Ignoring the variations in moving air masses, atmospheric pressure decreases steadily with altitude. A higher altitude will always have a lower air pressure, becoming virtually zero (less than 1 kPa) at around 33 kilometers of altitude, or 108,000 feet above MSL. There are still enough molecules in the thermosphere to cause atmospheric drag on satellites in Low Earth Orbit, up to about 500 km (310 miles).

Why one of the windows in the Flying At High Altitudes Breaks?
as their is high pressure inside and low pressure outside and air moves
What is the lowest air pressure ever recorded in a tornado?
The lowest known pressure recorded in a tornado was 688 millibars in a tornado in Tulia, Texas on April 21, 2007.
Why jet engines are flown on high altitudes?
Reasons of efficiency. not the least of which is that the pressure generated in the combustion chamber has to fight less "back pressure" (think of it as pressure resistance) at high altitude because the air-pressure is less.
What happens to density at higher altitudes?
The density of air decreases at higher altitudes.
Why soft underinflated football at sea level much firmer when it is taken to a high elevation in the mountains?
The air inside the semi-deflated football is able to expand due to the lessening of air pressure in higher altitudes.
Which altitudes would have the lowest air pressure and why?
The highest altitudes have the lowest air pressure. Air pressure increases as altitude decreases. Above sea level is lower pressure; below sea level is higher pressure.
What does air pressure do as altitudes?
Air pressure increases as altitude decreases.
Is air pressure greater at high altitudes or low altitudes?
It is greater at a lower altitude.
Why does air pressure increase at lower altitudes?
The air molecules have mass. When a lot of molecues are piled up,one on top the other, the pressure increases because of that.So air pressure increases at lower altitudes.
What time of day is air pressure the lowest?
The density of air is lowest in the summer, because warmer air is less dense. (the molecules are in greater motion, and are forced farther apart)
Is air pressure the same at high altitudes?
No, it is not. The pressure decreases as the altitude increases.
Why the density decrees at higher altitudes?
the density decreases because their is more air pressure in lower altitudes and as you go up their is less air pressure making it hard to breath
When the air pressure in the lungs is greater than the air pressure outside the body you?
at higher altitudes the pressure of air is greater in our lungs as compare to the air pressure outside the body
Why do recipes change at higher altitudes?
The air pressure gets lower!
Why air is not drawn upward as the pressure at higher altitudes is greater than that in lower altitudes?
When I point out the fallacies in the question, it will be answered.-- The pressure at higher altitudes is less than the pressure at lower ones.-- The pressure acts downwardanyway.Just keep in mind that the whole phenomenon of air pressure is the resultof the weight of air, meaning the force of gravity attracting air toward thecenter of the Earth. Notice how all fear, doubt, and confusion have vanishedas if by magic.
What is a sentence for the word altitudes?
Cloud structures vary at different altitudes due to different levels of air pressure. There are several scientifically recognized altitudes of atmosphere.
Are parachutes faster at high altitudes or low altitudes?
it is faster at a higher altitude because there are less air pressure when you're away from the Earth. There are more air pressure as you come to Earth so it becomes slower.
