Examine the figure below.Which part of Earth receives the greatest intensity of solar radiation? 
A) Tropic of Cancer and Tropic of Capricorn 
B) equator 
C) North and South Poles 
D) all parts of Earth receive the same intensity of solar radiation.

Quizplus · Accepted Answer

The equator receives the greatest intensity of solar radiation because it is the closest to the sun and most perpendicular to the incoming solar rays. The poles receive less solar radiation because the incoming solar rays are spread out over a larger area, resulting in lower intensity. The Tropic of Cancer and Tropic of Capricorn receive more solar radiation than the poles, but less than the equator because they are not directly perpendicular to incoming solar rays. Therefore, all parts of Earth do not receive the same intensity of solar radiation, and the equator receives the most.
