Explanation:
The air around you has weight, and it presses against everything it touches. That pressure is called atmospheric pressure, or air pressure. It is the force exerted on a surface by the air above it as gravity pulls it to Earth. ... Meteorologists describe the atmospheric pressure by how high the mercury rises.
The earth is surrounded by layer of air called Atmosphere.
The atmosphere is thicker and heavier near the surface of the earth.
As you move upwards away from the ground, the air becomes less dense.
We live at the bottom of this layer.
The air above presses down onus with a force equal to that exerted by a mass of 1 kilo gram, on every square centimeter.
This is called atmospheric pressure.
Atmospheric pressure is the pressure exerted on an object by the weight of the column of the air over it.
