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.
The second, or the external process is the continuous wearing down and rebuilding of the land surface. Thewearing away of the earth's surface is called erosion. The surface is being lowered by the process of erosion andrebuilt by the process of deposition.
