Answer to Question 1

ANS: B
Areas that have monsoons tend to have wet summers and dry winters. They are connected to
differences in the specific heat of land and water in addition to the seasonal movement of the
intertropical convergence zone. Information can be found in the section Atmospheric Circulation
Generates Large-Scale Surface Wind Patterns

Answer to Question 2

ANS: B
As air rises from the equator, it loses moisture. The drier air then becomes more dense in the upper
atmosphere and falls on its way towards the poles. The air then warms again, continuing the cycle.
Information can be found in the section The Atmosphere Moves in Response to Uneven Solar Heating
and Earth's Rotation
