Why the Troposphere Has Higher Pressure Than the Mesosphere

The troposphere has higher pressure than the mesosphere because it is the layer of our atmosphere that is closest to the earth. It's the lowest, and there are other layers over the troposphere. Gravity is pushing down on our atmosphere, and it's squishing all the layers down on eachother. So, just like the lower you go down in a swimming pool the more pressure is over you- the lower you are in the atmosphere more pressure is over you. The troposphere has the stratosphere, the mesosphere, and the thermosphere on top of it, being pushed down by gravity. So, compared to the mesosphere that only has the thermosphere on top of it, the troposphere has higher pressure.
