Nitrogen. Oxygen comes in second.
Mainly hydrogen and helium - which were also the main elements in the early Universe.
The major gases of the atmosphere are mainly nitrogen and oxygen. Nitrogen takes up 78.09% of the air and oxygen takes up 20.95% of the air. The rest is made up of 0.93% argon and 0.039% carbon dioxide.
what is most of the air in the atmosphere made up of
Mercury's atmosphere is almost nonexistent but may have a very little bit of helium, sodium, and oxygen. Venus' atmosphere is made up of carbon dioxide, nitrogen. Earth's atmosphere is made up of oxygen and nitrogen, with small amounts of carbon dioxide and other gases. Mars' atmosphere is made up of carbon dioxide, nitrogen, argon, less than 1% oxygen and carbon monoxide. Jupiter's atmosphere is made up of hydrogen, helium, and methane . Saturn's atmosphere is made up of hydrogen and helium. Uranus' atmosphere is made up of hydrogen, helium, methane, and acetylene. Neptune's atmosphere is made up of hydrogen, helium and methane.
stratosphere is because it is the layer bad up of mainly gas .
Mercury's atmosphere is MAINLY made up of sodium
The Sun's atmosphere is mainly made of hydrogen on the plasma state.
The atmosphere of Jupiter is mainly made up of 89% hydrogen.
That planet is Earth.
The earth's atmosphere is primarily Nitrogen (78%) followed by Oxygen (21%)
Uranus
Mercury's atmosphere is mainly made out of sodium.
Mainly Oxygen
Assuming you mean "carbon dioxide", the atmosphere of Venus is made up mainly of carbon dioxide.
The early atmosphere of the earth was mainly CO2, where as now its mainly nitrogen (around 78%), Oxygen (around 21%) and a bit of CO2 and argon
Theoretically none. The Earth has an atmosphere comprised of mainly nitrogeon 78% and oxygen 21% and as far as we know it is the only planet.
Mainly hydrogen and helium - which were also the main elements in the early Universe.
