Question

How does the atmospheric pressure vary with altitude?​

Answer 1

Step-by-step explanation:

In most circumstances, atmospheric pressure is closely approximated by the hydrostatic pressure caused by the weight of air above the measurement point. As elevation increases, there is less overlying atmospheric mass, so that atmospheric pressure decreases with increasing elevation.

Answer 2

At heights the atmosphere is not dense, so, the atmospheric pressure at heights is less as the mass of air is less. But opposite to heights and sea level the mass of air is more as the atmosphere is dense; thus, increasing the atmospheric pressure.
