- is the innermost layer

- has the highest air pressure

Explanation:

The troposphere is the lowest, or rather the innermost layer of the atmosphere. This is the layer that is bordering the lithosphere. The troposphere has by far the highest amount of gasses in it, thus making it the densest layer with the highest air pressure. Another characteristic of the troposphere is that all of the weather conditions are happening in it, thus all of the clouds, winds, precipitation we see and experience are formed in this layer.
