Question

Quizplus · Accepted Answer

I and II are correct. High-energy solar radiation does enter the atmosphere, and some of this energy is indeed reflected while some is absorbed by the Earth's surface. However, III is incorrect because the greenhouse effect actually involves the retention of heat in the atmosphere, which increases, not decreases, the temperature on Earth.
