Question

how are plain form? why are the river plains thickly populated? in short ans​

Answer 1

Answer:

Plains form in many different ways. Some plains form as ice and water erodes, or wears away, the dirt and rock on higher land. Water and ice carry the bits of dirt, rock, and other material, called sediment, down hillsides to be deposited elsewhere. As layer upon layer of this sediment is laid down, plains form.

Plains are usually highly fertile and hence most ideal for cultivation. It is very easy to make transport network in the plains. Hence, plains are thickly populated.

Answer 2

Answer:

the plane forms are highly populated due the fertile soil around the river banks which serves as good nutrition and yields healthy crops
