Explain the formation of a waterfall, describe the processes that happen in the making of this landform.

Waterfalls are ususally found in the upper section of the river course, this is because the bedrock in upper sections is of different degrees of hardness, composed of both hard and soft rock. The main processes involved is erosion, as the softer rock is eroded faster which creates the waterfall. softer rock is eroded faster leading undercutting hard rock is left overhanging and isn't supported anymore, leading to collapse.where the rock collapses a plunge pool is created which causes more erosion overtime, erosion will continue to wear away the rock and a gorge is formed, as the waterfall retreats.
