Difference between Erosional and Depositional plains
|
Depositional Plains |
Erosional Plains |
|---|---|
|
These plains are formed by the deposition of the soil and other material by the wind, rivers or glaciers. |
These plains are formed by the erosion action of the rivers, wind and glaciers. |
| They are replenished every year by the rivers and are also called floodplains if they are formed due to the flooding of the rivers. |
These plains take a long time to form as the upper rock material erodes very slowly over a long period of time. |
|
The depositional plains formed by the action of wind are called Loess. |
The erosional plains formed by the action of wind are called Pediplains. |
|
The depositional plains formed by the action of rivers and glaciers are called flood plains and glacial plains respectively. |
The action of rivers and glaciers leads to the formation of erosional plains which are called Peneplains. |
|
The Northern Plains of India is an example of the depositional plains. |
The Plains of Canada and the Niagara Plains of the USA are an example of the erosional plains in the world. |
Describe the Formation of Erosional Plains.
Plains are large, flat and level pieces of land. They are generally very fertile in nature and support the growth of crops and other plants which are useful to humans. Plains generally have a large amount of population due to various reasons such as easy terrain, more opportunities, fertile land and availability of good lifestyle and climate. Thus plains are an important landform in geography. India has plains to its North and North-East parts which are called the Northern Plains. These plains are very fertile and are formed by the Ganga and Brahmaputra along with their tributaries. These plains stretch from Punjab, Haryana, Uttar Pradesh, Bihar, Jharkhand and West Bengal. Northern plains have nearly 60% of the total population of India. Apart from these India also has coastal plains along the Western and Eastern coasts called the Western and Eastern coastal plains respectively.
