atmosphere
You might have expected the result to be pressure, but it's not. Pressure occurs due to the bombardment of air molecules on a surface. The weight of a column of air causes so little pressure that it can be considered negligible.
There is air pressure on all sides, inside or outside. The air pressure pushes on the object all ways and nothing falls. If you only apply pressure on the bottom then the object will lift. If you apply pressure on the top, the object will collapse. If air pressure is pushing side ways, the object will move sideways.
This force is called atmospheric pressure, the force is measured per unit area because the bigger the area the more molecules hit. It is 14.7 pounds per square inch ("psi")
Air pressure.
Air pressure
The difference is that Low air pressure has less air molecules pushing down in one area and high air pressure has more air molecules pushing down in one area.

the answer is air pressure
air pressure is the amount of air pushing down on you and high pressure is air that rises.
Air pressure increases at lower altitudes because there is more air above pushing down on the air below. This higher pressure near the ground is due to the weight of the air column above pushing down on it. As you move higher up in altitude, there is less air above pushing down, resulting in lower air pressure.
lower air pressure
The air is always pushing down on you, just slightly more under high pressure. You don't notice it because we've evolved to counter this downward force with an outward force of our own.
Yes, air pressure is greatest at sea level because the weight of the air above is pressing down with more force. As you go higher in altitude, the number of air molecules above you decreases, causing lower air pressure.
atmospheric pressure
A force that is the result of the weight of a column of air pushing down on an area, that is air pressure.
When altitude rises, the air pressure and density both decrease. When temperature rises that means that more air is pushing down on it. So this means that the air pressure and density rise when temperature rises.
