Why the pressure of the atmosphere decreases with increasing altitude?

Simply put, there's less of it to push down on you the higher you get. Atmospheric pressure is the pressure of all the air above you, pushing down. The higher up you get, the less atmosphere is above you to press down, so less pressure.

This is because as the air is transparent to the sunlight the air effectively heated at or near the earth's surface. Also the density of the atmosphere decreases with height.

∙ 15y agoMany answers (some better than others). Here are two explanations: The logical way of thinking is that pressure is formed because of the presence of particles. Particles have mass. Things with mass are influenced by gravity. The closer a mass is to the center of the earth (lower altitude), the more pull it receives from the earth. So this gravity pulls most of the mass close to it. Another thought: Because each particle has mass, we can substitute other things, so it's more visual. Take a tub of water, actually a pool. Where is the pressure greatest, at the bottom or top? Bottom, right? Gravity pulls the water molecules down making it denser. Besides that, there's more water, causing the pressure of the water on the bottom to be higher.

When altitude increases does air density?
The density of the atmosphere decreases with altitude.
How does the air pressure change as the altitude increases?
As altitude increases, air pressure decreases. Gravity causes the atmosphere to become heavier the closer you are to the ground. The atmosphere may seem weightless but all the air molecules add up to a tremendous amount of mass. If you think of the atmosphere like blankets, the more blankets you have piled on you the heavier they become, thus pressing down on your body more and more. This is the same in the atmosphere, where the higher the altitude, the less overlying atmosphere, the less pressure on air molecules. At higher altitudes the air molecules have more freedom to move around.
Does air pressure and temperature change with altitude?
Yes; the pressure and temperature decreases with higher altitude.
Why does density of air decrease with increase in height?
The density of air decreases with increasing altitude because air at high altitudes is under less pressure.
What general statement can be made about the relationship between air pressure and altitude?
Air pressure decreases as altitude increases.
How does air pressure change with altitude in the atmosphere?
air grows thinner so it gives less pressure on the earth's surface
Does pressure increase as you are increasing altitude?
No. Atmospheric pressure decreases as altitude increases.
Does air pressure increase with the altitude?
No, air pressure decreases with altitude. As you go farther towards earth's surface, the weight of the atmosphere presses down with increasing force.
When altitude increases does air density?
The density of the atmosphere decreases with altitude.
What happens to air pressure's rate of change as altitude increases?
The rate of change of air pressure as a function of increasing altitude decreases with increasing altitude.
How does pressure change as you increase in altitude within your atmosphere?
it decreases
Why does the air pressure change the altitude in the atmosphere?
As the amount of air above us decreases...the air pressure decreases.
Why does air cool when it rises though the atmosphere?
As air rises it decompresses, as pressure decreases with increasing altitude. All gasses cool when decompressed. This process is called adiabatic cooling.
What is the difference between altitude and air pressure?
Air pressure is the amount of pressure exerted by Earth's atmosphere in a specific place, while altitude is the vertical distance of an object or place from sea level. Air pressure decreases as altitude increases, since there is less atmosphere to exert pressure.
What effect on air pressure with altitude explain briefly?
As altitude increases, air pressure decreases. As altitude decreases, air pressure increases.
Why density of air decreases with increase in height?
The density of air decreases with increasing altitude because air at high altitudes is under less pressure.
How does altitude affect density and pressure?
Air pressure decreases as altitude increases. As air pressure decreases, so does density.
