alleryWhy does rising water vapour condense into cloud droplets?
AIt warms up as it rises
BIt cools as it rises higher
CIt meets the sea surface
DIt loses all its mass
Answer & Solution
Correct answer: B. It cools as it rises higher
1. Air pressure decreases as altitude increases.
2. This causes a drop in temperature, so the vapour condenses into droplets.
3. Warming would keep it as vapour, and it never loses its mass.
