How are waterfalls formed in detail

A

Waterfalls occur when rivers flow over different types of rock. The soft rock wears away faster than the hard rock. In time a step develops over which the river plunges as a waterfall.water also cuts away rock behind the waterfall. This causes the falls to move back and leave a gorge as it goes
