Glacier processes and landforms

Although on pictures glaciers seem almost motionless, their mass movement is one of the most powerful forces shaping the Earth's surface. Under the weight of accumulating ice and snow, the glacial ice is deformed and begins to move downslope by pseudo-plastic flow, slipping over the surface lubricated by meltwater at their base.
Glacial ice movement together with the transported material destroy the bedrock, erode slopes of valleys, reshape existing landforms, move and accumulate material on sides, at the bottom, and in the forehead of glaciers.
During this lecture, students will learn about glacial landforms and processes, including erosion, transportation, deposition, and weathering.
