Ans. Most of the plains are formed by the rivers and their tributaries. The rivers flow down the slopes of mountains and erode them. They carry forward the eroded material. Then they deposit their load consisting of stones, sand and slit along their courses and in their valleys. It is from these deposits that plains are formed.
