Major Landforms of Earth: Plateau and Plains


A plateau is a flat and elevated land. A plateau is at higher elevation than the surrounding areas. A plateau may have one or more sides with steep slopes. A plateau can be young or old. The height of plateau can be from a few hundred meters to several thousand meters.

Examples: The Deccan Plateau (India) is one of the oldest plateaus in the world. Other examples of plateau are; the East African Plateau in Kenya, Tanzania and Uganda and the Western Plateau in Australia. The Tibet plateau is the highest plateau in the world and its elevation is between 4,000 to 6,000 m above sea level.


Importance of Plateau


Plains are flat lands and are generally not more than 200 m above mean sea level. Some plains are extremely level, while others may be slightly rolling and undulating.

Formation of Plains

Plains are usually formed by rivers and their tributaries. When a river flows down a mountain, it erodes the mountain. The river carries forward the eroded material. Then the river deposits the load in its valley. The load consists of stones, sand and silt. Plains are formed from these deposits.
