13: Insolation
- #5With the help of a diagram, show the heat zones of the earth and write briefly about each of them.Ans :
Torrid Zone : It lies between 23 1/2° N and 23 1/2° S latitudes. This zone receives maximum temperature due to vertical rays of the sun and maximum rainfall.
Temperate Zone : It lies between 23 1/2° N - 66 1/2° N and 23 1/2° S - 66 1/2° S. It is known for medium temperature and rainfall due to slanting rays of the sun. 3.
Frigid Zone : It lies between 66 1/2° N - 90° N and to 66 1/2° S - 90° S. The sun’s rays are slanting and have to cover a very large distance. Besides this, inspite of long summer covering 6 months, the sun’s heat is immediately reflected back by the snow cover. So, the temperature is extremely low and cold Blizzards (icy winds) blow from Poles towards Arctic and Antarctic circles. The coldest place on the face of the earth is Varkhoyansk (-58°C) in N.E. Siberia. Although the temperature in Antarctic may be -94°C, but there is no habituated place, (as the definition of a place is the area inhabited by people).
