Air Pollution

Clean air is made up

Clean air is made up of 78% nitrogen, 21% oxygen, 0.035% carbon dioxide, and trace amounts of other gases like argon, methane, and ozone. Water vapor

Carbon moves between the atmosphere

Carbon moves between the atmosphere, living organisms, and the earth through photosynthesis (plants absorb CO₂), respiration (organisms release CO₂),

Nitrogen gas (N₂) is converted into

Nitrogen gas (N₂) is converted into usable forms like nitrates by nitrogen-fixing bacteria. Plants use these to make proteins, which pass through food

Greenhouse gases like CO₂

Greenhouse gases like CO₂, CH₄, and CFCs trap heat in the atmosphere by absorbing and re-radiating infrared radiation. This leads to a rise in Earth's

CFCs from refrigerants and aerosols rise

CFCs from refrigerants and aerosols rise to the stratosphere, where UV radiation breaks them down, releasing chlorine atoms. Chlorine destroys ozone (
