Fill in the blank(s) with correct word
Tropical climates are warmer than temperate climates because
A. temperate climates have more mountains and thus more snow causing the landmasses to warm slower. B. tropical climates receive the sun's rays at a much steeper incidence thus spreading the radiation over a broader area and causing the tropics to be warmer while the temperate climates receive the sun's rays at an almost perpendicular angle, which causes some areas to be warm and other areas to be cold. C. tropical climates receive the sun's rays at an almost perpendicular angle; since Earth is a sphere, the temperate climates receive the sun's rays at a much steeper incidence thus spreading the radiation over a broader area. D. tropical climates have more vegetation and thus can absorb more heat. E. temperate climates are closer to the poles and the polar surfaces cause a reduction in heat gain.
