Answer:
Option B) It decreases as someone moves away from earth's surface.
Step-by-step explanation:
The atmospheric pressure at the surface of the earth is at maximum, it is seen that as we move away from the surface of the earth the pressure decreases. As on the top of mountains the atmospheric pressure is found to be low as compared to the surface of the earth.
It is assumed that the atmospheric pressure is caused due to hydrostatic measurements where the changes caused by weight of air are measured.
Also, it is observed that when there is an elevation, the atmospheric pressure decreases.
