Final answer:
An intense thunderstorm has cooler cloud tops due to the strong updrafts that push the cloud tops higher into the atmosphere where it is colder.
This correct answer is d)
Step-by-step explanation:
An intense thunderstorm will have a relatively cooler cloud top. Thunderstorms are powered by convection, where warmer air rises and cooler air sinks.
The intensity of a thunderstorm is often associated with strong updrafts that push the cloud tops higher into the atmosphere where the temperature is colder.
Therefore, the cloud tops of intense thunderstorms tend to be higher and cooler due to the expansion and cooling of rising air at lower pressures aloft.
This correct answer is d)
