By what two processes do glaciers erode
WebMay 20, 2024 · As the glacier slides over Earth’s surface, it erodes its surface by polishing bedrock, pushing soil, grinding up rock, and digging into the ground. Through this process, called glaciation, glaciers carve out unique landscapes like the U-shaped valley of Lake McDonald Valley in Glacier National Park, Montana, United States. WebErosional landforms As the glaciers expand, due to their accumulating weight of snow and ice they crush and abrade and scour surfaces such as rocks and bedrock. The resulting erosional landforms include striations, cirques, glacial horns, arêtes, trim lines, U-shaped valleys, roches moutonnées, overdeepenings and hanging valleys .

WebThe two main types of erosion are: Abrasion - as the glacier moves downhill, rocks that have been frozen into the base and sides of the glacier scrape the... Plucking - rocks … WebAug 19, 2024 · The two important processes of glacial erosion are plucking and abrasion. Plucking: It is the erosion and transportation of pieces of rocks. In this process, glaciers expand over large areas of Earth’s surface; while going through this process, some ice melts, and water percolates into the cracks present in the rocks below the glacier.
