Why does the heat budget vary with latitude?
a. The angle of the sun at varying latitudes
b. The proximity to magnetic poles
c. Atmospheric circulation currents disperse solar radiation
d. The axis of the Earth
ANS: A
There is a difference in the amount of heat budget at different latitudes. This is from the angle the sun's
radiation is hitting Earth's surface. Polar latitudes have the sun approaching from low angles so the
radiation spreads over a greater area. Tropical latitudes have radiation coming from a nearly vertical
angle which lowers the distribution area. Information can be found in the section The Atmosphere
Moves in Response to Uneven Solar Heating and Earth's Rotation.
