The troposphere. The lower you go, the higher the air pressure.
The average air pressure at sea level is 1013 mbar, or 101.3 kPa.
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.
The troposphere is the layer of the atmosphere closest to the Earth's surface and contains around 75% of the total mass of the atmosphere. This layer is where most weather phenomena occur and where we find the air we breathe.
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.
exosphere Which is the uppermost layer of the atmosphere.
The air pressure in the stratosphere is low. This layer of the atmosphere is located above the troposphere where most of Earth's weather occurs, so it has less air concentration and lower pressure as you move higher in altitude.

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.
The troposphere is the layer of the atmosphere that contains the majority of Earth's air (about 75-80%). This is where most weather phenomena occur and where humans live and airplanes fly.
