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 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.
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.
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.
Air pressure decreases with higher elevation due to the weight of the air column above pushing down. The air at lower elevations has more air above it, creating higher pressure. This is why air pressure decreases as you go higher in the atmosphere.
The layer of the atmosphere in which humans live is called the troposphere. It is the lowest layer of the atmosphere and is where weather events occur, as well as where most of Earth's air mass is concentrated.
The layer with the lowest air pressure is the exosphere, which is the outermost layer of the Earth's atmosphere. It extends from about 500 km to 10,000 km above the Earth's surface and contains very few gas particles.
The layer of the atmosphere with the lowest air pressure is the exosphere. Located above the thermosphere, the exosphere extends from about 600 kilometers (373 miles) to 10,000 kilometers (6,200 miles) above Earth's surface. In this layer, air is extremely thin, and the pressure is significantly lower than in the layers below, making it the least dense part of the atmosphere.

The troposphere is the layer of the earth's atmosphere with the highest air pressure.
The lowest and most dense layer of the Earth's atmosphere is the troposphere. It extends from the Earth's surface up to an average altitude of about 11 km (7 miles) at the poles and 17 km (11 miles) at the equator. It contains about 75% of the atmosphere's total mass.
The layer where air pressure is the greatest is the troposphere. This is the lowest layer of Earth's atmosphere, extending from the surface up to about 8 to 15 kilometers (5 to 9 miles) high, depending on the location and weather conditions. As altitude increases, air pressure decreases, making the troposphere the region with the highest density of air molecules and therefore the highest pressure.
