Respuesta :
U; V
Valleys carved by glaciers tend to be shaped like the letter U due to the erosive power of the ice. As glaciers move through the landscape, they scoop out large chunks of earth and rock, creating a rounded U-shaped valley. The sides of the valley tend to be steep, and the valley floor is often flat or gently sloping. This shape is because the ice erodes the rock and soil on the sides and bottom of the valley but cannot erode the top of the valley as efficiently.
Valleys carved by water tend to be shaped like the letter V. The erosive power of water is much less than that of glaciers, but it still can slowly wear away the rock and soil. Over time, this creates a V-shaped valley with steep sides and a flat or gently sloping floor. This shape is because the water erodes the sides and bottom of the valley but cannot erode the top of the valley as efficiently. The result is a V-shaped valley with a narrow opening at the top.
