Which layer of the earth's atmosphere has the highest air pressure?

Answer:
The troposphere is the layer of the earth's atmosphere with the highest air pressure. This is because the troposphere is the layer closest to the Earth's surface. As a result, the air is quite dense in the troposphere. As pressure is directly proportional to density, it means that the atmospheric pressure would be greatest in the troposphere.
