Question

Quizplus · Accepted Answer

Cumulus congestus clouds have large temperature differences between the bottom and top, which creates instability and allows them to continue growing vertically. This is why they are often associated with thunderstorms and heavy rain. They are not formed in stable air (A) and can be composed of both water droplets and ice crystals (C). While they can have temperatures below -4 degrees Celsius, this is not a defining characteristic (D).
