Waterfall

Waterfall

The waterfall can be formed due to water flowing over the various types of rock layers that have different hardness. Water flowing on hard rock will result in a slow process of erosion, while the soft rock will cause rapid erosion rate, so that it will produce a steep stream of water on a hard rock. Gravity also increase the speed of the water, where the water will flow from a high to lower place. Eventually, the watercourse steepens until it’s either nearly vertical or completely vertical, forming a waterfall.
