Relative humidity of the atmosphere is directly affected by ________

Solution (By Examveda Team)

Relative humidity of the atmosphere is directly affected by change in atmospheric pressure. Relative humidity is directly related to the amount of water vapor in air, and that's the relationship. The more is the water vapour in the air, the higher the relative humidity is at a given tempera- ture. Air with a relative humidity of 50% contains half of the water vapor it could hold at a particular temperature.
