Examples of Depositional Landforms; Landform Description Image Dunes: A dune is a large pile of wind-blown material, typically sand or snow. As the pile accumulates, its larger surface area increases the rate of deposition in a positive feedback loop until the dune collapses under its own weight. This process causes dunes to move in the ...
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 ...
Sketch showing the main glacio-lacustrine (or glacio-marine) deposits & depositional processes. Sediments deposited into lakes that have come from glaciers are called glaciolacustrine deposits. In some European geological traditions, the term limnoglacial is used. These lakes include ice margin lakes or other types formed from glacial erosion ...
The Irish word was and is used particularly to describe long sinuous ridges, which are now known to be deposits of fluvio-glacial material. The best-known example of such an eiscir is the Eiscir Riada , which runs nearly the whole width of Ireland from Dublin to Galway , a distance of 200 km (120 mi), and is still closely followed by the main ...

Satellite image of kettle lakes in Yamal Peninsula (Northern Siberia), adjacent to the Gulf of Ob (right). The lake colors indicate amounts of sediment or depth. A kettle (also known as a kettle hole, kettlehole, or pothole) is a depression or hole in an outwash plain formed by retreating glaciers or draining floodwaters.
The word kame is a variant of comb (kame, or kaim is the Old Scottish word meaning 'comb'), which has the meaning "crest" among others. [2] The geological term was introduced by Thomas Jamieson in 1874. [3] According to White, "kames were formed by meltwater which deposited more or less washed material at irregular places in and along melting ice.
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.
