Regarding latitudinal variations in radiation gain and loss,it is true that:
A)during the Northern Hemisphere summer, the Southern Hemisphere gains more energy than it loses.
B)during the Southern Hemisphere winter, the area of net radiation gain lies north of the equator.
C)global winds are the only significant method for redistributing heat toward the poles.
D)the equator experiences a net radiation loss for six months out of the year.

Question

Quizplus · Accepted Answer

During the Southern Hemisphere winter, the area of net radiation gain lies north of the equator. This is because the angle of incidence of the sun's rays is more direct at the Tropic of Cancer, resulting in more energy absorbed by the Earth's surface in the Northern Hemisphere. The net radiation loss occurs at the equator, where the angle of incidence is at its lowest during this time of year. Global winds do play a role in redistributing heat, but they are not the only method. Option A is false because during the Northern Hemisphere summer, the North Pole experiences more radiation gain than the South Pole. Option D is also false because the equator experiences net radiation gain for most of the year, except during the equinoxes.
