Using the environmental lapse rate of 3.5°F/1000 feet, if you have a surface temperature of 77.5°F at sea level and go hiking in the nearby mountains to an elevation of 3000 feet, what will the temperature be at that elevation?
A)0°F
B)60°F
C)67°F
D)88°F
E)73.5°F

Question

Quizplus · Accepted Answer

To calculate the temperature at 3000 feet, we need to determine the change in temperature based on the lapse rate.

Change in temperature = lapse rate x elevation change

In this case, elevation change is 3000 ft - 0 ft = 3000 ft

Change in temperature = 3.5°F/1000 ft x 3000 ft = 10.5°F

To find the temperature at 3000 ft, we need to subtract the change in temperature from the initial temperature at sea level:

Temperature at 3000 ft = 77.5°F - 10.5°F = 67°F

Therefore, the correct answer is C.
