Glacial erosion is the process of glaciers wearing away the landscape. Glaciers erode rocks and sediment that they come into contact with. This process can create deep valleys, U-shaped valleys, and glacial landforms.
Glacial Erosion
Glacial Erosion: The process of erosion caused by the movement of glaciers as they move over the land. Plucking: When pieces of rock are removed from exposed bedrock by the movement of a glacier. Abrasion: The process of wearing down or grinding down rock surfaces by the movement of rocks embedded in the bottom and sides of a glacier.
Concepts:
Glaciers can erode bedrock up to 100 meters below sea level. Glacial erosion can form unique landforms, such as hanging valleys, U-shaped valleys, cirques, and horns. Glacial erosion creates deep fjords in coastal areas, which can be up to 1000 meters deep.
