Water vapour turns into clouds in the atmosphere when:
Correct answer: C. Dew point is reached
- A. It rains
- B. The temperature rise
- C. Dew point is reached
- D. Evaporation takes place
Explanation
As moist air cools to its dew point, it becomes saturated and water vapour condenses on tiny particles to form cloud droplets or ice crystals. Rain is a later possible result, not the condition that starts cloud formation.
