Which of these processes as a cooling affect on earth? (apex)

The answer is A. Evaporation of water due to warmer temperature causes low thick clouds.

Explanation:

Evaporation is the process in which liquid is changed into gas due to increases temperature or pressure. It is an important part of water recycling in nature. water from sea, rivers and streams evaporate and form clouds which brings water back to earth by raining. Evaporation also causes cooling effect as during evaporation heat is absorbed from the environment. On the other hand the cloud formation and rain also induce cooling by bringing down the temperature.
