The Main Reason Polar Regions are Cooler Than the Equator

Question

The main reason polar regions are cooler than the equator is that
A)there is more ice at the poles.
B)sunlight strikes the poles at a lower angle.
C)the poles are farther from the sun.
D)the polar atmosphere is thinner and contains fewer greenhouse gases.
E)the poles are permanently tilted away from the sun.

Accepted Answer

Sunlight strikes the poles at a lower angle, which means the same amount of energy is spread over a larger surface area, resulting in cooler temperatures compared to regions closer to the equator, where sunlight strikes at a more direct angle.
