Question

Explain the formation of a waterfall

Answer 1

A waterfall is a river or other body of water's steep fall over a rocky ledge into a plunge pool below. ... Often, waterfalls form as streams flow from soft rock to hard rock. This happens both laterally (as a stream flows across the earth) and vertically (as the stream drops in a waterfall).

Answer 2

Step-by-step explanation:

Waterfalls often form in the upper stages of a river where it flows over different bands of rock. It erodes soft rock more quickly than hard rock and this may lead to the creation of a waterfall. The soft rock erodes more quickly, undercutting the hard rock.
