Nitrogen — 78 percent. Oxygen — 21 percent. Argon — 0.93 percent. Carbon dioxide — 0.04 percent.
36773
By far the predominant gas is carbon dioxide, making up 95.9 percent of the atmosphere's volume. The next four most abundant gases are argon, nitrogen, oxygen and carbon monoxide.
947060
According to NASA, the gases in Earth's atmosphere include: Nitrogen — 78 percent. Oxygen — 21 percent.
445270
By far, the most abundant gas in the Earth's atmosphere is nitrogen, which accounts for about 78% of the mass of dry air. Oxygen is the next most abundant gas, present at levels of 20 to 21%. Although humid air seems like it contains a lot of water, the maximum amount of water vapor that air can hold is only about 4%.

According to NASA, the gases in Earth's atmosphere include: Nitrogen — 78 percent. ... Carbon dioxide — 0.04 percent. Trace amounts of neon, helium, methane, krypton and hydrogen, as well as water vapor.
1372743
We live at the bottom of an invisible ocean called the atmosphere, a layer of gases surrounding our planet. Nitrogen and oxygen account for 99 percent of the gases in dry air, with argon, carbon dioxide, helium, neon, and other gases making up minute portions. Water vapor and dust are also part of Earth's atmosphere.

So what is air, exactly? It's a mixture of different gases. The air in Earth's atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen. Air also has small amounts of lots of other gases, too, such as carbon dioxide, neon, and hydrogen.
1154024
And depending on the composition of the planet, whether it is a terrestrial or a gas/ice giant, the gases that make up its atmosphere range from either the hydrogen and helium to more complex elements like oxygen, carbon dioxide, ammonia and methane.

Key Takeaways: Gases in Earth's Atmosphere The most abundant gas in the Earth's atmosphere is nitrogen. The second most abundant gas is oxygen.
695892
The Earth's atmosphere primarily composed of nitrogen and oxygen. Minor gases include and carbon dioxide, ozone, argon, and helium. Mars' atmosphere is a thin layer composed mainly of carbon dioxide. Nitrogen, argon, and small traces of oxygen and water vapor are also present.
1118469
The noble gases make up about 1% of the earth's atmosphere in which their major component is argon. Smaller concentrations are occluded in igneous rocks, but the atmosphere is the principal commercial source of neon, argon, krypton, and xenon, which are obtained as by-products of the liquefaction and separation of air.
