• water

• nitrogen

This greenhouse gas cellular respiration and absorbed by plants.

• ozone

• carbon dioxide

• nitrogen

• argon

Commercial planes typically fly in this atmospheric layer.

• troposphere

• stratosphere

• mesosphere

• thermosphere

• exosphere

This atmospheric layer is too high for airplanes and too low for satellites, partially because of how cold it is.
