Rivers (features)

Valleys- formed by rivers in different shapes and forms. Eg. steep valleys, broad-shaped valleys, etc.

Rapids- A series of short and fast falls along the course the of a river. They are formed when a river flows over bands of hard and soft rocks.

Waterfalls- A vertical flow of water falling from a great height. It is formed when a river flows over a band of hard rocks overlying softer rocks.

Plunge pools- At the foot of the waterfall, the great force of falling water and the rocks carried by the river cut into the land. A depression at the foot of the waterfall is known as a plunge pool.

  1. along which course of the river (upper/middle/lower) can we find each feature? which process or processes (erosion/transportation/deposition) led to the formation of each feature? :)
