Depending on the change of sea level, river flow, and geology (among other factors), falls or rapids may develop at the knickpoint. Many waterfalls have been created by glaciation where valleys have been over-deepened by ice and tributary valleys have been left high up on steep valley sides.
What causes waterfalls to form?
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 fallen rocks crash into the plunge pool . They swirl around, causing more erosion.

Why do waterfalls not run out of water?
In the case of major rivers, they usually don’t run out of water because they drain a very large area of land. Rain will make its way to a major river from miles around, so even relatively small rainfalls can lead to a large volume of water going into a single river. Some major rivers do run dry, though.
What are the characteristics of waterfalls?
One of the characteristic features associated with waterfalls of any great magnitude, with respect to volume of flow as well as to height, is the presence of a plunge pool, a basin that is scoured out of the river channel beneath the falling water.
