Whether the value for atmospheric pressure at the surface of earth is constant or not.

Explanation of Solution
Introduction:
The atmospheric pressure is due to molecules of different gases. Atmospheric pressure is due to weight of the air.
Earth's atmosphere has no definite upper surface. As altitude increases atmospheric pressure decreases. Continuous changes due to storm and wave currents at sea level causes variations in pressure at sea level.
Conclusion:
Atmospheric pressure is not constant at the surface of earth.
