Question

Why does erosion take place in the upper course of a river?

Answer 1

VERTICAL EROSION is the main process in the upper course of the river, as the river wants to get to sea level. This process creates five distinctive features; a v- shaped valley, interlocking spurs, waterfalls, gorges and rapids. These occur when there are horizontal bands of hard and soft rock.
