Question

Quizplus · Accepted Answer

Clouds have a moderating influence on temperatures because they reflect and absorb incoming solar radiation, creating a cooling effect during the day and trapping infrared radiation, creating a warming effect at night.

Note: A is false because clouds can decrease temperature maximums by blocking incoming solar radiation. B is false because cloud cover varies greatly depending on location and weather conditions. D is also false because clouds can have the opposite effect on temperatures depending on their altitude, thickness, and composition.
