Question

What is the reason behind the prevalence of high pressure on dry air than moist air?​

Answer 1

Explanation:

In the atmosphere, the dry air exerts more pressure than most air. As dry air consists mostly of nitrogen and oxygen and other gases which exerts high pressure on the other hand in moist air-water vapour contain increases, the weight of which is less than nitrogen and oxygen. So moist air is lighter than dry air.
