File:Earth's atmosphere.svg|Earth's atmosphere. Lower four layers of the atmosphere in three dimensions as seen diagonally from above the exobase. Layers drawn to scale, objects within the layers are not to scale. Aurorae shown here at the bottom of the thermosphere can actually form at any altitude in this atmospheric layer.

File:ISS-47_Islands_In_The_Sky,_Indonesia.jpg|A picture of Earth's troposphere with its different [[cloud types]] of low to [[high altitude]]s casting shadows. Sunlight is reflected off the ocean, after it was filtered into a redish light by passing through much of the troposphere at sunset. The above lying [[stratosphere]] can be seen at the [[horizon]] as a band of its characteristic glow of [[Rayleigh scattering|blue scattered]] sunlight.

File:Watching the Earth Breathe.ogv|Animation shows the buildup of tropospheric {{CO2}} in the Northern Hemisphere with a maximum around May. The maximum in the vegetation cycle follows in the late summer. Following the peak in vegetation, the drawdown of atmospheric {{CO2}} due to photosynthesis is apparent, particularly over the [[boreal forests]].
