Is a waterfall river deposition?
Waterfalls are formed as a result of vertical erosion in the upper course of a river through the processes of Hydraulic Action, Abrasion and Solution. A waterfall usually develops where a band of hard rock lies across a band of soft rock on the river bed. This is known as differential erosion.
What are 2 landforms formed by river deposition?
Erosion and deposition within a river channel cause landforms to be created: Potholes. Rapids. Waterfalls.

What are the 10 types of waterfalls?
Waterfalls are classified into 10 different types depending on the way they descend. Some prime examples are Punchbowl Waterfalls, Plunge Waterfalls, Multi-step Waterfalls, Horsetail Waterfalls, Frozen Waterfalls, Fan Waterfalls, Chutes, Cataracts, Cascades, and Block Waterfalls.
How are waterfalls formed by erosion and deposition?
Waterfalls Formation of a waterfall The river flows over bands of less resistant (softer) and resistant (harder) rocks. The less resistant rock is more quickly worn away due to differential erosion.
Where are waterfalls most likely to be formed?
Most often, waterfalls are formed in the upper course of rivers. This is the place where lakes start to fall into steep areas, such as mountains. Many waterfalls form over bedrock that is not assisted by the surrounding area due to their landscape positioning.
What happens to the rocks after a waterfall?
After the overhang falls, some of the rocks are swirled around by the river and this helps to form a deep plunge pool below the waterfall. The plunge pool is also deepened during times of high discharge when hydraulic action is most powerful.
How does the overhang of a waterfall form?
The river undercuts the harder rock leaving an overhang which becomes unsupported and collapses into the plunge pool below. After the overhang falls, some of the rocks are swirled around by the river and this helps to form a deep plunge pool below the waterfall.
