The average air pressure in the exosphere is extremely low, near to a vacuum, typically less than 0.1 Pascal. At this altitude, the few particles present are very spread out, and there is an almost complete absence of molecules.
The air mass of the thermosphere about 15 cm. of air per inch!

Which layer in the atmosphere has the most air pressure?
The layer in the atmosphere that has the most air pressure is the troposphere, which is the lowest layer where most weather phenomena occur. As you go higher in the atmosphere, the air pressure decreases.
Which layer of the atmosphere has the least amount of air pressure?
The layer of the atmosphere with the least amount of air pressure is the exosphere, which is the outermost layer of Earth's atmosphere. It is composed of very thin air molecules spread far apart, resulting in extremely low air pressure.
Where is air pressure the least?
Air pressure is typically the least at high altitudes, such as at the peak of a mountain or in the upper atmosphere. This is because there is less air above exerting pressure downwards.
Where is air pressure least?
Air pressure is least at high altitudes, such as on top of mountains or in the upper atmosphere. As altitude increases, there are fewer air molecules above, leading to lower air pressure.
Where is air pressure the greatest in the atmosphere?
Air pressure is the amount of force exerted on an object by the atmosphere. It is greatest at sea level.It is greatest in the exosphere, due to the fact that air pressure is greater as the altitude rises; the exosphere is the highest level within the atmosphere.Air pressure is greatest in the areas that are small and enclosed. This is because there is no way to escape.

Where is air pressure greater in the exosphere or in trposphere?
Troposphere.

What are the two characteristics of the thermosphere?
northern lights here between exosphere and mesosphere gravity and air pressure decrease
How does the air pressure on mars compare with earth?
earths average air pressure is 1013mb where as mars average air pressure is 7mb
What is the mass of the air in the exosphere?
The mass of air in the exosphere is very low. The exosphere is the outermost layer of Earth's atmosphere, and it contains very few air molecules. Its density is so low that the mass of air in the exosphere is considered negligible compared to the overall mass of the Earth.
What layer of the atmosphere has the lowest pressure?
the exosphere
Where is the pressure greater in the exosphere or in the troposphere?
troposphere
Where is air pressure weakest?
Air pressure is weakest at the top of the Earth's atmosphere, known as the exosphere. This is where molecules are very spread out, resulting in low pressure. Additionally, air pressure also decreases with increasing altitude, so pressure is weaker at higher elevations on Earth's surface.
