of the marsh fritillary butterfly in Wales.

The mountain range stretches from the valley of the river Timok in the west to Cape Emine at the Black Sea coast in the east, spanning a length of 555 km and width between 20 and 70 km. The Balkan Mountains are divided into western, central and eastern part by the Zlatitsa and Vratnik Passes. The range is highest in its central part, which includes Botev Peak at 2,376 m; the altitude drops slowly to the east until it reaches the sea. The relief is varied, with many mountain passes, gorges and landforms.

The summits are rounded and there are also the remnants of plateaux and -like landforms. Geologically the clearest division is also between east and west. Large areas of the eastern Black Forest, the lowest layer of the South German Scarplands composed of Bunter Sandstone, are covered by seemingly endless coniferous forest with their island clearings. The exposed basement in the west, predominantly made up of metamorphic rocks and granites, was, despite its rugged topography, easier to settle and appears much more open and inviting today with its varied meadow valleys.

When this obliquity is high, its poles get much more direct sunlight and heat; this causes the ice caps to warm and become smaller as ice sublimes. Adding to the variability of the climate, the eccentricity of the orbit of Mars changes twice as much as Earth's eccentricity. As the poles sublime, the ice is redeposited closer to the equator, which receive somewhat less solar insolation at these high obliquities. Computer simulations have shown that a 45° tilt of the Martian axis would result in ice accumulation in areas that display glacial landforms.

The Jornada del Muerto Desert ecoregion, in the Deserts and xeric shrublands Biome, is a wide and long stretch of flat desert landforms and xeric habitat about from north to south. The desert runs between the Oscura Mountains and San Andres Mountains on the east, and the Fra Cristóbal Range and Caballo Mountains on the west. The western mountains block access to the Rio Grande, the most reliable water source in the region. The Jornada del Muerto Desert remains almost entirely uninhabited and undeveloped to the present day.

They found the sequence in the cliff below St. Helens, then just to the east at Siccar Point found what Hutton called "a beautiful picture of this junction washed bare by the sea". Continuing along the coast, they made more discoveries including sections of the vertical beds showing strong ripple marks which gave Hutton "great satisfaction" as a confirmation of his supposition that these beds had been laid horizontally in water.

Mountain summits were marked by vertical rods, their heights exaggerated five times relative to the horizontal scale to increase the visual effect. This was a standard traditionally adopted for British military terrain maps. The topography was then finished off by manually sculpting the landforms according to the contours shown on the Bartholomew maps. After the last visit of the Polish cartographers in 1977, hotel employees and members of the Tomasik family continued to work on the map intermittently over two more summers before it was completed in 1979.

Two of the most notable are the Avenida de Mayo and the Plaza de Mayo in Buenos Aires, near the location of the Cabildo. The May Pyramid was erected in the Plaza a year after the revolution, and was rebuilt in its present form in 1856. Veinticinco de Mayo ("May 25") is the name of several administrative divisions, cities, public spaces and landforms of Argentina. There are departments of this name in the provinces of Chaco, Misiones, San Juan, Rio Negro and Buenos Aires, the latter holding the town of Veinticinco de Mayo.

The Musgrave Block is currently passive geologically, with surficial processes described as residual erosion. The area currently experiences on average less than 150mm (6 inches) of rainfall per annum, which provides little surface runoff and hence virtually no erosion. The landforms of the area are primarily composed of wide calcrete plains, often covered by Pleistocene Age aeolian deposits of sand dunes, sometimes reworked into ephemeral sheetwash fans. Outcrop is rare, restricted primarily to the igneous rocks of the Giles Complex and several granite domes, gneiss domes and isolated outcrops.

Guinevere Planitia is an expansive lowland region of Venus that lies east of Beta Regio and west of Eistla Regio (quadrangle V-30). These low-lying plains, particularly in the western portion, are characterized by apparent volcanic source vents and broad regions of bright, dark, and mottled deposits. They are the only break in an equatorially connected zone of highlands and tectonic zones. The types, numbers, and patterns of mapped tectonic features and small volcanic landforms in the region provide important detail in the interpretation and evolution of venusian landscape.

According to the United States Geological Survey, Reelfoot Lake was formed in northwestern Tennessee when the region subsided during the 1811–12 New Madrid earthquakes, which were centered around New Madrid, Missouri. The earthquakes resulted in several major changes in the landforms over a widespread area, with shocks being felt as far away as Quebec, Canada. A land survey begun by Henry Rutherford in 1785 identified the existent waterway as the Reel Foot River. The now extinct river flowed into the Mississippi River prior to the earthquakes of 1811 and 1812.

Relationships are interpreted between landform development, current and past geologic processes, ground and surface water, and the strength characteristics of soil and rock. Processes evaluated include both surficial processes (for example, slope, fluvial, and coastal processes), and deep-seated processes (for example, volcanic activity and seismicity). Geotechnical zones or domains are designated based on soil and rocked geological strength characteristics, common landforms, related geologic processes, or other pertinent factors. Proposed developmental modifications are evaluated and, where appropriate, analyzed to predict potential or likely changes in types and rates of surficial geologic processes.

Some impact craters are present, but Venus is similar to Earth in that there are fewer craters than on the other rocky planets that are largely covered by them. This is due in part to the thickness of the Venusian atmosphere disrupting small impactors before they strike the ground, but the paucity of large craters may be due to volcanic re- surfacing, possibly of a catastrophic nature. Volcanism appears to be the dominant agent of geological change on Venus. Some of the volcanic landforms appear to be unique to the planet.
|
|
These may be caused by mantle convection. Many of the tectonic features such as tesserae (large regions of highly deformed terrain, folded and fractured in two or three dimensions), and arachnoids (for those features resembling a spider's web) are associated with volcanism. Eolian landforms are not widespread on the planet's surface, but there is considerable evidence the planet's atmosphere causes the chemical weathering of rock, especially at high elevations. The planet is remarkably dry, with only a chemical trace of water vapor (20 ppm) in the Venusian atmosphere.

No landforms indicative of past water or ice are visible in radar images of the surface. The atmosphere shows isotopic evidence of having been stripped of volatile elements by offgassing and solar wind erosion over time, implying the possibility that Venus may have had liquid water at some point in the distant past; no direct evidence for this has been found. Much speculation about the geological history of Venus continues today. The surface of Venus is not easily accessible because of the extremely thick atmosphere (some 90 times that of Earth's) and the surface temperature.

Kit-Mikayi, a celebrated tor near Kisumu, Kenya Tors are landforms created by the erosion and weathering of rock; most commonly granites, but also schists, dacites, dolerites, ignimbrites, coarse sandstones and others. Tors are mostly less than high. Many hypotheses have been proposed to explain their origin and this remains a topic of discussion among geologists and geomorphologists, and physical geographers. It is considered likely that tors were created by geomorphic processes that differed widely in type and duration according to regional and local differences in climate and rock types.

Landforms visible on Mars strongly suggest that liquid water has existed on the planet's surface. Huge linear swathes of scoured ground, known as outflow channels, cut across the surface in about 25 places. These are thought to be a record of erosion caused by the catastrophic release of water from subsurface aquifers, though some of these structures have been hypothesized to result from the action of glaciers or lava. One of the larger examples, Ma'adim Vallis is long, much greater than the Grand Canyon, with a width of and a depth of in places.

New England's long rolling hills, mountains, and jagged coastline are glacial landforms resulting from the retreat of ice sheets approximately 18,000 years ago, during the last glacial period. New England is geologically a part of the New England province, an exotic terrane region consisting of the Appalachian Mountains, the New England highlands and the seaboard lowlands. The Appalachian Mountains roughly follow the border between New England and New York. The Berkshires in Massachusetts and Connecticut, and the Green Mountains in Vermont, as well as the Taconic Mountains, form a spine of Precambrian rock.

Areas surrounded by mountain barriers, like some parts of Sonoma and Napa counties will be warmer due to the lack of this cooling influence. The soil types and landforms of California vary greatly, having been influenced by the plate tectonics of the North American and Pacific Plates. In some areas the soils can be so diverse that vineyards will establish blocks of the same vine variety planted on different soils for purpose of identifying different blending components. This diversity is one of the reasons why California has so many different and distinct American Viticultural Areas.

