Question

Describe how atmospheric pressure changes as altitude increases?

Answer 1

Ambient temperature at lower temperatures is higher. Air level at lower altitudes is higher. At higher altitudes, there is greater space between air molecules. At the height of a high mountain, there is less oxygen for breathing than there is at sea level.

Answer 2

Pressure with Height: pressure decreases with increasing altitude. The pressure at any level in the atmosphere may be interpreted as the total weight of the air above a unit area at any elevation. At higher elevations, there are fewer air molecules above a given surface than a similar surface at lower levels.
