The higher the altitude, the lower the pressure becomes. One way to think of this is that the lower levels of the atmosphere, near the surface, are being pressed down by the molecules stacked above them, all of them drawn by Earth's gravity. Similarly, water in the oceans exerts a higher pressure the deeper you dive.
Also, at the higher levels of the atmosphere, it is easier for molecules of lighter gases to achieve enough velocity to fly off into space.
What else can I help you with?
What happens to atmospheric pressure as altitude increase?
This would actually be a simple answer: Pressure decreases. Simply because of the fact that as altitude increases, the less air there is on top of you, and the lower the pressure would be.
What happens to the relative humidity of air as it increases in elevation?
As air increases in elevation, its relative humidity typically decreases.
When intraalveolar pressure exceeds atmospheric pressure what happens?
If intraalveolar pressure exceeds atmospheric pressure, air will flow out of the lungs due to the pressure gradient. This process is known as exhalation or expiration. It allows the lungs to get rid of carbon dioxide and regulate the levels of gases in the body.
What happens to the temperature of the air when elevation increases in the troposphere?
As elevation increases in the troposphere, the temperature of the air generally decreases. This is due to the decrease in air pressure with increasing elevation, which leads to the expansion of air and cooling through adiabatic processes.
What happens to the pressure of the earth as depth below the surface increases?
the pressure decreases the pressure increases
What happens to atmospheric pressure as altitude increases?
As altitude increases, atmospheric pressure decreases.
In general as elevation increases from the ground up what happens to atmospheric pressure?
Pressure decreases. This is because atmospheric pressure is a measure of the weight of the atmosphere weighing down. If you are high in the atmosphere, much of the atmosphere is below you so the pressure from above will be very small.
What happens to fluid pressure as elevation increases?
it elevates unless you can control it. true
What happens to boiling point above sea level?
As you go above sea level, the atmospheric pressure decreases, and so the boiling point also decreases to below 100ºC.
What happens to atmospheric pressure as you move up away from sea level?
As altitude above seal level increases, atmospheric pressure decreases.
What happens to atmospheric pressure as altitude increase?
This would actually be a simple answer: Pressure decreases. Simply because of the fact that as altitude increases, the less air there is on top of you, and the lower the pressure would be.
What happens to the relative humidity of air as it increases in elevation?
As air increases in elevation, its relative humidity typically decreases.
When a liquid sample is taken from sea level to a higher elevation what happens to the external pressure on the liquid and the boiling point of the liquid?
atmospheric pressure is lower and the boiling point is less
When the pressure of a gas increases at constant pressure what happens?
Volume increases
What happens to air when it sink?
When a parcel of air is forced downward, atmospheric pressure increases, causing the air to become compressed and therefore the temperature is also raised.
What happens to pressure as step increases from the lithosphere to core?
Pressure increases as step increases from the lithosphere to core
When intraalveolar pressure exceeds atmospheric pressure what happens?
If intraalveolar pressure exceeds atmospheric pressure, air will flow out of the lungs due to the pressure gradient. This process is known as exhalation or expiration. It allows the lungs to get rid of carbon dioxide and regulate the levels of gases in the body.
