In dry air, about 1% is not oxygen or nitrogen. Argon accounts for most of that. However, under extremely humid conditions, water vapor may account for up to about 4% of the atmosphere by volume.
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.
Approximately 1% of Earth's atmosphere is made up of gases other than oxygen and nitrogen, including argon, carbon dioxide, and trace amounts of gases like helium, neon, and methane.
The main gases in Earth's atmosphere are nitrogen, followed by oxygen.
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%.
75% nitrogen, 21% oxygen, 3% other gases.
The two main atmospheric gases are nitrogen and oxygen. The approximate percentage for nitrogen is 78% and oxygen's approximate percentage is 21%.
The two main atmospheric gases are nitrogen and oxygen. The approximate percentage for nitrogen is 78% and oxygen's approximate percentage is 21%.
Nitrogen and oxygen make up the largest percentage of the atmosphere.
Oxygen and nitrogen are the two most abundant gases in the atmosphere. They make up 99% of the air.
Nitrogen,Oxygen,Carbon Dioxide And The rest of the percentage is other gases
The most abundant gases are nitrogen and oxygen in the Earth atmosphere.
Nitrogen. Nitrogen makes up roughly 78% of Earth's air. The other constituents include : * 20.95% oxygen * 0.93% argon * 0.038% carbon dioxideand traces of other gases, and transported water vapor in varying amounts.
Roughly 78% nitrogen, 21% oxygen and 1% argon
