Waterfalls 101

Waterfalls are formed by a continuous process of erosion. Over time the flowing water eats away at the rock’s surface, together there are two types of rocks beneath the water level; soft and hard. The soft rock begins eroding quicker than its counterpart as the flowing water carries sediments that overtime cut into the soft rock. Therefore, a vertical drop in the ground is created. When the flowing water approaches the drop its velocity increases which heightens the under layer erosion as well.
