Question

Give geographical reasons - The proportion of relative humidity changes according to altitude.

Answer 1

Relative humidity expresses the saturation of humidity in the air.

With increasing altitude, the air becomes thin and the atmospheric pressure drops to lower levels gradually.

The humidity that can be held by the air at high altitudes decreases in amounts.

Atmospheric pressure varies with humidity because the air cannot hold high amounts of water vapor in it.

Answer 2

1) the proportion of the water vapour and the temperature varies according to the altitude of a region
2) as we go on higher altitude the amount of water vapour decrease in vice versa
3) the amount of moisture is the highest near the sea level because of high temperature
