Question

What are Plains? How are they formed?

Answer 1

Plains are large stretches of flat land. They are, generally, not more than 200 metres above the mean sea level.

Most of the plains are formed by rivers and their tributaries.
i) When the rivers flow down the slopes of the mountains, they chip away at the rocks. Over time, these rocks break into smaller pieces.
ii) The rivers then carry these pieces and deposit these loads consisting of stones, sand and silt along their courses and in their valleys.
iii) It is from these deposits that plains are formed.
