Question

Quizplus · Accepted Answer

The Earth's annual net radiation budget is positive from the equator to about 40ᵒ north and south, which means more solar radiation is received than emitted. Beyond 40ᵒ north and south, the net radiation budget is negative, which means more radiation is emitted than received. This is because the polar regions receive less intense solar radiation due to the oblique angle of incidence, and hence radiate more heat back to space than they receive from the sun.
