Question

Cooling temperatures and high humidity promote which stage of the water cycle?

Answer 1

Answer is: condensation.
Condensation of water is the change of the physical state of water from gas phase into liquid phase or change in the state of water vapor (vapor is cooled  to its saturation limit) to liquid water when in contact with a liquid or solid surface, for example clouds (cloud condensation nuclei).

Answer 2

Condensation is the stage of water cycle which is affected by cooling temperatures and high humidity.

Answer: Option A

Explanation:

Condensation is the process which involves cooling down of the water vapor at low temperatures in the atmosphere. When the temperature is low or cool and there is high humidity, condensation takes place at a higher rate.

Condensation results in precipitation. High humidity means more water vapor is present in the atmosphere and therefore more of condensation will take place.
