$1.$ Coastal Plains:
- Plains near the sea coast are known as Coastal plains.
- Such plains are formed by the upliftment of continental shelf areas.
- Their slope is seawards.
- Rivers bring alluvium from the interior of continents and deposit in such plains to make them flat.
- Sometimes coastal plains are formed by erosion also.
- Due to saline soils, such plains are mostly useless for agriculture.
- Such plains are Malabar in India and cast coast plains of Japan.
- Forces of denudation and erosion such as river, glacier and wind play a role in the formation of such plains.
- Due to continuous erosion work of mobile forces, mountains and plateaus get eroded and flattened.
- Soft rocks are rapidly eroded, while hard rocks are eroded slowly at their places.
- Such plains are known as Peneplain.
- Dynamic forces are deposited by river, snow river and wind.
- They deplete as their carrying capacity decreases and thus deposition plates are formed.
