Question
'The height of troposphere is not even from the earth’s surface'. Discuss.
Solution
The height of troposphere is not even from the earth’s surface. It is 9 to 10 km over the poles and 17 to 18 km on the equator. It is due to the difference of amount of insolation received on the equator and poles. The equator receives a more amount of insolation as compared to poles. This amount of insolation increases the temperature in the equatorial belts. The high temperatures of this belt heat the winds. The heated winds become lighter and ascend in the form of convectional air currents. These currents push the layers to great heights. In this way, the troposphere is high at the equator.
