Atmospheric pressure decreases as the height of a surface above ground level increases. This is because, as the altitude increases:
•the number of air molecules decreases
•the weight of the air decreases
•there is less air above a surface
This is why aircraft that fly at high altitudes must be pressurised. If the air pressure is too low, humans cannot take in oxygen quickly enough to meet their bodies’ needs.
