Briefly state the variations in the vertical distribution of pressure.

उत्तर
Many factors like the slope of the land, presence of winds, and the temperature affect the pressure of air vertically. The rate of decrease is 100 millibars per 1000 meters of height gained. There is a thin air cover at high altitudes, so the percentage and amount of oxygen are also less.
