Question

Describe the heat zones of the earth with the help of a diagram.

Answer 1

On the basis of the amount of heat received by a particular place, the Earth is divided into the following three heat zones:

1. Torrid zone: This is the hottest zone that extends from 0° to 23 1/2° N and S and receives the maximum amount of sunlight. The sunrays are perpendicular to this zone.

2. Temperate zone: In this zone, sunrays are slanting and hence, the zone is neither too cold nor too hot. The climate in this zone is moderate. It extends from 23 1/2° N to 66 1/2° N and 23 1/2° S to 66 1/2° S.

3. Frigid zone: Here, the sunrays are very inclined so this zone receives the minimum amount of sunlight. Hence, it remains the coldest zone. It extends from 66 1/2° N​ to North Pole and 66 1/2° S​ to South Pole, respectively.
