Question

Glaciers do not form deep narrow valleys. Why?

Answer 1

1. The Glaciers form U-shaped valleys with steep, straight sides and a flat or rounded bottom.
2. It is in contrast to the valleys carved by rivers to be V-shaped in cross-section.
3. Glaciated valleys are formed when a glacier travels across and down a slope, carving the valley by the action of scouring.
4. So glaciers do not form deep narrow valleys.
