Question

Quizplus · Accepted Answer

A U-shaped cross-valley profile is typical of canyons and valleys eroded and deepened by alpine or valley glaciers. The steep sides of the valley are eroded by the moving glacier, resulting in a wide, flat bottom with a gentle slope. The shape of the valley resembles the letter "u" hence it is called a U-shaped valley.
