A V-shaped valley eroded by a river is called a canyon.
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 'V' shaped valley has been formed by a stream or river. A 'U' shaped valley has been formed by the action of a glacier. Therefore, should a glacier form in the mountains, the ice, pushed downhill by the weight of fresh snow constantly being added high above, will gouge out the 'V' shaped river valley and form the 'U' shaped glacial valley.
