Atmospheric gas

From GAWDAwiki

Atmospheric gases are found in the Earth’s atmosphere and make up our air. Nitrogen (N₂) and oxygen (O₂) are most prevalent, making up 78% and 21% of the earth’s atmosphere, respectively. The remaining 1% is composed of trace gases such as argon (Ar) and hydrogen (H₂).

The air in Earth's atmosphere has some variable components to it as well. These variable components include water vapor, dust particles, and ozone. Although these are found in small amounts, they can have significant effects on weather and climate.^[1]