The name "Groenland" was given by early European colonists to both the mountains, and to the surrounding area. Meaning "Greenland" in Dutch, it refers to the lush green vegetation of the mountain and its surrounds (Although the name is also the Dutch language term for the island of Greenland in the north Atlantic, the two toponyms were coined independently of each other). The original indigenous Chainoqua names for the area's landforms are unfortunately not well recorded. The low-lying region to the south, acquired the name "Elgin", after its historic railway station.

London: Methuen, p. 32. . is part of a succession of ice age geological landforms, known as a glacial series. It is a hollow that is left behind by the ice mass, as the snout of the glacier (German: Gletscherzunge) recedes, which initially fills with meltwater, forming a proglacial lake, and later may be filled with surface water from streams or precipitation. When the glacier has more fully retreated this produces a finger lake or glacial piedmont lake (German: Zungenbeckensee, known as a Gletscherendsee of the glacial series in the Alpine Foreland).

It is distributed under licence by the BBC in other countries, Discovery Channel for North America, ZDF for Germany, Antena 3 for Spain and Skai TV for Greece. The seven-part series focuses on life and the environment in both the Arctic and Antarctic. The production team were keen to film a comprehensive record of the natural history of the polar regions because climate change is affecting landforms such as glaciers, ice shelves, and the extent of sea ice. The film was met with critical acclaim and holds a Metacritic score of 90/100.

Characteristic landforms caused by groundwater sapping are “theater-shaped” channel heads and “U-shaped” valleys, which have a consistent width and steep valley walls. Weakened basal rocks are unable to support more resistant upper layers, causing valley head and sidewalls to collapse inwards. Theater-shaped channel heads are characterized by overhanging sidewalls that are relatively dry compared to the lower level rocks below the zone of seepage. The development of theater heads has been related to “ground-water flow direction, jointing and faulting, permeability contrasts, formation slope and dip angles, and formation cohesion”.

The geology of Estonia is the study of rocks, minerals, water, landforms and geologic history in Estonia. The crust is part of the East European Craton and formed beginning in the Paleoproterozoic nearly two billion years ago. Shallow marine environments predominated in Estonia, producing extensive natural resources from organic matter such as oil shale and phosphorite. The Mesozoic and much of the Cenozoic are not well-preserved in the rock record, although the glaciations during the Pleistocene buried deep valleys in sediment, rechanneled streams and left a landscape of extensive lakes and peat bogs.

Estonian geologists have developed The Book of Primeval Nature, chronicling landforms in the country. The Kaali meteorite crater on Saaremaa Island was the first geologic site slated for protection after its recognition in 1937. The Institute of Geology of the Academy of Sciences was organized in 1947, followed by the founding of the Geological Survey of Estonia and the Institute of Geology in 1957. Since the 1950s, Estonian organizations drilled tens of thousands of boreholes through the sedimentary cover, in some cases reaching more than 500 meters deep into the crystalline basement rock.

Richard Serra's East-West/West-East installation in the Zekreet Peninsula The Zekreet Peninsula, also known as the Abrouq Peninsula, is a peninsula in western Qatar, located to the north of the industrial city of Dukhan. Much of the area is associated with erosional landforms such as foothills, mesas and gypsum plateaux. The village of Zekreet, the Zekreet Film City, and the headland of Ras Abrouq (which includes a nature reserve for wild deer) are all found on this stretch of land. The peninsula is part of the Al Reem Biosphere Reserve.

Palsas (heaving of organics-rich soils in discontinuous permafrost) may be found in alpine areas below Mugi Hill on Mount Kenya. Frost heaving creates raised-soil landforms in various geometries, including circles, polygons and stripes, which may be described as palsas in soils that are rich in organic matter, such as peat, or lithalsa in more mineral-rich soils. The stony lithalsa (heaved mounds) found on the archipelago of Svalbard are an example. Frost heaves occur in alpine regions, even near the equator, as illustrated by palsas on Mount Kenya.

The Dorset section has yielded important fossils, including Jurassic trees and the first complete Ichthyosaur, discovered near Lyme Regis in 1811 by Mary Anning. The county features some notable coastal landforms, including examples of a cove (Lulworth Cove), a natural arch (Durdle Door) and chalk stacks (Old Harry Rocks). Jutting out into the English Channel at roughly the midpoint of the Dorset coastline is the Isle of Portland, a limestone island that is connected to the mainland by Chesil Beach, a long shingle barrier beach protecting Britain's largest tidal lagoon.Chaffey (pp.

The diversity of soils and landforms has hardly received any attention although their spatial and temporal variation may produce important quantitative and qualitative changes in the landscape. It is only in the last few years that the term diversity has also caught the attention of scientists working on soils and other fields within the earth sciences which creates a forum and research projects on geodiversity. Measurements of diversity were introduced to pedology few years ago. The concept of pedodiversity is now widely accepted within the soil science community.

Owing to the variety of volcanic landforms, the province was included in the 2010 Tentative List of UNESCO World Heritage Sites and a number of potential geosites have been identified at Payún Matrú itself. The active field is part of the backarc area of the Southern Volcanic Zone, a long volcanic arc and one of four eruptive belts in the Andes; the other three being the Northern Volcanic Zone, the Central Volcanic Zone and the Austral Volcanic Zone. Other volcanoes in the region include the Laguna del Maule, almost due west from Payún Matrú.
|
|
In the westerly part of the volcanic field most precipitation falls during winter under the influence of the Andes, while the eastern part has most precipitation occurring during summer. The higher parts of Payún Matrú may have risen above the snowline during ice ages, and periglacial landforms have been observed. Palynology data from south of the region indicate that the climate has been stable since the Late Pleistocene. The vegetation in the volcanic field is mostly characterized by sparse bushes as well as herbaceous vegetation but few trees, and is classified as xerophytic.

Geology existed as a cloud of isolated, disconnected ideas about rocks, minerals, and landforms long before it became a coherent science. Theophrastus' work on rocks, Peri lithōn, remained authoritative for millennia: its interpretation of fossils was not overturned until after the Scientific Revolution. Chinese polymath Shen Kua (1031–1095) first formulated hypotheses for the process of land formation. Based on his observation of fossils in a geological stratum in a mountain hundreds of miles from the ocean, he deduced that the land was formed by erosion of the mountains and by deposition of silt.

Cape Cod was formed by retreating glaciers Geologic makeup of Cape Cod The bulk of the land on Cape Cod consists of glacial landforms, formed by terminal moraine and outwash plains. This represents the southernmost extent of glacial coverage in southeast New England; similar glacial formations make up Long Island in New York and Block Island in Rhode Island. Together, these formations are known as the Outer Lands, or more obscurely as the "Isles of Stirling". Geologically speaking, Cape Cod is quite young, having been laid down some 16,000 to 20,000 years ago.

Tilted layers of limestone beside the R467 road at Donja Strmica The geology of Bosnia & Herzegovina is the study of rocks, minerals, water, landforms and geologic history in the country. The oldest rocks exposed at or near the surface date to the Paleozoic and the Precambrian geologic history of the region remains poorly understood. Complex assemblages of flysch, ophiolite, mélange and igneous plutons together with thick sedimentary units are a defining characteristic of the Dinaric Alps, also known as the Dinaride Mountains, which dominate much of the country's landscape.

The Firth of Clyde The Highland Boundary Fault runs past Bute and through the northern part of Arran, so from a geological perspective some of the islands are in the Highlands and some in the Central Lowlands.Gillen (2003) p. 28 As a result, Arran is sometimes referred to as "Scotland in miniature" and the island is a popular destination for geologists, who come to see intrusive igneous landforms such as sills and dykes as well as sedimentary and metasedimentary rocks ranging widely in age.McKirdy et al. (2007) pp.

