Waterfall

A cascade of water falling from a height, formed when a river or stream flows over a precipice or steep incline.

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

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.
