Why can the possibility of convective clouds increase when water vapour is high in the troposphere?
Answer and explanation
Correct answer: Warm moist air can rise, cool and condense
The governing concept is convection followed by condensation. When the lower troposphere contains abundant water vapour, warm moist air can rise because of heating and become cooler with altitude. On reaching saturation, the vapour condenses around suitable nuclei and cloud droplets form; continued uplift may produce convective clouds. Nitrogen, ozone, and dust do not explain this direct moisture-and-cooling process, so option A is correct.