Besides the Olympians, the Greeks also worshipped various local deities. Among these were the goat-legged god Pan (the guardian of shepherds and their flocks), Nymphs (nature spirits associated with particular landforms), Naiads (who dwelled in springs), Dryads (who were spirits of the trees), Nereids (who inhabited the sea), river gods, satyrs (a class of lustful male nature spirits), and others. The dark powers of the underworld were represented by the Erinyes (or Furies), said to pursue those guilty of crimes against blood-relatives. The Greek deities, like those in many other Indo-European traditions, were anthropomorphic.

These wetlands are important not only because they are the habitats of numerous inhabitants such as mammals, birds, fish, amphibians, and invertebrates, but they support the growing of rice and other food crops as well as provide water filtration and protection from storms and flooding. Freshwater lakes such as the Aral Sea in central Asia have also suffered. Once the fourth largest freshwater lake, it has lost more than 58,000 square km of area and vastly increased in salt concentration over the span of three decades. Subsidence, or the gradual sinking of landforms, is another result of water scarcity.

The larger part of the Cheshire Plain is covered by a thick mantle of glacial till and sands and gravels of glacio-fluvial origin. These deposits are the legacy of the over-riding of the area on several occasions by glacial ice during the past 2 million years. The present distribution of deposits and the landforms to which they give rise are largely the result of the last ice age, the Devensian which peaked around 22-20,000 years ago. Kettle holes caused by the in-situ melting of ice-blocks during deglaciation are a notable feature of the landscape.

Winds can shape landforms, via a variety of aeolian processes such as the formation of fertile soils, such as loess, and by erosion. Dust from large deserts can be moved great distances from its source region by the prevailing winds; winds that are accelerated by rough topography and associated with dust outbreaks have been assigned regional names in various parts of the world because of their significant effects on those regions. Wind also affects the spread of wildfires. Winds can disperse seeds from various plants, enabling the survival and dispersal of those plant species, as well as flying insect populations.

Camp Acahela was founded in 1919. The camp is located in the village of Blakeslee, PA on a peninsula formed by the joining of the Lehigh River and the Tobyhanna Creek. The camp has a total area of 242 acres covered by a variety of landforms and vegetation, ranging from heavily wooded ridges and cliffs, to wide open parade fields, to shady groves of ancient fir trees that provide a wide variety of camping opportunities year-round for every type of Scouting unit. From 1919 until 1991 the camp hosted a boy scout summer camp program.

A small percentage of the mammals are non-human primates, used in research for their similarity to humans. Charles Darwin, Jared Diamond and others have noted the importance of domesticated mammals in the Neolithic development of agriculture and of civilization, causing farmers to replace hunter-gatherers around the world. This transition from hunting and gathering to herding flocks and growing crops was a major step in human history. The new agricultural economies, based on domesticated mammals, caused "radical restructuring of human societies, worldwide alterations in biodiversity, and significant changes in the Earth's landforms and its atmosphere... momentous outcomes".

It is a popular day boat-trip for Sitkans or a place to cruise around for fishermen already in the area. St. Lazaria is not supposed to be visited by foot from anyone other than permitted scientists as every square foot of ground contains burrows for nesting birds and can be easily crushed, disturbed, or destroyed. However, over 2,000 people a year visit the island by boat circling around the volcanic hulk -- admiring its birds, cliffs, caves, and other volcanic landforms. Small and large-scale tour operators alike make St. Lazaria a popular and well-known tourist destination in Sitka.

The Big Horn Mountains Wilderness comprise most of the Big Horn's. The desert is bordered east by other mountain foothills on the west border of the Hassayampa River. The Tonopah Desert also lies between two plains: the narrow southeast ridgeline of the Belmont Mountains and the Hassayampa Plain are northeast. The west and southwest of the Tonopah Desert is connected to the southeast section of the large Harquahala Plain, northwest-southeast trending, the same lineage as the Centennial and Bouse Washes which drain the named plains, mountains, and the desert, (about twenty landforms in the region).

Diagram showing how closed system (hydrostatic) pingos are formed Closed systems, also known as hydrostatic pingos are formed as a result of hydrostatic pressure built up within the core of pingos due to water. They occur in regions of continuous permafrost where there is an impermeable ground layer. These pingos are found in flat, poorly drained areas with limited groundwater available such as shallow lakes and river deltas. The formation of these landforms occurs when layers of permafrost generates an upwards movement of pressure, resulting in masses of confined soil freezing which push material upwards that begins to expand.

Impact craters and structures are dominant landforms on many of the Solar System's solid objects and present the strongest empirical evidence for their frequency and scale. Impact events appear to have played a significant role in the evolution of the Solar System since its formation. Major impact events have significantly shaped Earth's history, and have been implicated in the formation of the Earth–Moon system, the evolutionary history of life, the origin of water on Earth and several mass extinctions. The prehistoric Chicxulub impact, 66 million years ago, is believed to be the cause of the Cretaceous–Paleogene extinction event.

Major impact events have significantly shaped Earth's history, having been implicated in the formation of the Earth–Moon system, the evolutionary history of life, the origin of water on Earth, and several mass extinctions. Impact structures are the result of impact events on solid objects and, as the dominant landforms on many of the System's solid objects, present the most solid evidence of prehistoric events. Notable impact events include the Late Heavy Bombardment, which occurred early in history of the Earth–Moon system, and the Chicxulub impact, 66 million years ago, believed to be the cause of the Cretaceous–Paleogene extinction event.

River Indus and its numerous eastern tributaries of Chenab, Ravi, Sutlej, Jhelum, Beas are spread across most of Punjab. The plain of river Indus continues towards and occupy most of western Sindh. The plains have many fluvial landforms (including bars, flood plains, levees, meanders and ox-bows) that support various natural biomes including tropical and subtropical dry and moist broadleaf forestry as well as tropical and xeric shrublands (deserts of Thal and Cholistan in Punjab, Nara and Thar in Sindh). The banks and stream beds of the river system also support riparian woodlands that exhibit the tree species of kikar, mulberry and sheesham.

Seven types of wattle were seen blooming at one time and many other indigenous plants. Six types of vegetation witnessed, consequent to the re-vegetation programme launched by the Park Administration with assistance from FOOPS, are in three landform zones reflecting the soils derived from the underlying geology. These landforms are the plains and the escarpment. The overall picture of floral abundance that has emerged after the area was declared a national park is identification of 124 indigenous plant species including more than 20 species which are in the category of rare or threatened or significant.

Ked Ra Ngchemiangel, also known as the Kamyangel Terraces, are a series of sculpted landforms in Aimeliik, a state on the island of Babeldaob, the largest in the island nation of Palau. Located near the Kamyangel River near its entry into Ngchemiangel Bay, the terraced hills are clearly manmade forms created in unknown antiquity, and are arrayed in a curve overlooking the bay. When viewed from head-on, many of these terraces have a stepped "crown and brim" appearance similar to that of a brimmed hat. One of the hills is terraced to a height of .

The town borders Waubeka, the Town of Fredonia, and the Village of Fredonia to the north; the Town of Port Washington to the east; the Town of Grafton and the Cedarburg (town), Wisconsin to the south; and the Town of Trenton and the Village of Newburg to the west. The town is located in the Southeastern Wisconsin glacial till plains that were created by the Wisconsin glaciation during the most recent ice age. The town has many glacial landforms, including kames, kettles, and moraines. Much of the community is located on the Racine Dolomite formation that stretches through eastern Wisconsin and Illinois.

The town is also home to four Wisconsin State Natural Areas, including the 2,200-acre Cedarburg Bog, a National Natural Landmark that is the largest and best preserved bog in eastern Wisconsin, and has hiking trails and boardwalks. There are over a dozen publicly and privately owned bogs in the Saukville area that home to biodiverse ecosystems that occur in few other parts of the state. The private, nonprofit Riveredge Nature Center is located at another Wisconsin State Natural Area. The center's 61-acre property includes glacial landforms and diverse wildlife, and the center conducts educational programs throughout the year.

