What is the temperature of the air at the surface of the Earth, if at an altitude of 4 km it is -10 ° C?

To determine what will be the temperature of the air at the surface of the Earth is not particularly difficult. The main thing in this matter is to understand that as the distance from the surface increases, the temperature will decrease. Scientists have experimentally established the fact that for every kilometer the top temperature drops by about 6 degrees. Accordingly, this problem is solved as follows:
-10 + 4×6 = 14
It turns out that the temperature at the surface is +14 degrees.
