A)25 degrees Celsius
B)30 degrees Celsius
C)20 degrees Celsius
D)15 degrees Celsius
E)10 degrees Celsius

Question

Quizplus · Accepted Answer

The environmental lapse rate is the rate at which air temperature decreases with an increase in altitude. Given a lapse rate of 5 degrees Celsius per 1000 m, the temperature decreases by 5 degrees for every 1000 m increase in altitude. At 2000 m, the temperature would decrease by 10 degrees (5 degrees/1000 m * 2000 m) from the surface temperature of 25 degrees Celsius, resulting in a temperature of 15 degrees Celsius at 2000 m.