Lake Tight's origins date to nearly 2 million years before the modern era. As the Ice Age began to cool the Earth, and large glaciers began to creep south from modern-day Canada, many landforms and features were changed or destroyed, including the Teays River. The Teays had been a river for several million years, flowing north out of the Appalachian Mountains in what is now North Carolina. The river's path traveled through modern-day West Virginia, Kentucky, Ohio, Indiana, and Illinois, finally emptying into the Gulf of Mexico, which at the time extended to southern Illinois.

A broad saddle at elevation separates the Estancia basin from the Pinos Wells basin to the south. Initial research did not encounter shoreline landforms at the elevation of this sill and thus concluded that no overflow took place, but in the mid-20th century traces of a former shoreline were found above the sill elevation. Further late-20th century research did not find evidence of shorelines at overflow elevation or of flow at the supposed sill. The lake probably did not overflow during the Wisconsin glaciation; if there was overflow it took place over 130,000 years ago.

Sea stack on the east coast at Lingavi Geo In common with most of the Orkney isles, Shapinsay has a bedrock formed from Old Red Sandstone, which is approximately 400 million years old and was laid down in the Devonian period. These thick deposits accumulated as earlier Silurian rocks, uplifted by the formation of Pangaea, eroded and then deposited into river deltas. The freshwater Lake Orcadie existed on the edges of these eroding mountains, stretching from Shetland to the southern Moray Firth.McKirdy, Alan Gordon, John & Crofts, Roger (2007) Land of Mountain and Flood: The Geology and Landforms of Scotland.

The area is mostly covered by a Pliocene blanket of pyroclastic rocks and calc-alkaline lavas, Quaternary lahar deposits and fluvio-glacial deposits. The Buesaco-Aranda Fault has a very well-defined fault trace, with strongly deformed landforms of Pleistocene- Holocene age, clear breaks in slope along eroded fault scarps, and fault scarps facing both to the southeast or the northwest, which is a characteristic of strike-slip faults. Systematic right lateral deflections of some stream gullies, river channels, and ridges are visible. Offset features in confined alluvial deposits and in recent alluvial fans have fresh scarp morphology.

Further down in the Kobuk watershed, the river worked in concert with the wind to create one of the more famous landforms in Alaska: the Kobuk Dunes. These large sand dunes are the modern ancestor of alluvial deposits that became shaped and dominated by an exchange of aeolian and fluvial processes.Ashley, Gail and Hamilton, Thomas, Fluvial Response to Late Quaternary Climatic Fluctuations, Central Kobuk Valley, Northwestern Alaska. Journal of Sedimentary Petrology, Vol 63 No. 5, September 1993 pgs 814-827 In moister climates, the river has more water, and thus more power, and cuts down through a sandy bed.

The tallest among such landforms are Ivanšćica and Medvednica north of Zagreb and in Hrvatsko Zagorje as well as Psunj and Papuk which are the tallest among the Slavonian mountains surrounding Požega. Psunj, Papuk and adjacent Krndija consist mostly of Paleozoic rocks which are 350 - 300 million years old. Požeška gora, adjacent to Psunj, consists of much more recent Neogene rocks, but there are also Upper Cretaceous sediments and igneous rocks forming the main, ridge of the hill and representing the largest igneous landform in Croatia. A smaller igneous landform is also present on Papuk, near Voćin.

This means that in areas like north-east Sweden and northern Finland pre-existing landforms and deposits escaped glacier erosion and are particularly well preserved at present. Northwest to southeast movement of the ice has left a field of aligned drumlins in central Lapland. Ribbed moraines found in the same area reflects a later west to east change in movement of the ice. During the last deglaciation ice in Lapland retreated from the north-east, east and southeast so that the lower course of the Tornio was the last part of Finland to be deglaciated 10,100 years ago.

The beech forests of Rrajcë are part of the UNESCO Ancient and Primeval Beech Forests of the Carpathians and Albania. The national park features contrasting and diverse ecosystems, determined mainly by topography, climate, hydrology and geology. Those factors vary as altitude increases and so create a variety of environments, where different plants grow together in communities, which in turn provide favorable habitats for a wide range of wildlife. The montane ecosystem of the park offers a great diversity of landforms, together with an admirable plant and animal life, featuring meandering rivers, glacial lakes and vast meadows are surrounded by high mountains.

Supporters of the megaflood hypothesis note that the streamlined forms seen in the Athabasca Valles are inconsistent with a glacial hypothesis. They are unlikely to be drumlins, which are streamlined and teardrop-shaped in all three dimensions. In the Athabasca Valles, many relict features (including crater rims) still appear on the top of streamlined forms. Because Martian gravity is weaker, Martian glaciers would have to be much thicker than their terrestrial counterparts in order to overcome frictional basal forces and begin flowing (with estimated thicknesses up to 4–5 km); such theoretical glaciers would have covered such landforms.

Tokugawa-style entrance gates The Yuko-En on the Elkhorn garden features the traditional elements of a Japanese garden with plants and landforms native to Japan and Kentucky. The site's flat land was converted with 1400 truckloads of earth into gentle rising hills with gravel paths and arched bridges leading through a water garden, a Zen rock garden, and past the banks of Elkhorn Creek. The Tokugawa Gates at the entrance to the garden depict the Tokugawa Shogunate era in the form of Medieval European castle gates. A zigzag path leads into the garden through a patch of native cane.

This coast shows excellent examples of landforms, including the natural arch at Durdle Door, the cove and limestone folding at Lulworth Cove and a tied island, the Isle of Portland. Chesil Beach is a fine example of both a tombolo (a deposition landform in which an island is attached to the mainland by a narrow piece of land such as a spit or bar) and a storm beach (a beach affected by particularly fierce waves). The site has stretches of both concordant and discordant coastlines. Due to the quality of the varied geology, the site is the subject of international field studies.

The Tambo River at the Johnsonville junction Beginning in the Eastern Highlands, which is one of the three major landforms in Australia, the other two being the Central Lowlands and the Western Plateau, the Tambo River passes Johnsonville at approximately 5 km from its mouth. The Tambo River is just one of seven rivers that flow into the lakes, marshes and lagoons of the Gippsland Lakes system. The other rivers include Latrobe, Avon, Nicholson, Mitchell, Macalister and Thomson rivers. The river flows south and stretches 186 km which makes it only second in length to the Latrobe at 270 km.

The Sepik River is the longest river on the island of New Guinea, and after the Fly and the Mamberamo the third largest by volume.Fragmentation and Flow Regulation of the World’s Large River Systems The majority of the river flows through the Papua New Guinea (PNG) provinces of Sandaun (formerly West Sepik) and East Sepik, with a small section flowing through the Indonesian province of Papua. The Sepik has a large catchment area, and landforms that include swamplands, tropical rainforests and mountains. Biologically, the river system is often said to be possibly the largest uncontaminated freshwater wetland system in the Asia-Pacific region.

Level Mountain is part of the Northern Cordilleran Volcanic Province (NCVP), a broad area of volcanoes extending from northwestern British Columbia northwards through Yukon into easternmost Alaska. Volcanism in this geologic province can be traced as far back as 20 million years ago with the emplacement of alkali basalt in western Yukon. Several types of volcanic eruptions have since created different landforms across the NCVP, including shield volcanoes, lava domes, stratovolcanoes and cinder cones. Other volcanic formations, notably subglacial volcanoes, take their shape from the environment they formed, regardless of the type of magma they produced.

He also became interested in cartography and in 1921 he published Gli appunti storici sulla cartografia della Puglia. He also became interested in agricultural and economic geography by publishing an article on the distribution of crops in the province of Bari in 1922. In 1926 he completed his research, begun in 1916, on the karst morphology of Apulia's soil, during which he had analyzed Pulo di Altamura, Pulicchio di Gravina, Gurio Lamanna and other karst landforms. In the same year, he wrote the introduction on the karst phenomenon chapter for volume Duemila grotte published by Touring Club Italiano.

