atmospheric gases
What we breathe
Atmospheric gases are the gases that make up a planet's atmosphere.
On Earth, this means primarily nitrogen and oxygen, with smaller amounts of argon, carbon dioxide, water vapor, and trace gases.
The term appears in discussions of climate science, air quality, and planetary composition: Greenhouse gases are atmospheric gases that trap heat.
