Why does the amount of water vapour generally decrease with increasing height?
Answer and explanation
Correct answer: Because upper air is colder and farther from the main surface sources
Most atmospheric water vapour enters the air through evaporation from oceans, land and other surface sources. As air rises, it generally cools, causing some vapour to condense into clouds or precipitation. Higher levels are also farther from the main moisture sources. Consequently, water-vapour concentration usually decreases with height, making option A correct.
