Oxygen and Nitrogen
The main gases in Earth's atmosphere are nitrogen, followed by oxygen.
The Earth's atmosphere is composed of roughly 78% nitrogen and 20% oxygen, the remaining 2% is a mix of other gasses.
The two main gases found in the troposphere are nitrogen (about 78%) and oxygen (about 21%). These gases make up the majority of the Earth's atmosphere and are essential for supporting life.

The two main gases are Nitrogen (N2) and Oxygen (O2), which comprise around 78% and 21% of the atmosphere by volume respectively. The remaining 1% is mostly Argon (Ar), followed by Carbon Dioxide (CO2) as well as several other gases present in trace amounts. All of these figures are for dry air, however water vapour (H2O) is also present in air at levels of up to 4%, but this is highly variable depending on localised conditions, and it makes up a lower percentage of the atmosphere as a whole.
The two main components of Earth's atmosphere are nitrogen (about 78%) and oxygen (about 21%). Together, they make up the majority of the gases present in the atmosphere.

The three main gases in Earth's atmosphere are nitrogen, oxygen, and argon. Nitrogen makes up about 78% of the atmosphere, oxygen about 21%, and argon about 0.93%.
Nitrogen (78%) and Oxygen (21%) are the two most abundant gasses in Earth's atmosphere.
