Rivers and their tributaries bring silt and deposit it in low lying areas and form plains.

  • Rivers flow down mountain slopes and erode them.
  • They carry them forward.
  • They deposit their load of stones, sand and silt along their courses and in their valleys.

(f) River plains are thickly populated because of the following reasons:

  • Plains are fertile. Agriculture is the main occupation of the people. It can sustain a large population easily.
  • Means of transport are easy to be constructed.
  • Ideal for human habitation due to flat land.

(g) Generally, the plains are flat and made up of fertile soil. So, they provide favorable conditions for agriculture. In plains, rivers flow slowly. Therefore, it can be used for navigation. The construction of the transport network is easy in flat areas. Due to these qualities, the river plains are thickly populated.
