Air pressure is the force exerted on you by the weight of tiny particles of air (air molecules). Although air molecules are invisible, they still have weight and take up space. Since there's a lot of "empty" space between air molecules, air can be compressed to fit in a smallervolume.
When it's compressed, air is said to be "under high pressure". Air at sea level is what we're used to, in fact, we're so used to it that we forget we're actually feeling air pressure all the time!
Weather forecasters measure air pressure with abarometer. Barometers are used to measure the current air pressure at a particular location in "inches of Mercury" or in "millibars" (mb). A measurement of 29.92 inches of mercury is equivalent to 1013.25 millibars.
How much pressure are you under? Earth's atmosphere is pressing against each square inch of you with a force of 1 kilogram per square centimeter (14.7 pounds per square inch). The force on 1,000 square centimeters (a little larger than a square foot) is about a ton!
Why doesn't all that pressure squash me? Remember that you have air insideyour body too, that air balances out the pressure outside so you stay nice and firm and not squishy.

What is the weather term of how heavy the air is?
Air Pressure
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?
Air has pressure because air has?
Air has pressure because air has mass and weight.
Why would air pressure be important to people who raise fruit?
because they need it
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.
How was air pressure put in first air gun?
with a hand pump
What is the force put on a giving area by the air above?
Air pressure
How do you turn off tire pressure alarm?
put air in the tire
What is high pressurs?
If you mean by air pressure, High air pressure is how much air there is upon you. IF you were on the death valley, you would have lots of air pressure. If you were on a mountain, there would be little air pressure. If there is high pressure, there is good weather If you mean the other pressure, then it is this. If there is a lot of pressure, then you are intimidated, and there is lots of people looking at you. Visa Versa for low pressure.
Where do you put freon in a Ford Explorer Eddie Bauer?
You can put Freon into your air conditioning system through the low pressure port. The low pressure port can be found on the top of your air conditioning compressor.
Does air pressure tell you how heavy air is?
Yes because when when you put a balloon in the air the balloon will tell you if its heavier or lighter.
Why is there air at the top of soft drink cans?
the air is there because the cans are flexible, and most people put pressure on the sides to open them. If there was no air then soda would spill out easily. It also allows the soda companies to put slightly less liquid thanis actually stated on the can.
Why does air pressure decrease as altitude increase?
The atmoshere is held around the earth by gravity. Gravitypulls gas molecules in the atmosphere towards the earth'ssurface causing air pressure. air pressure is the measure of the force with which air molecules push on a surface. Air pressure is at the strongest at the earths surface because more air is above you. So, altitude (the distance from sea level) increses, air pressure decreses. think of air pressure as a human pyrimid,the people at the bottom of the pyramid can feel all the weight and pressure of the people on top. air pressure works in a similar way.
How does temperature put wind in motion?
Temperature rising and falling increases or reduces air (density) pressure. Air will move from a high pressure to a low pressure system to balance it out. That movement is wind.
How much air pressure do you put in the front fork on an 1985 Honda 200x?
Those are actually to let air pressure out that builds up while riding. If you add air to them they will get really stiff.
How do you turn off the low tire pressure on the dashboard?
Put air in the tire!
How can people withstand pressure in submarine?
A submarine is kept at, or close to, surface air pressure.
