Question

Quizplus · Accepted Answer

Sharp ridges and U-shaped valleys are characteristic features of mountains that have undergone glaciation, which is the process of carving and shaping mountains by the movement of glaciers. Stream erosion can create V-shaped valleys, but not U-shaped valleys. Wind erosion can create features like sand dunes and rock formations, but not sharp ridges or valleys. Diastrophism refers to movements of the earth's crust, but it doesn't create specific landforms like the ones described in the question.
