Introduction. Subglacial erosion rates range over many orders of magnitude, from among the slowest to among the fastest observed in common geomorphic environments (Koppes and Montgomery, Reference Koppes and Montgomery 2009). Glacialerosion är all nötning, slipning, lossbrytning och upplockning av berg- och jordmaterial som sker genom inverkan av en glaciär eller inlandsis. En viktig form av den glaciala erosionen är glacial abrasion, som uppstår i samband med att en glaciär glider över sitt underlag. Past and future impact of glacial erosion in Forsmark and Uppland. Final report. SKB TR-19-07.

The first that we will talk about is plucking, which Various Features of Glacial Erosion Cirque. A cirque, also known as a corrie, is a valley created because of glacial erosion. The shape of the valley is Cirque Stairway. If a series of cirques are arranged one above the other at different elevations, it is called a cirque U-Shaped Valleys.

Glacial erosion

The highest of these sides is called the headwall. Courtesy of Rocky Mountain National Park. Glaciers can shape landscapes through erosion, or the removal of rock and sediment. They can erode bedrock by two different processes: Abrasion: The ice at the bottom of a glacier is not clean but usually has bits of rock, sediment, and debris. It is rough, like sandpaper. Glacial erosion is when soil or rocks are worn down or moved by a glacier, creating many impressive and unique landscape features.
