If you were to drill a hole in the ground, what is the expression for the air pressure below ground? Above ground it is exponential with distance (at least to an approximation), so what is it for below Earth's surface?
It has to increase but probably with a lesser absolute slope than above ground. Let's assume the usual "earth is a perfect sphere with uniform density" and that the air is isothermal.
