Map of Cape Cod showing shores undergoing erosion (cliffed sections) in yellow, and shores characterized by marine deposition (barriers) in blue. [1] Deposition is the geological process in which sediments, soil and rocks are added to a landform or landmass.
Aeolian landforms, or Eolian landforms, are produced by either the erosive or depositive action of wind. These features may be built up from sand or snow , [ 1 ] or eroded into rock, snow, or ice. Aeolian landforms are commonly observed in sandy deserts and on frozen lakes or sea ice and have been observed and studied around Earth and on other ...
Aeolian landform – Landforms produced by action of the winds include: . Dry lake – Area that contained a standing surface water body; Sandhill – Type of ecological community or xeric wildfire-maintained ecosystem
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 ...
Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills , mountains , canyons , and valleys , as well as shoreline features such as bays , peninsulas , and seas , [ 3 ] including submerged features such as mid-ocean ridges , volcanoes , and the great ocean basins .
A diagram of various depositional environments. In geology, depositional environment or sedimentary environment describes the combination of physical, chemical, and biological processes associated with the deposition of a particular type of sediment and, therefore, the rock types that will be formed after lithification, if the sediment is preserved in the rock record.
Fluvioglacial landforms or glaciofluvial landforms [a] are those that result from the associated erosion and deposition of sediments caused by glacial meltwater. Glaciers contain suspended sediment loads, much of which is initially picked up from the underlying landmass.
Geomorphically relevant processes generally fall into (1) the production of regolith by weathering and erosion, (2) the transport of that material, and (3) its eventual deposition. Primary surface processes responsible for most topographic features include wind , waves , chemical dissolution , mass wasting , groundwater movement, surface water ...
