At approximately what altitude above the surface would be pilot expect the base of cumuliform clouds if the surface air temperature is 82f and the dew point is 38f:
a) 8,000 feet agl
b) 9,000 feet agl
c) 10,000 feet agl
d) 11,000 feet agl

10,000 feet AGL

Explanation:

Hi so we have that the difference of temperature is 82°F – 38°F = 44°F

Now we have that  temperature/dew point spread

So replacing the data we obtain 44°F/4.4°F = approximately 10,000 ft. AGL.

the answer is a. at the equator
