If water vapour is high in the atmosphere but uplift is absent, why may rainfall not occur?
Answer and explanation
Correct answer: Because cooling for saturation and condensation may remain weak
A high amount of water vapour provides moisture, but moisture alone does not guarantee rainfall. Uplift generally carries moist air to a region of lower pressure, where expansion causes cooling. If uplift and the associated cooling are weak, the air may not reach saturation, condensation may be limited, and cloud droplets may not grow enough to fall as rain. Option B is an absolute false statement; options C and D incorrectly assign rainfall control to nitrogen or ozone.
