Answer 1

Answer:

⇒The atmosphere is comprised of layers based on temperature. These layers are the troposphere, stratosphere, mesosphere and thermosphere. A further region at about 500 km above the Earth's surface is called the exosphere.

⇒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.

⇒The rajas of mahajanapadas built forts in order to defend their capital city from attacks by other rajas. It is also probable that they wanted to show how rich and powerful they were by building large and powerful walls.
