Why is air pressure lower at a higher elevation than at a lower elevation?

At higher elevations, there is less air pushing down from above and therefore less weight to support. The higher you go the less air there is above you to press down on you Air pressure is due to the mass of air above you that presses down upon you - even gases have mass!
The particles have to counter gravity to get higher up which requires a high velocity. The vast majority however don't have the required velocity to reach higher altitudes so there are naturally a lower density of air particles the higher up you go.

∙ 12y agoAt lower elevations, more air is pushing down because of gravity. Just as if one were to go 100 ft below a lake vs. 10 feet. There is more air, just as there was more water above you in the lake, which causes pressure to rise. This pressure, ATM, can be measured by a barometer, full of liquid Mercury. The mercury is pushed up into a tube by the atmosphere, allowing us to see exactly how much the pressure has risen or lowered. The standard for ATM is 760 torr, or millimeters of mercury in a barometer. At lower elevations, ATM could reach close to 800 torr or less. Im not sure what the highest ATM pressure recorded is but that's for another question.

Is air pressure higher at higher elevation?
Lower. There is less air pressure pushing down on you, than say, a deep sea diver
When the water level is higher inside than outside the flask is the gas pressure in the flask higher or lower or the same as the atmospheric pressure?
The gas pressure in the flask is lower than the atmospheric pressure when the water level is higher inside than outside the flask.
Is a sunny day higher or lower pressure than a rainy day?
higher
Why do artesian aquifers contain water under pressure?
Because the area of recharge is usually at a higher elevation than the rest of an aquifer....
Does higher pressure make larger tornado's?
No. Stronger tornadoes (which are usually larger) have lower pressure than weak ones.
Is air pressure higher at higher elevation?
Lower. There is less air pressure pushing down on you, than say, a deep sea diver
Why does water have a different boiling point at elevation than at sea level?
At a higher elevation there is less air pressure. In all liquids, a lower pressure means a lower boiling point.
Is the elevation of eastern Africa higher or lower than western Africa?
Lower in elevation.
Does the sea have more air pressure than the mountain?
The higher the elevation the lower the air pressure. Sea level is considered the standard for air pressure measurement.
Why does water boils at lower temperatures than in a valley?
Water boils at lower temperatures at higher altitudes because the atmospheric pressure is lower. In a valley, the air pressure is greater, which allows water to reach a higher temperature before boiling. At higher altitudes, where the air pressure is lower, the boiling point of water decreases.
Are the Rockies higher than the Alps?
The Rockies have a lower elevation but higher latitude than the alps. So the alps are higher than the Rockies.
Is the is the elevation of eastern Africa higher or lower than western Africa?
tdk
Why is the air pressure lower at the Equator than at the North and South poles?
because sinse the land had a lower elevation, the air is not so heavy,. Does that make sense? Okay, It you were on a mountain the air pressure would be higher than if you were on the beach.
Why is a bag puffed up when you are 3000 meters high?
It was packaged at a lower elevation where the air pressure is higher. As you move to a higher elevation the external air pressure decreases, but the air pressure in the bag stays the same. So the bag "blows up" like a balloon because the pressure inside it much greater than the pressure outside. Same thing happens in your ears.
Why is it colder in highlands than lowlands?
It is colder in the highlands than the lowlands because the higher the elevation, the colder it becomes, and the lower the elevation, the hotter.
Why is the boiling point of water lower in Shimla than in Delhi?
I think that Shimla is at higher elevation than Delhi is. If that is the case, than it is because the barometric pressure goes down at higher elevations.See the Related Questions link to the left of this answer for more about how the boiling point of water is affected by the air pressure.
Why would a place of lower elevation got struck by lightning more than a place of higher elevation?
If it has more trees, they will get struck
