A glacier molds itself to the land and also molds the land as it creeps down the valley. Many glaciers slide on their beds, which enables them to move faster.

How Do Glaciers Change the Landscape? Sciencing

WebAs glaciers erode by plucking, abrasion, and freeze-thaw weathering, they can create landforms such as corries, arêtes, pyramidal peaks, u-shaped valleys, and truncated … WebGlaciers move by internal deformation of the ice, and by sliding over the rocks and sediments at the base. Internal deformation occurs when the weight and mass of a glacier causes it to spread out due to gravity. Sliding occurs when the glacier slides on a thin layer of water at the bottom of the glacier.
