· abrasion - The sediment that ends up getting frozen into glaciers causes A glacier that flows down slope is a powerful erosive agent. The movement of glaciers predominantly erodes by abrasion/scouring and plucking. In the abrasion Our results depict the Alpine glacier erosion landscape as a time-transgressive patchwork, with different parts of the range corresponding to different glaciation 22 Jan 2021 How to cite.

Glacial landform geologi

Glacier is an enormous sheet of snow-covered ice that slowly accumulates on a mountain. When the ice below it starts to melt, the glacier may start to move, consequently, eroding the mountain. Glaciers form in areas that are frequently covered by snow. Most erosion is performed by liquid water, wind, or ice (usually in the form of a glacier). If the wind is dust y, or water or glacial ice is muddy, erosion is taking place.
