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.

The force exerted by the weight of a column of air on a surface is called?
Air Pressure The force exerted by the air above is called?
What is an air column?
the weight of a column of air above you that puts pressure on you
Does air pressure decrease with increasing altitudes?
No, air pressure decreases with increasing elevation. This is because air pressure is due to the weight of the column of air above where you are. The higher you go, the less air there is above you, so the less the weight of that column of air and the lower the air pressure.
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.
What produces air pressure at the surface of the earth?
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.)
What is The force on a given area by the weight of air above it?
Downforce
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 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.
What is the force put on a given area by the weight of the air above it called?
Atmospheric pressure.. maybe
Why dosen't the weight of air above a table crush it?
because the table exerts the same amount of force
What is the definition of atmospheric pressure?
Air pressure is the force (weight of Earth's atmosphere) exerted on you by the weight of tiny particles of air, the air molecules above and around you. This is also referred to as "barometric pressure" (measured with a barometer) and will change with altitude or elevation. The standard pressure is 1 ATM (atmosphere), equal to 101325 pascals or 1013.25 mbar.
The force exerted by the weight of a column of air on a surface is called?
Air Pressure The force exerted by the air above is called?
What is the mo-to of the US air force?
The motto of the United States Air Force is "Above All".
Which is not a force weight air friction resistance momentum?
Momentum is not a force.
What is air pruessure?
The weight of air above us in the atmosphere