The tallest among such landforms are Ivanšćica and Medvednica north of Zagreb—both are also at least partially in Hrvatsko Zagorje—as well as Psunj and Papuk that are the tallest among the Slavonian mountains surrounding Požega. Psunj, Papuk and adjacent Krndija consist mostly of Paleozoic rocks from 300–350 Mya. Požeška gora, adjacent to Psunj, consists of much more recent Neogene rocks, but there are also Upper Cretaceous sediments and igneous rocks forming the main, ridge of the hill; these represent the largest igneous landform in Croatia. A smaller piece of igneous terrain is also present on Papuk, near Voćin.

Two of the most notable are the Avenida de Mayo and the Plaza de Mayo at Buenos Aires, near the location of the Cabildo. The Pirámide de Mayo was erected in the Plaza a year after the revolution, and was rebuilt to its present form in 1856. "May 25" (in Spanish, "Veinticinco de Mayo") is the name of several administrative divisions, cities, public spaces, and landforms of Argentina. There are departments of this name in the provinces of Chaco, Misiones, San Juan, Rio Negro, and Buenos Aires, the latter one holding the Veinticinco de Mayo city.

Strzeleckie Lake Chodzież is located in the northern part of Greater Poland (western Poland), in the Chodzieskie lakelands. The most important characteristics of this lakeland area are its typical postglacial landforms, forests of pines and mixed woodlands, and lakes. For this reason, the city's surroundings are known as "the Switzerland of Chodzież". Five kilometers west of Chodzież, at the edge of the Chodzieskie lakelands, Mt. Gontyniec (German: Tempel Berg) rises 192 meters above sea level as the highest peak in a chain of moraine hills; at the same time it has the highest elevation in northern Poland.

Marjorie Mary Sweeting (28 February 1920 - 31 December 1994 in Oxford), was a British geomorphologist specialising in karst phenomena. Sweeting had gained extensive knowledge on various typographies by travelling to places such as Greece, Australia, Czechoslovakia, United States, Canada, South Africa, Belize, and most notably China. She published Karst Landforms (Macmillan 1972), and Karst in China: its Geomorphology and Environment (Springer 1995) after many years of work there starting in 1977; the latter is the first comprehensive Western account of China's karst. She created one of the first western published works on the karst found within China, even in a male dominated field.

These landforms suggest that the mountain was formerly glaciated. Three sets of moraines have been described, one at elevation possibly linked to the last glacial maximum, an older one at elevation and a third at elevation which may have formed during the Little Ice Age; moraines reach thicknesses of . There is an additional set of moraines at elevation that has been correlated to pre-last glacial maximum glaciations, as well as traces of ice cored moraines and rock glaciers. Some rock glaciers still exist; unlike other glacial bodies in Chile the fronts of rock glaciers on Tacora are not retreating.

Recluse Nunatak () is an isolated rock exposure lying on the Handel Ice Piedmont, midway between Haydn Inlet and the Colbert Mountains in the west- central portion (facing towards the Wilkins Ice Shelf) of Alexander Island, Antarctica. The nunatak was first mapped from air photos taken by the Ronne Antarctic Research Expedition (RARE), 1947–48, by Searle of the Falkland Islands Dependencies Survey (FIDS) in 1960. The name given by the United Kingdom Antarctic Place-Names Committee (UK-APC) suggests the isolated position of the nunatak, considering this landform is situated far away from other landforms of Alexander Island.

The presence of older glacial deposits south of the Interstate Park demonstrates that the Laurentide Ice Sheet repeated glaciated it and surrounding areas over the Pleistocene Epoch. Within Wisconsin, these older glacial deposits consist of remnants of, highly weathered dark-gray loam till and lake sediment with reversed magnetic polarity and a deeply weathered, pre-Sangamonian Stage, reddish-brown, sandy loam till with normal magnetic polarity. Both the landforms and deposits related to these earlier glaciations have been either eroded or buried by the latest advance of the Laurentide Ice Sheet over this area of the Last Glacial Maximum.Johnson, M.D., 2000.

Lunar Crag () is one of the rock-exposed summits within the Planet Heights mountain range, rising to about at the head of Pluto Glacier on the east side of Alexander Island, Antarctica. It was photographed from the air by the Ronne Antarctic Research Expedition, 1947–48, and mapped from these photographs by D. Searle of the Falkland Islands Dependencies Survey in 1960. The crag was named by the UK Antarctic Place-Names Committee in 1977 in association with nearby landforms named after planets and satellites of the Solar System; other examples include Phobos Ridge and Jupiter Glacier.

As at 25 September 2008, Centennial Parklands is a unique place of exceptional National, State and Local heritage significance. It is a grand, linked open space of largely nineteenth-century landscape design intended for social and physical activity. The Parklands has developed at the head of the Botany Bay catchment in an area originally part of the territory of the Gadi people on lands designated in 1811 as the Sydney Common. The Parklands retains evidence of the original landforms and plays a vital role in sustaining natural processes and biological diversity on a scale that is rare in the inner urban environment.

Karst landforms and deep river valleys are widely distributed in the mountain. The park is composed by many smaller pieces, among which the Wenfeng Pagoda, the Golden Eagle Statue and the residences of George Catlett Marshall and Chiang Kai-shek during World War II are best known. The legendary home of Tushan Shi, the wife of Yu the Great, and his son Qi, who established Xia Dynasty, is also in the park. There are also many Buddhism and Taoism temples in this park, and many of them were constructed during Tang Dynasty (618 - 907) and Song Dynasty (960 - 1279).

From 1904–1905 Passarge held the post of Associate Professor of Geography in Berlin and in 1905 he became Professor of Geography in Breslau. In 1908 he joined the Colonial Institute in Hamburg, where he worked until 1936. He theorised that it should be possible for geographers to set up a taxonomic system for landforms, in much the same way as the biological sciences, although he favoured an empirical, descriptive system rather than a genetic one. Passarge's theories of racial geography (expounded in the 1920s in Das Judentum als landschaftskundlich-ethnologisches Problem) were embraced by the Nazi Party after 1933.

Cape Blanco, which is approximately north of Port Orford, is the westernmost point in Oregon. Cape Blanco extends further west than any point of land in the contiguous United States (lower 48 states) except Cape Alava, in Washington. Though the landforms of the region are relatively consistent, the South Coast shows a change in ecology. It is in this region that the western redcedar and Sitka spruce forests give way to the more southerly coast redwood, Port Orford cedar, and Douglas-fir forests, which also include the northern extent of Oregon Myrtle trees (aka California Bay Laurel).

Newspaper, 1991 With the reorganisation of armoured force personnel in 2005, and their departure from Army Training Group, Waiouru's population fell to about 2,000, but it was still often-used training area due to its central location and of varied landforms. The 1,400 beds in the barracks were frequently full, with more personnel using satellite camps or sleeping in the field. Waiouru continues to be the base for TAD (The Army Depot) and is the integral training base for the New Zealand Army. Most of the service people currently posted to Waiouru support training courses including the All Arms Recruit Course (basic training).

The Lord Howe Islands Group was inscribed on the World Heritage List for its unique landforms and biota, its diverse and largely intact ecosystems, natural beauty, and habitats for threatened species. It also has significant cultural heritage associations in the history of NSW. Lord Howe Island and adjacent islets, Admiralty Islands, Mutton Bird Islands, Ball's Pyramid, and associated coral reefs and marine environs were added to the Australian National Heritage List on 21 May 2007, on the basis of the World Heritage List. Lord Howe Island was listed on the New South Wales State Heritage Register on 2 April 1999.

MacManus, J. and R. W Duck, Internal seiches and subaqueous landforms in lacustrine cohesive sediments, Nature, 334, 511-513, 1988 caused by the action of the prevailing wind blowing along the loch. This wind pressure on the surface causes the water level to build up at one end of the loch. As with all damped mechanical systems, applied pressure can result in an oscillation, and the water will return to the opposite end of the loch over time. In the case of Loch Earn, this has a period of 16 hours and the effect can be measured, but is difficult to observe.

