A V-shaped valley eroded by a river is called a canyon.
Usually V-shaped.
A v-shaped valley eroded by a river is called a river valley. This type of valley is characterized by steep sides and a narrow bottom, formed by the erosive action of the river over time.
Possibly a V-shaped valley or a U-shaped valley. The U- Shaped valley would have been eroded by a glacier meaning it has a wider and flatter base. But the V-shaped valley would have interlocking spurs, and caves which would turn into corries. So, overall, I would say that the river valley that looks like a crescent would have to be the V-shaped valley.
A stream shaped valley is usually 'V' shaped. A glacier formed valley is usually 'U' shaped.
You can transform a v-shaped valley into a u-shaped valley by a glacier.
You can transform a v-shaped valley into a u-shaped valley by a glacier.
A V-shaped valley has been formed by a river. A U-shaped valley has been formed by a glacier.
V-shaped Valley
no
v shaped valley
The shape of a valley carved by a glacier is U shaped. A valley carved by a river is V shaped.
A U-shaped valley is a geological formation formed by the erosive action of a glacier. Ice moving downhill carves out a broad, U-shaped valley with steep sides and a flat bottom. These valleys are characteristic of areas that have been shaped by glacier activity.
v shaped valleys is one of them
