Question

how does a waterfall develop? explain it using an appropriate diagram​

Answer 1

Answer:

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

Explanation:

Formation of a waterfall:

1. The soft rock erodes more quickly, undercutting the hard rock.
2. The hard rock is left overhanging and because it isn’t supported, it eventually collapses.
3. The fallen rocks crash into the plunge pool. They swirl around, causing more erosion.
4. Over time, this process is repeated and the waterfall moves upstream.

A steep-sided gorge is formed as the waterfall retreats.
