The shape of a valley carved by a glacier is U shaped. A valley carved by a river is V shaped.
Glacier valleys have a u shape
A moving mountain glacier can carve a U-shaped valley. As the glacier moves downhill, it erodes the sides and bottom of the valley, creating a distinctive U-shaped cross-section. The glacier's immense weight and motion combined with erosion from the ice can shape the landform over time.
As a glacier moves through a valley, it digs deep into the walls and floor . A once-narrow valley that had a V shape becomes wider. As a glacier moves through, the valley becomes U shape .
