The relationship between air pressure and elevation is nonlinear because:
A)air is compressible.
B)air pressure changes with elevation.
C)the equation of state is an exponential function.
D)There is no clear relationship between temperature and elevation.

Question

Quizplus · Accepted Answer

Air is compressible, which means that as elevation increases, the air becomes less dense and the pressure decreases in a nonlinear manner.
