The four fundamental force types are : 1.Gravitational force 2. Electromagnetic force 3. Weak force 4. Strong force (nuclear force)
Yes. The term is a compound noun, and both air and pressure are nouns. Air pressure is the measure of the force exerted by the weight of the atmosphere pushing down on the Earth.
The four fundamental forces of nature are Weak nuclear force, Strong nuclear force, Electromagnetic force and Gravitational force.

Atmospheric pressure is caused by the force of the air above the earths surface. It is measured by the point in which the air meets the atmosphere.
The pressure increases as the atmosphere gets deeper. At lower levels of the atmosphere there is more fluid above that is being pulled by Earth's gravitational force .So, there is more pressure at lower levels of the atmosphere.
Force exerts pressure. For example: At the surface of the Earth the column of air in the atmosphere above an area has a mass that exerts a force (due to gravity) on that surface area.
force = pressure x area , so pressure is force divided by area, air molecules stack up on top of each other and the force of them (caused by gravity and their mass ) weighs down with a pressure of 14.7 lbs/sq inch or 1 bar. As you go higher the stack is lower so the pressure drops until you get to space and it measures a vacuum.
