what landform makes a u shaped valley
U shaped Valley-Yosemite. As a glacier moves downhill through a valley, the shape of the valley is transformed. A V-shaped valley is transformed into a U-shaped valley through the glacial erosion processes of plucking and abrasion. This results in large rocky material (glacial till) being carried in the glacier.A material called boulder clay is deposited on the floor of the valley.-shaped valley in Leh valley, Ladakh, NW Indian Himalaya. The glacier visible at the head of the valley is the last remnants of the formerly much more extensive valley glacier which carved this valley.
