Is atmospheric pressure the same everywhere on the surface of the earth?

Atmospheric pressure differs in different parts of the world.

Explanation:

This is because atmospheric pressure depends on the height of a particular location on earth. A number of locations on the earth are at sea level. The atmospheric pressure at sea level is 14.7 pounds per square inch. At higher levels (altitudes) the atmospheric pressure is lower since higher places have got less air pushing downwards compared to lower altitudes which have more air pushing down and hence, high atmospheric pressure.
