Question

Air becomes saturated. (geographical reasons)

Answer 1

Hi friend here is your answer

#######################

Air at a certain temperature can hold a wide range of water vapor. When there is a lot of water vapor available the relative humidity rises. This is a reading of the moisture in the air compared to what it could hold, relative humidity. When the air can hold no more it is said to have reached its saturation point, or dew point.

Answer 2

When a volume of air at a given temperature holds the maximum amount of water vapour, the air is said to be saturated. Relative humidity isthe water vapour content of the airrelative to its content at saturation.
