Answer 1

Answer:

Mountains are a storehouse of water. Water from the mountains is also used for irrigation and generation of hydro-electricity. The river valleys and terraces are ideal for the cultivation of crops.

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.
