The two most common gases in Earth's atmosphere are nitrogen (N) and oxygen (O2).
Nitrogen is roughly 78% and oxygen is roughly 21%.
The two most common gases in Earth's atmosphere are nitrogen (approximately 78%) and oxygen (approximately 21%).
The two most common gases in Earth's atmosphere are nitrogen, which makes up about 78%, and oxygen, which makes up about 21%.
The three most common gases in Earth's atmosphere are nitrogen (N2), oxygen (O2), and argon (Ar). Nitrogen makes up about 78% of the atmosphere, oxygen comprises about 21%, and argon is present at about 0.93%.
The two most abundant gases on Earth are nitrogen and oxygen.
The 8 most common gases in Earth's atmosphere are nitrogen (N2), oxygen (O2), argon (Ar), carbon dioxide (CO2), neon (Ne), helium (He), methane (CH4), and krypton (Kr). These gases make up the bulk of the atmosphere and play important roles in regulating Earth's climate and supporting life.
