Answer
As we go higher upwards, the atmospheric pressure decreases at an average rate of 34 millibars per 300 metres of latitude. It is because the air in the lower layer of the atmosphere is denser than at higher level. The air is denser in lower layer because of gravitational pull of earth and also because the lower layers are compressed under upper layers of atmosphere.
