Question 2Sinking air sometimes cools adiabatically.
a. True
b. False
Question 3The temperature of rising air at a given level inside a cumulus cloud is normally warmer than the air around the cloud.
a. True
b. False
Question 4Convective instability associated with severe thunderstorms and tornadoes can be brought on by lifting a stable air layer whose surface is humid and whose top is dry.
a. True
b. False
Question 5The combination of warming the surface and warming the air aloft creates the greatest atmospheric stability.
a. True
