A)1 degree Celsius per 1,000 m
B)3 degrees Celsius per 1,000 m
C)6 degrees Celsius per 1,000 m
D)9 degrees Celsius per 1,000 m
E)11 degrees Celsius per 1,000 m

Question

Quizplus · Accepted Answer

The environmental lapse rate represents the rate at which air temperature decreases with an increase in altitude. The most unstable atmosphere in a layer of unsaturated air is represented by the highest lapse rate, which is 11 degrees Celsius per 1,000 m, as it indicates rapid temperature decrease with altitude, encouraging air parcels to rise, leading to instability.