Valleys cross-cut the Phlegra ranges and are occasionally occupied to some degree by lineated valley fills. These landforms are intricately-patterned texturations that appears to demonstrate erosive characteristics in the upland, depositional characteristics in the lowlands, and indicators of directional flow between the two. In some valleys, lineated valley fills have been found to descend both the east and west foothills of the Phlegra mountain range system. These fills are sometimes banded by hummocky pits (interpreted as recessional moraines) and display regions where flow patterns appear turbulently disrupted or appear to have been backfilled by material associated with the flow.

At this time he started to study the late Quaternary deposits and landforms of southern Sweden. In 1897, he left his job in the geological service for the position of professor of general and historical geology at Stockholm University. In 1882, on the recommendation of Otto Martin Torell, de Geer participated in the Swedish expedition to Spitsbergen as part of the first International Polar Year as a staff geologist. This marks the beginning of many years of research on the modern glaciation of the Svalbard archipelago: in total he took part in six expeditions to Svalbard (1882, 1896, 1899, 1901, 1908 and 1910).

The system was prevalent during British Raj in many parts of India, including fertile plains of Punjab, in other places the jotedar system was prevalent. Since more of the tenants were poor labourer they had to borrow money from money lenders for cultivation, this perpetuated the poverty cycle. Though land reforms were implement across Bihar after independence through the Bataidari Act, but deemed exploitative against labourer and lead to violence, especially caste violence between labour communities and landowners. In the past, landforms have been demanded and even made a political plank in state assembly elections, especially by Left parties.

Continued south, they were baptizing the landforms that were not named on their maps. When they reach Punta Santa Ana, already in the Strait, on September 21, 1843, all the crew of the schooner went ashore and took formal possession of the surrounding territory on behalf of Chile and started the process to build Fuerte Bulnes. Before leaving to scout eastward on September 26 they left in Santa Ana a sign engraved with the words "Republic of Chile" and "Viva Chile!". After scouting the area, and having met a tribe of Tehuelches, they left the strait on 4 December to their way back.

A flared slope is a concave-upward or -inward bedrock surface that is typically found around the base of inselbergs, bornhardts, and granitic boulders and also on their higher slopes. Flared slopes like Wave Rock are particularly well developed in granitic landforms of south-western and southern Australia. The flared slopes are argued to have formed by the concentrated chemical weathering around the base of an inselberg by groundwater. The chemical weathering of the bedrock by groundwater produces a concave-upward or –inward pocket of deeply weathered, relatively loose, and disaggregated bedrock within the formerly solid bedrock base of an inselberg.

This is a list of birds of Victoria, Australia. Victoria is Australia's second-smallest state but has high biodiversity, with 516 bird species recorded — around 54% of Australia's total of 959 bird species in just 3% of Australia's land area. Birds are present in high concentrations in some areas, including the Western Treatment Plant at Werribee in Melbourne's suburbs, which is a haven for tens of thousands of birds, due to a combination of permanent water, varied landforms and plant species. Victoria contains a wider variety of natural habitats than any area of similar size in Australia.

William Morris Davis not only made important contributions to the establishment of discipline in his country but revolutionized the field to develop cycle of erosion theory which he proposed as a paradigm for geography in general, although in actually served as a paradigm for physical geography. His theory explained that mountains and other landforms are shaped by factors that are manifested cyclically. He explained that the cycle begins with the lifting of the relief by geological processes (faults, volcanism, tectonic upheaval, etc.). Factors such as rivers and runoff begin to create V-shaped valleys between the mountains (the stage called "youth").

The Little Harquahala Mountains are a small, arid, low-elevation mountain range of western-central Arizona, in the southeast of La Paz County. The range is northwest-by-southeast-trending and is in a region of about thirty landforms, plains, valleys, and mountain ranges called the Maria fold and thrust belt. The region is in the Basin and Range and three mountain ranges are in a parallel, northwest-by-southeast-trending thrust belt, with two intervening valleys. The Little Harquahala Range borders the second valley and third mountain range, the McMullen Valley and Harquahala Mountains, on their southwest borders.

It was the largest volcanic edifice between Mount Shasta in California and the Three Sisters complex in Oregon. Before the eruption, it had been significantly altered by glacial erosion, which carved U-shaped valleys on its southern and southeastern slopes. The northern and western sides of the caldera do not exhibit prominent evidence of glacial erosion, since they feature lava flows that only underwent alteration by late Pleistocene epoch glacial motion. Outside of the caldera, most hills show evidence of glacial alteration except those from the Holocene epoch and low elevation landforms including Pleistocene lava domes and cinder cones.

A parallel drainage system occurs on a common slope down linear ranges (or of rivers between linear series of escarpments, parallel, elongate landforms like outcropping resistant rock bands), typically following natural faults or erosion (such as prevailing wind scars). The watercourses run swift and straight, with very few tributaries, and all flow in the same direction. This system forms on very long, uniform slopes, for instance, high rivers flowing southeast from the Aberdare Mountains in Kenya and many rivers of Myanmar. This sometimes indicates a major fault that cuts across an area of steeply folded bedrock.

374, 378–379. Anna Coe died in 1941, but as she was ailing, Ernest Coe continued to write to politicians running for governor, as did Miami Herald editor John Pennekamp, urging them not to forget the directive of the park, particularly in the face of continuing poaching and destruction of the natural resources of the area. Originally, Coe envisioned of protected land, spanning from Lake Okeechobee to the Florida Keys, including marine coral reefs, and the Big Cypress Swamp. This was an extraordinary amount of land to consider, and the prevailing belief was that only spectacular landforms warranted protection.

In 1987, Susan S. Nedell and David W. Andersen (San Jose State University) and Steven W. Squyres (NASA Ames Research Center) reported on the presence of layered deposits across Valles Marineris, offering the first detailed observations about the structure, stratigraphy, distribution and composition of the landforms within the valley network on Viking imagery. They focused particularly on deposits in Candor Chasma, making some regional generalizations. Nedell and her co-authors offered preliminary hypotheses as to how these deposits formed. The researchers concluded that a lacustrine depositional mechanism was generally the most probable formational hypothesis, against aeolian or explosively volcanic hypotheses.

The THEMIS instrument, before being mounted onto Mars Odyssey. The Thermal Emission Imaging System (THEMIS) is a camera on board the 2001 Mars Odyssey orbiter. It images Mars in the visible and infrared parts of the electromagnetic spectrum in order to determine the thermal properties of the surface and to refine the distribution of minerals on the surface of Mars as determined by the Thermal Emission Spectrometer (TES). Additionally, it helps scientists to understand how the mineralogy of Mars relates to its landforms, and it can be used to search for thermal hotspots in the Martian subsurface.

The Hochstein (345 m) belongs to the many bunter sandstone rock formations that are typical of the Wasgau, a region that covers the southern part of the Palatine Forest and the northern part of the Vosges. Because the region of Dahn is especially rich in such landforms, it is known as the Dahn Rock Country (Dahner Felsenland). The Hochstein - like the other rock outcrops of the region - is made of a harder rock that has partly withstood erosion over the centuries. The entire massif runs for 1½ km east of Dahn across the Wieslauter stream and is heavily subdivided.

A patch of land that develops pools of water after a rain storm would not necessarily be considered a "wetland", even though the land is wet. Wetlands have unique characteristics: they are generally distinguished from other water bodies or landforms based on their water level and on the types of plants that live within them. Specifically, wetlands are characterized as having a water table that stands at or near the land surface for a long enough period each year to support aquatic plants. A more concise definition is a community composed of hydric soil and hydrophytes.

The Sydney Harbour National Park is an Australian national park comprising parts of Port Jackson, Sydney and its foreshores and various islands. The national park lies in New South Wales and was created progressively, from 1975. The national park protects the landforms of Bradleys Head, Clark Island, Dobroyd Head, Fort Denison, Georges Head, Goat Island, Middle Head, Nielsen Park, Rodd Island, Shark Island, Sydney Heads including the Quarantine Station at North Head and The Gap bluff at South Head. The national park also protects the waterway between North Head and Dobroyd Head, defined as the North Sydney Harbour Aquatic Reserve.

