That is the air pressure or amospheric pressure. It is the pressure at any given point in the Earth's atmosphere. In most circumstances atmospheric pressure is closely approximated by the hydrostatic pressure caused by the weight of air above the measurement point. Low pressure areas have less atmospheric mass above their location, whereas high pressure areas have more atmospheric mass above their location. Similarly, as elevation increases there is less overlying atmospheric mass, so that pressure decreases with increasing elevation. A column of air 1 square inch in cross section, measured from sea level to the top of the atmosphere, would weigh approximately 14.7 lbf. A 1 m² (11 sq ft) column of air would weigh about 100 kilonewtons, equivalent to a mass of 10.2 tonnes at the surface.
What else can I help you with?
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.
Why does Atmospheric pressure exists because air has what?
Atmospheric pressure exists because air has weight. The weight of the air above exerts a force on the air below it, resulting in pressure at the Earth's surface.
What is the push of air on the Earth called?
The push of air on the Earth is called atmospheric pressure. It is the force exerted by the weight of the air above a given point on Earth's surface.
What is atmospheric pressure based on?
What do you mean "... based on"? The athmosperic pressure is "weight of air" and it can be measured. Strikly speaking: "force per unit area exerted against a surface by the weight of air above that surface at any given point" (wikipedia) Ap could be given in force/area units for example lb/sq ft, kg/sq meter etc.
Weight is the result of air pressure exerted upon an object?
Weight is the force of gravity acting on an object's mass, not air pressure. Air pressure is the force exerted by the atmosphere on objects. Weight depends on the mass of the object and the acceleration due to gravity, while air pressure depends on the density of air and the height above sea level.
The force exerted by the weight of air above is called what?
The force exerted by the weight of the air above is called atmospheric pressure.
What is the force exerted by the weight of the air above is said to be?
The force exerted by the weight of the air above is called atmospheric pressure. It is the pressure exerted on Earth's surface by the weight of the air in the atmosphere above it.
What is The force on a given area by the weight of air above it?
Downforce
What is the force put on a given area by the weight of the air above it called?
The force put on a given area by the weight of the air above it is called atmospheric pressure.
The weight of air is called?
The weight of air is called atmospheric pressure. It is the force exerted by the weight of the air above a given point in the atmosphere.
What force on an object is caused by the weight of the air above the object?
gravity
What is the force put on a given area by the weight of air above it is?
Downforce
What is the force that air exerts on your body called?
The force that air exerts on your body is called air pressure. This force is a result of the weight of the air above you pressing down on your body.
When air exerts a force it is called?
When air exerts a force, it is called air pressure. Air pressure is the force exerted by the weight of air above a given point.
What is the force exerted by the weight of the air is called what?
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.
What force put on a given area by the weight of the air above it is called what?
Atmospheric pressure
The force put on a given area by the weight of the air above it?
The atmospheric pressure at that place and at that time.
