Atmospheric water vapour may reach about four percent under what type of condition?
Answer and explanation
Correct answer: In warm and very humid air
The governing concept is that warm air can contain more water vapour than cold air, while actual humidity also depends on the availability of moisture. In warm, very humid conditions near moist surfaces, water vapour can form a much larger fraction of air and may approach about four percent. Therefore, option A is correct. Dry polar and desert air contains little vapour, and the upper stratosphere is also extremely dry.
