How does a glacier move like a stream
WebGlaciers erode the bedrock in two major ways: (1) abrasion and (2) plucking. Abrasion is a grinding, sandpaper-like process, where rock particles of many sizes are entrained in the glacial ice and scraped against the bedrock as the … WebAs a glacier flows, weathering takes place on the land around it. The main weathering process is known as freeze-thaw weathering. This is where water, either rain water or meltwater from the...

WebMay 20, 2024 · As a glacier moves, it scratches Earth’s surface, picking up everything from small rocks to boulders the size of a house. These rocks and boulders become stuck in … WebGlaciation. Glaciation: is the modification of the land surface by the action of glaciers. Glaciations have occurred so recently in N. America and Europe, that weathering, mass wasting, and stream erosion have not had time to alter the landscape. Thus, evidence of glacial erosion and deposition are still present.
WebIce Flow: Glaciers move by internal deformation (changing due to pressure or stress) and sliding at the base. Also, the ice in the middle of a glacier actually flows faster than the ice along the sides of a glacier as shown by the rocks in this illustration (right). WebGlaciers in temperate zones tend to move the most quickly because the ice along the base of the glacier can melt and lubricate the surface. Other factors that affect the velocity of a glacier include the roughness of the rock surface (friction), the amount of meltwater, and the weight of the glacier. Basal sliding and plastic flow.
