Answer to Question 1

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.

Answer to Question 2

ANS: B
The exceedingly low pressure at the center of the storm generated an enormous storm surge. The
damage was compounded by the failure of some levees. Information can be found in the section The
Atlantic Hurricane Season of 2005 Was the Most Destructive Ever Recorded.
