What contribution can clouds make to energy balance?
Answer and explanation
Correct answer: They can reflect some sunlight and trap some heat
Clouds have a dual influence on Earth’s energy balance. Their bright tops can reflect part of the incoming sunlight back to space, producing a cooling effect, while cloud particles and water vapour can absorb and emit outgoing infrared radiation, producing a warming effect. The net result depends on cloud height, thickness, type, location, and time.
