Waterfalls & V-Shaped Valleys

WATERFALLS: HOW ARE THEY FORMED?

• For a waterfall to be formed the conditions must first be right. you have you have water running off a edge and a soft rock plunge pool underneath. Firstly the waterfall will cut away at the bottom of the plunge pool and make it deeper. then it erodes (hydraulic action) behind the waterfall. under the constant pressure of the disappearing soft rock, the hard rock would fall into the plunge pool. over thousands of years the water will repeat this process and create a V-shaped valley.
