Tropical Climates Are Warmer Than Temperate Climates Because

Multiple Choice

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 have more vegetation and thus can absorb more heat.
C) temperate climates are closer to the poles and the polar surfaces cause a reduction in heat gain.
D) 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.
