Question

how the v shaped vallies were formed ?​

Answer 1

Answer:

Rivers begin high up in the mountains so they flow quickly downhill eroding the landscape vertically. As the river erodes downwards the sides of the valley are exposed to freeze-thaw weathering which loosens the rocks (some of which will fall into the river) and steepens the valley sides.
