the answer is air pressure
kung wubba
The weight of the air pushing down on Earth's surface is due to air pressure, which averages around 14.7 pounds per square inch (psi) at sea level. This pressure is caused by the force exerted by the weight of the air molecules in the atmosphere above.
A force that is the result of the weight of a column of air pushing down on an area, that is air pressure.
the average at sea level is 14.7 psi. "weight" of air is referred to as atmospheric pressure.
Air pressure, barometric pressure, the boiling point of water.
The force exerted by the weight of the air is called atmospheric pressure. It results from the weight of the air above pushing down on the air below, creating a pressure gradient that affects weather patterns and influences the movement of air masses.
The force that air exerts on the surface of the Earth is called atmospheric pressure. It is caused by the weight of the air above pushing down on the surface.
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.
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.
Gravity causes air pressure by pulling air molecules towards the Earth's surface. The weight of the air above creates pressure on the air below it. The higher you go, the lesser the air pressure due to less weight above pushing down.
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.
