WebSep 3, 2024 · The movement of ice in the form of glaciers has transformed our mountainous land surfaces with its tremendous power of erosion. U-shaped valleys, hanging valleys, cirques, horns, and aretes are features sculpted by ice. The eroded material is later deposited as large glacial erratics, in moraines, stratified drift, outwash plains, and drumlins.
