Answer:

plains are formed by both external and internal processes.the plains like the great plains of USA were formed by the upliftment of a part of land under the sea are known as structural plains.In the middle,the course of the river begins to over flow its banks. in this process, the materials being carried by the river are sand,clay and slit, together called the alluvium. these get deposit in the flood plains, also called the alluvial plains.
