Here's a breakdown:
* Glaciers are massive bodies of ice that flow slowly over time.
* Erosion occurs as the glacier's weight and movement grinds against the bedrock, carving out the landscape.
* Glacial valleys are characteristically U-shaped, with steep sides and a flat bottom, in contrast to the V-shaped valleys formed by rivers.
Other features sculpted by glacial erosion include:
* Cirques: Bowl-shaped depressions at the head of a glacier.
* Aretes: Sharp ridges separating two cirques.
* Horns: Pointed peaks formed by the intersection of three or more cirques.
* Fjords: Deep, narrow inlets of the sea carved by glaciers.
