How does air pressure change with altitude
WebNov 14, 2024 · Why does air pressure change with altitude? At higher elevations, there are fewer air molecules above a given surface than a similar surface at lower levels. Since most of the atmosphere’s molecules are held close to the earth’s surface by the force of gravity, air pressure decreases rapidly at first, then more slowly at higher levels. ... WebAtmospheric pressure varies with the altitude; since the air mass above a certain surface is smaller as we climb up a mountain, air pressure on mountains is usually lower than air pressure at sea level. We can obtain an expression for the atmospheric pressure as a function of elevation.

WebThe ascendance to high-altitude regions coincides with air density and atmospheric pressure declination. The air in elevated areas is accompanied by a low level of dust and moisture. At high altitudes, the short wavelength radiation (ultraviolet and violet) is more prevalent, which does not pass-through lower elevations; as a result, mountain ...
