There are two types of waterfall:
1.CataractsWaterfall
2. Cascade Waterfall
Cataracts Waterfall : Cataracts are found where there are many rapids in a large river and large volume of water flows down from this rapids.
Cascade Waterfall : Cascade waterfalls have a small volume of water. A series of falls may form one waterfall.
Formation of Waterfall:Hard Rock covers the soft rock. Water flows on soft rock.Overtime the soft rock is eroded more and more by the force of water flowing over it. This makes a cliff which the water topples over it.At the bottom of the cliff some water splashes onto the cliff and makes a plunge pool by a process called 'undercutting '.
Plunge Pool: A plunge pool is found at the bottom of a waterfall. A large pothole is formed by the water swirling and throwing boulders and stones around in circles.There is a lot of spray in a plunge pool at the bottom of a very large waterfall.
