Which of the following sets of conditions would produce a cumulus cloud with the lowest base?
A) air temperature 90 F,dew point temperature 50 F
B) air temperature 90 F,dew point temperature 40 F
C) air temperature 90 F,dew point temperature 60 F
D) air temperature 90 F,dew point temperature 20 F

Question

Quizplus · Accepted Answer

The base of a cumulus cloud is determined by the difference between the air temperature and the dew point. The smaller the difference, the lower the cloud base. Option C has the smallest temperature-dew point spread (90°F - 60°F = 30°F), resulting in the lowest cloud base.