Dogs and sheep were among the first animals to be domesticated, and they remain in wide use today. Charles Darwin, Jared Diamond and others have noted the importance of domesticated mammals in the neolithic development of agriculture and of civilisation, causing farmers to replace hunter-gatherers around the world. This transition from hunting and gathering to herding flocks and growing crops was a major step in human history. The new agricultural economies, based on domesticated mammals, caused "radical restructuring of human societies, worldwide alterations in biodiversity, and significant changes in the Earth's landforms and its atmosphere... momentous outcomes".

When it reached Cerro Rosado, the avalanche climbed about and mostly continued to flow southeast into the main avalanche path, with only a small flow continuing northeastwards. Part of the run-up avalanche later collapsed backwards over the main avalanche deposit. Unlike Socompa farther north, a landslide scar is only poorly developed at Llullaillaco despite the large size of the collapse; it was largely filled in later by lava flows and volcaniclastic debris. This landslide has been subdivided into four facies and features landforms like levees up to high, longitudinal ridges and a run-up mark on Cerro Rosado.

The world heritage area is known as the Gondwana Rainforests of Australia that protects several remnants of subtropical rainforest with high biodiversity and unique geological landforms, with evolutionary links to Gondwana. In 2009 BirdLife International identified the Nightcap Range as important bird and biodiversity areas (IBA). The Nightcap Range IBA includes Nightcap NP, Mount Jerusalem NP, Goonengerry NP and Whian Whian State Conservation Area (SCA). It has been recognised for its populations of Albert's lyrebird (Menura alberti), green catbird (Ailuroedus crassirostris), pale-yellow robin (Tregellasia capito), Australian logrunner (Orthonyx temminckii), paradise riflebird (Ptiloris paradiseus) and regent bowerbird (Sericulus chrysocephalus).

There are six main landforms in Kakadu National Park: the Arnhem Land plateau and escarpment complex, known as the stone country; the outliers; the lowlands; the southern hills and basins; the floodplains; and the tidal flats. Each landform has its own range of habitats. Kakadu's varied landscapes and the habitats they contain are features that contributed to its listing as a World Heritage Area. The Mamukala wetlands Most of Kakadu was under a shallow sea approximately 140 million years ago, with the escarpment wall formed from sea cliffs and Arnhem Land from a flat plateau above the sea.

The tallest peaks are in the High Atlas range in south-central Morocco, which has many snow-capped peaks. South of the Atlas Mountains is the dry and barren expanse of the Sahara desert, which is the largest sand desert in the world. In places the desert is cut by irregular watercourses called wadis—streams that flow only after rainfalls but are usually dry. The Sahara's major landforms include ergs, large seas of sand that sometimes form into huge dunes; the hammada, a level rocky plateau without soil or sand; and the reg, a level plain of gravel or small stones.

Danmark in Norway. It is a typical Nordic skerry. As suggested by its origin as islette, an Old French diminutive of "isle",Webster's New International Dictionary of the English Language, Second Edition, 1958 use of the term implies small size, but little attention is given to drawing an upper limit on its applicability. The World Landforms website says "An islet landform is generally considered to be a rock or small island that has little vegetation and cannot sustain human habitation", and further that size may vary from a few square feet to several square miles, with no specific rule pertaining to size.

One of the most important roles of the engineering geologist is the interpretation of landforms and earth processes to identify potential geologic and related manmade hazards that may impact civil structures and human development. Nearly all engineering geologists are initially trained and educated in geology, primarily during their undergraduate education. This background in geology provides the engineering geologist with an understanding of how the earth works, which is crucial in mitigating earth related hazards. Most engineering geologists also have graduate degrees where they have gained specialized education and training in soil mechanics, rock mechanics, geotechnics, groundwater, hydrology, and civil design.

Where the glaciers made their way into the valley, one can still find glacial landforms such as cirques, caroids (Karoide) and cirque lakes (Großer Arbersee, Kleiner Arbersee, Rachelsee) as well as moraine banks. The Rachelsee The toe of the glacier, for example near the Grosser Arbersee, was located at a height of 850 metres, the snout of the northern glacier down to the small Arbersee at a height of about 830 metres. Accordingly, there was a considerable difference in height of more than 600 metres from the summit regions to the terminal moraines. Other glacial tongues flowed down from the Grosser Rachel.

Northeast of the Bonaparte Plateau there is a semi- mountainous region near the southern boundary of Wells Gray Provincial Park that is part of the Shuswap Highland (or the Quesnel Highland, depending on which definitions are used). The plateau is a mix of wilderness, large ranch holdings, and private recreational properties. The group of hills immediately northeast of Cache Creek have been preserved as the Arrowstone Hills Provincial Park. The Arrowstone Hills, the highest summit of which is 1,791 metres (5,876 ft), feature sand canyons, hoodoos and other unusual landforms and a rich wildlife population, including rattlesnake.

A study published in Icarus, found that the landforms of scalloped topography can be made by the subsurface loss of water ice by sublimation under current Martian climate conditions over periods of tens of thousands of Mars years. Scalloped depressions are thought to begin with a small trigger like a small impact, local darkening, erosion, or cracks from thermal contraction. Cracks are common in ice-rich ground on the Earth. Their model predicts that these scalloped depression will develop when the ground has large amounts of pure ice, up to many tens of meters in depth.

Despite its urban character, the San Francisco Bay is one of California's most ecologically important habitats, providing key ecosystem services such as filtering pollutants and sediments from the rivers, and supporting a number of endangered species. In addition, the Bay is known for its strands of coast redwoods, many of which are protected in state and county parks. The region is also known for the complexity of its landforms, the result of millions of years of tectonic plate movements. Because the Bay Area is crossed by six major earthquake faults, the region is particularly exposed to hazards presented by large earthquakes.

This reflects a climate which would have been created by the proximity of the ice sheet. Younger sediments contain pollen and plant fossils of a hemlock-hardwoods association, reflecting the moderating climate as the ice sheets retreated northward. White (1896) and Marine (1997) described five terraces that occur along or near the valley walls of the Ohio, Monongahela, and Allegheny Rivers and their major tributaries in Pennsylvania and West Virginia. These relatively flat landforms contain soils composed of highly weathered deposits of clay, silt, sand, and gravel distributed at elevations as high as above present stream levels.

Sections of these collapsed lava tubes now form volcanic pits. Extensive areas of nearly flat-lying lava flows throughout the Northern Cordilleran Volcanic Province can cover areas of at least and are generally composed of highly-fluid basaltic lava. However, lava plains that pre-date the last glacial period have been eroded and overridden by glacial ice, affording a less distinctive form to these older landforms. For example, lava beds at least a million years old in central Yukon contain unconsolidated glacial deposits that were deposited when glacial ice rode on top of the lava flows comprising the lava beds.

Although it is not a national park, the Ngorongoro Conservation Area (NCA) with an area of was recognized by the United Nations Educational, Scientific and Cultural Organization as a World Heritage Site in 1979. The criteria cited for this recognition include: (1) crucial evidence found within the NCA about human evolution and human-environment dynamics (this criterion added in 2010); (2) the "stunning landscape" of Ngorongoro Crater, the largest unbroken caldera in the world; (3) the NCA's large concentration of wildlife, including 25,000 large animals; and (4) the NCA's variations in climate, landforms and altitude, resulting in several overlapping ecosystems and distinct habitats.

Alishan is the main base for trekkers in the highlands of Taiwan and for mountain climbers aiming to scale Yu Shan, Taiwan's highest peak and the highest and sole formerly glaciatedLate Pleistocene to early Holocene glacial landforms of Yushan point on the Tropic of Cancer. Chu Shan, though lower, is more accessible and climbed by most visitors to the region, which is extremely popular with Taiwanese tourists. The highland region in which Alishan is situated also contains a number of notable rock formations from the continuing uplift of the island. Jiao Lung Waterfall, Taiwan's tallest waterfall, is located within the township.

