photosynthesis
When plants and animals evolved, this made changes in the atmosphere on Earth
photosynthesis
Cyanobacteria changed the young Earth's atmosphere by producing oxygen as a byproduct of photosynthesis. This oxygenation of the atmosphere led to the Great Oxidation Event, which helped shape Earth's atmosphere into one more conducive to supporting complex life forms.
The atmosphere has changed over time because of the use of chlorofluorocarbons (CFC's) as well as bacterial oxidation changing NH3 into N2 and photosynthesis which made O2 more abundant than CO2.
The most upper layer of the atmosphere is the Exosphere. novanet> mesophere
