What temperature will be at the surface of the earth if it is -13 degrees Celsius at an altitude of 2.9 km?

To solve the problem, it should be remembered that with a descent for every 100 meters, the air temperature drops by approximately 0.6 ° C. Consequently, it decreases by 6 ° С every 1 km. Thus, it is possible to calculate how the air temperature will change with decreasing altitude. To do this, perform the following action:

2900 ÷ 100 = 29 ° С – the air temperature will decrease.

Hence,

-13 – (-29) = -13 + 29 = + 16 ° C.

Therefore, we can conclude that the air temperature on the Earth’s surface will be + 16 ° C.
