Think of the air pressure on any horizontal surface as the weight of all the air above it, all the way to the top of the atmosphere. As you increase altitude (go higher, on a mountain or in an airplane), there is steadily less atmosphere above you, and the air pressure steadily decreases with altitude.

Atmospheric pressure decreases with increasing altitude. This is because there is less air above pushing down on the air below as you move higher in the atmosphere. As a result, atmospheric pressure is highest at sea level and decreases as you move higher in elevation.

As the altitude rises, the air pressure decreases. The pressure decreases because there is less air above you. Imagine an "ocean" of air sitting on top of you all the time. That's what is responsible for the 101.3 kPa of pressure you feel. As you increase your altitude, just like if you were coming up from deep under the water, there will be less weight on top of you pushing down, thus the pressure will decrease.

The higher up you are, the less air pressure. The air thins out the higher you go, thus leaving less air in the atmosphere to push you down.

the higher the elevation the lower the air pressure

this happens because the higher the elevation the less dense the air

If you mean height above the Earth's surface, atmospheric pressure varies inversely with altitude.

The higher one's elevation, the lower the atmospheric pressure. Pressure drops away close to nothing much above 100,000 feet.

Why does the height of the column in a barometer changes as atmospheric pressure changes?

As the atmospheric pressure changes, the force pushing on the surface of the liquid changes. Therefore,the height of the liquid in the tube increases as the atmospheric pressure increases.


Why does the height of the liquid column in a barometer changes as atmospheric pressure changes?

The height of the liquid column in a barometer changes as atmospheric pressure changes because atmospheric pressure exerts force on the liquid in the barometer tube. As atmospheric pressure increases, it pushes the liquid column higher to maintain balance. Conversely, as atmospheric pressure decreases, the liquid column falls due to reduced pressure pushing up from below.


A decrease in the height of a column in a mercury barometer means that?

there is a decrease in atmospheric pressure. Atmospheric pressure is directly proportional to the height of the mercury column in a barometer. When the height decreases, it indicates that the pressure in the atmosphere is lower.


What does Mercury borometer measure?

A mercury barometer measures atmospheric pressure by determining the height of a column of mercury that is supported by atmospheric pressure in a closed tube. By observing changes in this column height, meteorologists can track changes in atmospheric pressure over time.


How do you get the percentage of atmosphere above a height given in km and then how do you get the pressure for the height in mb What is the formula?

Formulas for atmospheric pressure variation with altitude. Scroll down to related links and look at "Atmospheric pressure - Wikipedia".


Why height is always measured at sea level?

atmospheric pressure ... the diff. in the two pressure in which it will find the height from the level of sea


How is the can in the pan of water similar to the mercury barometer?

Both the can in the pan of water and the mercury barometer function based on the principle of atmospheric pressure. In both cases, changes in atmospheric pressure will cause a corresponding change in the level of water or mercury in the device. The height of the water or mercury serves as an indicator of the atmospheric pressure at that moment.


How do you get the percentage of atmosphere above a height given in km and then how do you get the pressure for the height in mb?

To find the percentage of atmosphere above a certain height in kilometers, you can use the barometric formula to calculate the pressure at that height. Then, you can simply divide the pressure at the given height by the pressure at sea level (1013.25 mb) and multiply by 100 to get the percentage of atmosphere above that height.


What doesnot cause the height of mercury column to vary?

A change in the material of the container holding the mercury does not cause the height of the mercury column to vary. The height of the mercury column is determined by the atmospheric pressure acting on the surface of the mercury in the container.


Why does atmospheric pressure increase with height?

Atmospheric pressure decreases with height due to the weight of the air above pushing down on the air below. As you move higher in the atmosphere, the air becomes less dense because there is less weight of air above it, leading to a decrease in pressure.


What can change the boiling point of water?

The boiling point of water can be affected by changes in atmospheric pressure. At higher altitudes where the atmospheric pressure is lower, the boiling point of water is lower. Conversely, at lower altitudes with higher atmospheric pressure, the boiling point of water is higher.


Why do climbers need to acclimatise?

So they get used to the height and lower atmospheric pressure.
