Question 1197Navigation General70% to pass
A sign of thunderstorm development is a cumulus cloud _______________.
AI Explanation
The correct answer is D) All of the above.
This is the correct answer because all three conditions indicate the development of a thunderstorm. A cumulus cloud showing extensive vertical development, darkening and growing in size with an anvil top, and creating cold downdrafts felt on the ground are all signs of a thunderstorm forming. These characteristics are consistent with the rapid upward movement of air, condensation, and the release of latent heat that occurs in the thunderstorm formation process. The other options are incorrect because they do not fully encompass the various visual and physical indicators of a developing thunderstorm.
