Question

why does the atmospheric pressure greater on the surface of the earth than in the airplane flying high?​

Answer 1

Air molecules colliding with a surface cause atmospheric pressure. ... Atmospheric pressure decreases as the height of a surface above ground level increases. This is because, as the altitude increases: the number of air molecules decreases.