The Tibesti mountains feature a desert mountain climate. There are no weather stations close to Emi Koussi and the stations at lower elevations likely underestimate precipitation at higher elevations, but based on cloud cover data, a yearly precipitation of has been estimated for Emi Koussi; in the past it was wetter than this. The climate reflects both northerly and southerly influences and is distinct from that of the surrounding deserts. There is no evidence of nivation forms on Emi Koussi and the identification of periglacial landforms is questionable, although periglacial activity likely occurred in the Pleistocene and may continue to the present-day.

Many of the most impressive landforms are composed of more resistant rocks, including the Jurassic Navajo Sandstone, Jurassic Wingate Sandstone, and Permian Coconino Sandstone. The folding is much steeper on the eastern edge of the Swell than in the west, and this eastern edge is referred to as the San Rafael Reef. Both the San Rafael River and Muddy Creek drain out of the high Wasatch Plateau and the cut directly across the uplift of the Reef, which marks them as superimposed streams, pre-dating the time of the uplift. Part of the Swell has geographic features that resemble Mars.

Major landforms of East Tennessee The Ridge-and-Valley section, often called the Tennessee Valley or "Great Valley", is the region's largest and most populous section. It consists of a series of alternating elongate ridges and broad river valleys roughly oriented northeast-to-southwest. This section's most notable feature, the Tennessee River, forms at the confluence of the Holston and French Broad rivers in Knoxville, and flows southwestward to Chattanooga, where it enters the Tennessee River Gorge. Other notable rivers in the upper Tennessee watershed include the Clinch, Nolichucky, Watauga, Emory, Little Tennessee, Hiwassee, Sequatchie, and Ocoee rivers.

Mega tsunami of the world oceans: Chevron dune formation, micro-ejecta, and rapid climate change as the evidence of recent oceanic bolide impacts: T. Beer (ed.), Geophysical Hazards, p. 197-227; Springer Publ. Part of the evidence they cite for this hypothesis is that the sediments contain tiny marine fossils; however, such fossils can be moved by the wind, just like sand. The impact idea is controversial not only because chevrons are similar to wind-blown landforms found far from the ocean, but also because it is unlikely that there have been enough large impacts and landslides to explain the observed chevrons.

The hole, Tuxis Pond, was filled in the resulting splash. Odziozo then turned, stepping on the rock (It is assumed his legs were grown in by then), and went back to Vermont to get to his home, Rock Dunder, where, exhausted, he turned himself into a stone, so as to be permanently with his favorite creation. Odziozo is often said to have lived before animals evolved legs, and, as such, many of the landforms he created were caused by the dragging of his body by his long arms. Rock Dunder, in Shelburne, Vermont, is supposedly where his spirit and body are kept.

Karst topography predominates in that area, resulting in specific landforms and hydrology because of the interaction of the karst and the region's watercourses—this is exemplified by the Plitvice Lakes. Most of the region has a moderately warm and rainy continental climate, although there is considerable seasonal snow at greater elevations. The region belongs almost exclusively to the Black Sea drainage basin and includes most of the large rivers flowing in Croatia. The boundaries of Croatia proper were shaped by territorial losses of medieval Croatia to the Republic of Venice and the Ottoman conquest starting in the 15th century.

'Extensums' are usually outdoor works, which 'extend' a space in Rhodes' terms; 'intensums' are usually installations inside buildings, where space is intensifed. Rhodes began training as a cross-country runner in 1978 and went on to compete regularly in marathon and cross-country events. In 1998 art historian Priscilla Pitts wrote: > Every day she runs long distances on the hills, often along Summit Road, > 'absorbing the landforms' not just with her eyes, but also through the soles > of her feet. She becomes kinetically intimate with the landscape, her whole > body responding to the varying nature of the terrain.

A homoclinal ridge or strike ridge is a hill or ridge with a moderate, generally between 10° to 30°, sloping backslope. Its backslope is a dip slope, that conforms with the dip of a resistant stratum or strata, called caprock. On the other side of the other slope, which is its frontslope, of a homoclinal ridge is a steeper or even cliff-like frontslope (escarpment) that is formed by the outcrop of the caprock. The escarpment cuts through the dipping strata that comprises the homoclinal ridge.Cotton, C.A. (1952) Geomorphology An Introduction to the Study of Landforms.

The geology of the area in which the Green Bridge of Wales is located is composed of a very thick layer of Carboniferous Limestone, including a certain amount of chert. Erosion has occurred over time as storm winds have battered the coast, pebbles have been dashed against the rocks, sand particles have worn away the surface, and chemical erosion has dissolved the limestone. The weakest parts of the cliff are the first to be worn away, usually the folds and small faults that are present in the rocks. This has resulted over many millennia in the creation of many unusual landforms.

Central Park is divided into three sections: the "North End" extending above the Jacqueline Kennedy Onassis Reservoir; "Mid- Park", between the reservoir to the north and the Lake and Conservatory Water to the south; and "South End" below the Lake and Conservatory Water. The park has five visitor centers: Charles A. Dana Discovery Center, Belvedere Castle, Chess & Checkers House, the Dairy, and Columbus Circle. The park has natural- looking plantings and landforms, having been almost entirely landscaped when built in the 1850s and 1860s. It has eight lakes and ponds that were created artificially by damming natural seeps and flows.

While earlier archaeological remains suggest more ancient settlement in the area (including a ringfort in nearby Larragan townland), the modern day Clonaslee evolved from its beginnings as an Anglo-Norman town of the late-12th century. At this time the eskers and related landforms gave a great strategic advantage by providing ideal vantage points where mottes and other defensive battlements were constructed. This advantage also had a profound influence on the location of towns and villages throughout the county. From the 12th to 17th centuries, recorded history does not provide much detail on the development of Clonaslee.

This scenic drive is unique in the system since it is designed through tight canyon lands beside a gushing mountain stream. The drive expresses the idea of expanding the park and parkway system into the mountains and through rough terrain and unusual landforms outside the city limits yet accessible to city residents and tourists. One of the purposes of the drive was to protect the area from the encroachment of growth and has significance in community development and planning. Growth could damage the scenic character, allow structures in the floodplain, and remove this special area from public use.

As a result, stones just a few centimeters high feel the full force of ambient winds and their gusts, which can reach in winter storms. Such gusts are thought to be the initiating force, while momentum and sustained winds keep the stones moving, possibly as fast as a moderate run. Wind and ice both are the favored hypothesis for these sliding rocks. Noted in "Surface Processes and Landforms", Don J. Easterbrook mentions that because of the lack of parallel paths between some rock paths, this could be caused by degenerating ice floes resulting in alternate routes.

Maligne Lake in Jasper National Park Spirit Island on Maligne Lake Maligne Lake is the largest lake in Jasper National Park. The valley in which the lake lies was carved and excavated by valley glaciers, and the lake has been dammed at its northern end by an end moraine deposited by the last glacier, which flowed down the valley towards the Athabasca River. The glacial deposits and landforms forming the end moraine are excellent examples of glacial deposition.www.ags.gov.ab.ca The highest peak in the area is Mount Brazeau (), which stands southeast of Maligne Lake at the head of the Brazeau Icefield.

The geology of Georgia is the study of rocks, minerals, water, landforms and geologic history in Georgia. The country is dominated by the Caucasus Mountains at the junction of the Eurasian Plate and the Afro-Arabian Plate, and rock units from the Mesozoic and Cenozoic are particularly prevalent. For much of its geologic history, until the uplift of the Caucasus, Georgia was submerged by marine transgression events. Geologic research for 150 years by Georgian and Russian geologists has shed significant light on the region and since the 1970s has been augmented with the understanding of plate tectonics.

The Guilsborough Park landscape related to the former Guilsborough Hall. Various significant trees and tree groups remain (with TPO's) and other important landscape features include the brick water tower of the hall and the hall gates. In the fields east of Guilsborough and both north and south of the West Haddon Road (just east of the 'PCS' access road) lie recorded prehistoric and Iron Age remains. A Saxon settlement also seems likely to have been located along the brook by the gated road (east west across Cold Ashby Road and obvious landforms can be seen immediately west of the old mill and stables.).
