Answer to Question 1

ANS: T
The atmosphere at the equator would support cyclone development, but there is not enough
momentum from the Coriolis effect to initiate the spinning motion. Information can be found in the
section Storms Are Variations in Large-Scale Atmospheric Circulation.

Answer to Question 2

ANS: C
Air masses are already characterized as large bodies of air with uniform temperature, humidity, and
density. When air masses pause over land they acquire the characteristics of land. For example, cold,
dry land eventually makes the air mass above it cool and dry. Information can be found in the section
