The Earth's atmosphere is made up almost entirely of two gasses, oxygen & nitrogen. It's 21% oxygen and 78% nitrogen. So, these two make up 99%. The remaining 1% is a collection of other gasses.
These gases are nitrogen, oxygen and argon.
The Earth's atmosphere is composed of primarily nitrogen (about 78%) and oxygen (about 21%). Other gases such as argon, carbon dioxide, and trace amounts of other gases make up the remaining composition. Water vapor is also present in variable amounts.
I needed this for Science so when I finally got it I wanted to help other people. They are oxygen, nitrogen, carbon dioxide, and aragon. Thank you, thank you.
Oxygen and nitrogen are the two most abundant gases in the atmosphere. They make up 99% of the air.
We know that nitrogen (at about 78%) and oxygen(at about 20 %) are the most abundant gases in the atmosphere. By inspection, it's obvious that there is only a couple of percent for all the other gases combined.

They dont they just make the earth hotter
Nitrogen and Oxygen.
Earth's atmosphere makes up a blanket or an envelope around it, which is a mixture of many gases.
Nitrogen makes up the majority of Earth's atmosphere, with about 78%. Oxygen is the second most abundant gas, making up about 21% of the atmosphere. Other gases like argon, carbon dioxide, and trace gases make up the remaining composition.
78% nitrogen, 21% oxygen, 1% carbon dioxide and other minute gases
Nitrogen and Oxygen make up nearly 99% of the dry atmosphere.
no one knows
Nitrogen and oxygen make up the majority of the atmosphere, but there are other gases as well, such as carbon dioxide, ozone, and helium.
Hydrogen and helium make up 99 percent of Jupiter's atmosphere. These two gases are the most abundant elements in the planet's composition.
