Air exerts pressure in the same way that water exerts pressure on a diver. Air has weight, and because we are at the bottom of a blanket of air that surrounds the earth, the weight of that air is pressing down on us (creating pressure). If ...

Air pressure is the force exerted on you by the weight of tiny particles of air (air molecules). Although air molecules are invisible, they still have weight and take up space. Since there's a lot of "empty" space between air molecules, air can be compressed to fit in a smaller volume.

We are completely unaware of this, but the air is constantly exerting pressure on us, on average this is 14 ¾ pounds per square inch. (1 kg per sq cm). Air molecules are naturally drawn towards the earth by gravity, and as a consequence the density of the air is greater near the surface of the earth.
