Air pressure is the force exerted by the gases in the atmosphere as Earth's gravity pulls on it. The atmosphere can be thought of as a 'sea' of gas surrounding the planet.
Air pushes against us from all directions as the weight of air above compresses the air below (this is why altitude affects air pressure.)

How does atmospheric pressure change as you move away from the surface of earth?
Air pressure decreases as you move away from Earth's surface.
Why is air pressure greatest at the Earth's surface (the Troposphere answer?
The air above it weighs it down.
What strongly affects the movement of air masses along the earth's surface?
The differences in air pressure and the Earth's rotation.
Why is air pressure greatest at the Earth's surface?
Because as you get closer to the surface of the earth, the more air that is on top of you. At the top of the atmosphere, there is no air, and everything is a vacuum, where you have no weight. When you get close to the earth, the weight of the air builds until it when you're at the very lowest point of the earths surface, all the air in the atmosphere above you is pressing down.
Earth's surface winds generally blow from regions of higher..?
air pressure
Why does the air exert pressure on the surface of the earth?
Air produces a force on the surface of an object (in this case the earth) because of the movement of the particles that make up air. This force over a defined area is known as pressure.
Dose air in the atmosphere exert pressure on earths surface?
Yes. Atmospheric pressure is the pressure caused by air when it exerts pressure on the surface of earth.
What happens to air pressure as distance from earth's surface increases?
the air pressure increases
What air pressure is caused by?
Air pressure is caused by the unequal heating of earth's surface.
How does the air pressure at the surface of the earth compare to the air pressure at about 7 miles above earth?
The greater the altitude, the lower the air prassure.
Explain what hppens to air pressure as you move away from the earths surface?
Pressure increases as you get closer to earth.
How does atmospheric pressure change as you move away from the surface of earth?
Air pressure decreases as you move away from Earth's surface.
The weight of the air on the earths surface is?
The weight of the air on the earth is called... Air Pressure
Why is air pressure located near earth's surface?
because there is no air in space.
What is the measure of the force with which air molecules are pushing on the Earth's surface?
Air Pressure
