What are examples of landforms created by glacial erosion?
As a glacier moves, it picks up rock pieces from the landscape. Debris of all sizes that is stuck in the glacial ice can scour and erode the land. From this action, valleys can become wider and deeper, forming u-shaped (or trough) valleys. Glaciers can carve bowl-shaped depressions, called cirques, into a mountainside. A tarn is a lake that forms by ice melting in a cirque. An arête is the steep ridge that forms between two adjacent cirques. A col is a low spot on an arête. A horn is a peak formed when three or more adjacent cirque glaciers carve away the side of a mountain. Continental glaciers scour linear finger lakes out of pre-existing stream channels. Paternoster lakes are a series of lakes that form in the low spots of a u-shaped valley; a stream that flows through the valley links them. What are some landforms created by glacial deposition? A glacier will deposit rock chunks along the sides and the front of it. Moraines are created when a glacier pushes or carries along this ro
