Nitrogen (which makes up about 78% of the atmosphere) and Oxygen (about 21%)
Nitrogen and oxygen make up the majority of the atmosphere, but there are other gases as well, such as carbon dioxide, ozone, and helium.
1. Nitrogen - cca. 78 % 2. Oxygen - cca. 21 % 3. Argon - cca. 1 %
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 main gases in Earth's atmosphere are nitrogen, followed by oxygen.

Hydrogen and helium are the two main gases in the Universe.
There are not two gases in the layer but one. Ozone is the only gas present in the ozone layer.
