Thunderstorms and large cumulus clouds are characteristic of:
A)all polar air masses.
B)isothermal lapse rates.
C)all warm fronts.
D)unstable air.
E)stable air.

Question

Quizplus · Accepted Answer

Thunderstorms and large cumulus clouds occur in unstable air, where warm and moist air rises quickly and creates strong updrafts. This instability can be caused by factors like heating of the surface, mixing of different air masses, or the presence of a cold front. The other choices are incorrect: polar air masses can be stable or unstable depending on the temperature and moisture content; isothermal lapse rates are not directly related to storms and clouds; warm fronts are associated with gradual lifting of warm air rather than sudden instability; and stable air tends to resist vertical movement and does not produce storms easily.
