- 1. Multiple Choice
What accounts for the fact that the amount of heating of the Earth’s surface at the geographic poles is less than that which occurs at the tropics?
Compared to the tropics, at the geographic poles more of the insolation is absorbed by the ozone layer above it and only significantly less amount reaches the Earth’s surface.
Compared to the tropics, the angle of incidence of the insolation at the geographic poles causes scattering and or bouncing the incoming energy back into space
Compared to the tropics, the angle of incidence of the insolation at the geographic poles results in a lesser surface heating per square mile.
Compared to the tropics, at the geographic poles more of the insolation is absorbed by the ozone layer above it and only significantly less amount reaches the Earth’s surface.
