Oxygen and Nitrogen
Nitrogen and oxygen.
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.
Nitrogen and Oxygen
The 3 types of gases in Earth's atmosphere are argon, oxygen and nitrogen.
Nitrogen is the main gas in earth's atmosphere, composing 78% of it by volume while oxygen is 21%.found at answers.com
Nitrogen (78%) and Oxygen (21%) are the two most abundant gasses in Earth's atmosphere.
Nitrogen (which makes up about 78% of the atmosphere) and Oxygen (about 21%)
Various gases are found in stratosphere. The main however is ozone.

Nitrogen, Oxygen, Carbon Dioxide and Neon are the four main gases in order of percentage.
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.
This is the approximate composition of the atmosphere today:78% Nitrogen21% Oxygen0.004% CO2The rest consists of Noble Gases, as well as traces of other various gases, like Ammonia and Carbon Monoxide.
