Question 2 • **MFISD ENVIRONMENTAL SYSTEMS B 22-23 CR
As part of the greenhouse effect, Earth’s surface radiates heat back into the atmosphere and the atmosphere absorbs this heat. Why do areas near the equator generally radiate more energy back into the atmosphere than areas near the poles?
Answer
A
Areas near the equator have more clouds in the atmosphere than areas near the poles.
B
Areas near the equator receive more incoming solar energy than areas near the poles.
C
The greenhouse effect only occurs near the equator.
D
The greenhouse effect only occurs near the poles.
Explanation
Areas near the equator receive more direct sunlight throughout the year than areas near the poles. This gives the equatorial surface more energy to warm up and radiate as heat back into the atmosphere. The greenhouse effect occurs around the globe, so it is not limited to either region.
