Why is there more air pressure in the first layer of atmosphere?
The atmosphere consists of 5 layers: the troposphere, which we live in; followed by stratosphere, mesosphere, thermosphere and exosphere. Air pressure at any of these layers is typically caused by hydrostatic pressure, defined as P = hpg, where P is the pressure, h is the height or depth of fluid, and g is the gravitational acceleration. In simple context, my physics lecturer once explained to me: the reason why we live under an atmospheric pressure of 1 bar is simply because there is a column of air above us. As we move upwards (e.g. in an airplane or on top of a mountain), the height of this column is reduced, thus the atmospheric pressure is less. Therefore, the first layer of atmosphere (or the lowest layer) will experience the highest air pressure.
In which layer of the atmosphere is air the thinnest?
The thinnest layer of the atmosphere is Exosphere.
What layer of the atmosphere do particles of air escape into space?
The layer of the atmosphere that releases particles of air into space is the exosphere.
Does Mars have Air pressure?
Yes, it has an atmosphere so it has air pressure.
An air temperature of 95DC most often exists in which layer of the atmosphere?
The air temperature of 95 degrees Celsius most often exists in the thermosphere layer of the atmosphere.
What is the lowest most dense layer in the atmosphere?
The troposphere, It has the most mass because that is where all the weather occurs.~Amanda~
What layer is the atmosphere pressure highest?
The troposphere is the layer of the earth's atmosphere with the highest air pressure.
What layer is the pressure the highest?
The troposphere is the layer of the earth's atmosphere with the highest air pressure.
Which layer of the atmosphere has the lowest air pressure?
http://www.windows.ucar.edu/tour/link=/earth/Atmosphere/layers.html Exosphere That's the outer most layer in the atmosphere. It experiences very low pressures due to the weak gravity at such astronomically high altitudes, and thus the more massive and heavy gases are in levels of the atmosphere, such as the Troposphere.
Which layer of the atmosphere has the least amount of air pressure?
The Exosphere
Where is air pressure least?
exosphere Which is the uppermost layer of the atmosphere.
Why is the air pressure in the troposphere greater with lower elevation?
ity is the lowest layer
Which of the following parts of the atmosphere contains the lowest air pressure?
The higher parts
Which layer of the atmosphere is the least dense?
Hmm... let me see. Hey, Mom, what's the answer? Oh, that's right. The Exosphere is the answer to this question.
Why does air in the troposphere move in all directions?
because it is the lowest layer in the atmosphere thanks you and have a great day!!rkjgx h;
How and why does air pressure change with alltidude in the atmosphere?
what is the name of the uppermost layer of the atmoshere
Which atmospheric layer has the greatest air pressure?
It's the troposphere because :The troposphere contains 75 per cent of the atmosphere's gas. It also holds huge amounts of dust and water vapor, and is often dense with clouds and mist. Air pressure is greatest in the troposphere, because gravity pulls the atmosphere towards the Earth, squeezing most of its weight into this lowest layer.
