what effect does altitude have on air pressure?

Answer 1

If you have a more mathematical turn of mind, ref 1 has an excellent discussion of how altitude affects pressue.

Answer 2

The higher the altitude the less gravity energy per Unit volume.That means that there are less atoms of air in a cubic meter than at sea level.So the air presure is directly proportional to The Energy contained in the atmosphere per unit volume.
Pressure at different altitudes varies exponentialy.
At 18000 feet the Oxigen content of the air is one half of the oxigen at sea level.

Answer 3

There is less pressure in Denver than in LA, because there is less atmosphere above you pushing down. So it's a bit harder to breathe and water boils quicker up there at altitude.

Answer 4

The higher the altitude the lower the air pressure.
there are less air molecules, so as we get further away from the earth approaching space the pressure gets less and less.

Answer 5

The higher the altitude, the lower the air pressure...that's why your ears "pop" when you are in a plane.

Answer 6

This is known as static pressure, it is how altimeters work, the higher you go the less pressure, I think you did not put much effort into thinking this out.

Answer 7

the higher the altitude, the higher the air pressure will be.. its like in air planes, did u notice that all commercial planes are air tight, i mean the inside of the plane is pressurized to keep the air pressure inside constant... basically like the pressure on the ground... i hope this helped u out a lot! :)

Answer 8

atmospheric pressure at sea level is appx. 9 pounds to the square inch. when you are underwater there is no longer atmospheric pressure, the increasing pressure is from the weight of the water being pulled toward the earth by gravity

Answer 9

As you go higher above the earth, the air pressure decreases.

Answer 10

the high the altitude the less the air pressure is.
