Answer to Question 1

ANS: B
As air is subjected to less pressure, air expands. This expanded air is cooler than air that has been
compressed. The cooling of air occurs at higher altitudes where less pressure is exerted on the air.
Information can be found in the section The Atmosphere Is Composed Mainly of Nitrogen, Oxygen,
and Water Vapor



Answer to Question 2

ANS: C
Vilhelm Bjerknes realized tropical cyclones form due to disturbances within a single warm and humid
air mass. He also concluded extratropical air masses form between two air masses. Information can be
found in the section Storms Are Variations in Large-Scale Atmospheric Circulation
