They dont they just make the earth hotter
Earth's atmosphere makes up a blanket or an envelope around it, which is a mixture of many gases.
78% nitrogen, 21% oxygen, 1% carbon dioxide and other minute gases
Nitrogen and Oxygen make up nearly 99% of the dry atmosphere.
The most prominent gases are nitrogen (78 percent), oxygen (21 percent) and argon (nine-tenths of a percent).
Argon and trace gases like neon, helium, and methane make up less than 1 percent of Earth's atmosphere.
Nitrogen N2 78.08% Oxygen O2 20.95%
The two primary gases in the Earth's atmosphere are nitrogen and oxygen.
