Which of the following describes the conditions when ordinary thunderstorms, which last about one hour only, begin to dissipate?
A)The downdraft spreads throughout the cloud and cuts off the updraft.
B)All precipitation particles in the cloud turn to ice.
C)Solar heating at the ground begins to decrease.
D)Lightning neutralizes all the electrical charge in the cloud.

Question

Quizplus · Accepted Answer

Ordinary thunderstorms rely on a cycle of warm updrafts and cool downdrafts. As the storm progresses, the downdrafts grow stronger and mix with the updrafts, cutting off the supply of warm air and causing the storm to weaken and dissipate.

Answer: C 
 Thunderstorms need warm, moist air to form and sustain themselves. If the solar heating at the ground decreases, the warm air will quickly cool and become less conducive to storm formation. This can cause ordinary thunderstorms to dissipate.

Answer: B and D are not correct. All precipitation particles turning to ice would lead to an increase in electrical charge in the cloud, rather than a decrease. Additionally, while lightning can neutralize some electrical charge within a cloud, it is not the primary cause of thunderstorm dissipation.
