Probably about the same as yours, something like 78% nitrogen, 21% oxygen, almost 1% argon, 0.04% carbon dioxide, and some other trace gases. And there's some water vapor.

Why is the atmosphere made mostly of gas?
The atmosphere is made mostly of gas because gases have low molecular densities, allowing them to be easily suspended in the Earth's gravity. The gases in the atmosphere help regulate temperature and provide elements essential for life, such as oxygen.
What would earths atmosphere likely consist mostly of without the presence of life?
c water vapor
Which gases made up most of Earths early atmosphere?
mostly carbon dioxide with little or no oxygen.
What are atmosphere gases?
atmosphere gases are made of air
What effect would an increase in greenhouse gases in the atmosphere have on earths overall temperature?
Of course, greenhouse gases keep the Earth from being one large popsicle. The newest studies of the atmosphere indicate that the atmosphere is pretty stable, now. The reason is that nearly all of the greenhouse gases are water vapor mostly evaporated from the oceans.
What are the jovian planets like?
They are very large, and consist of mostly gases.
What two gases are in the atmosphere on earth?
Mostly Nitrogen, and then Oxygen.
What is the Name for planets whose atmosphere is made up of mostly gases?
atmosphere is made up of gases in all planets. But if you mean planets that are mostly atmosphere, then those are gas giants (Jupiter, Saturn, Neptune, Uranus)
What two things does the atmosphere of earth consist mostly of?
Air and cloud vaper
Do greenhouse gases thicken the air?
Greenhouse gases do not physically thicken the air. Instead, they trap heat in the Earth's atmosphere by absorbing and re-emitting infrared radiation, thus causing the warming effect known as the greenhouse effect. This leads to an overall increase in global temperatures.
Does Saturn have an atmosphere and what does it consist?
Yes, Saturn has a mostly hydrogen and helium atmosphere with traces of other gases such as methane and ammonia. The atmosphere is thick and composed of multiple layers, with strong winds and storms.
What does Uranus consist of?
Uranus consists primarily of hydrogen and helium, with a small amount of water, ammonia, and methane ice in its atmosphere. It has a rock and ice core, and a thick layer of icy mantles. Its atmosphere is mostly hydrogen and helium with some methane.
Which two gases are most common in interstellar clouds?
The two gases that are most common in interstellar clouds,consist mostly of gas,especially hydrogen and helium.
What would earths atmosphere likely consist mostly of without the presence of life?
c water vapor
Which planet has is atmosphere mostly made of nitrogen?
Neptune (NovaNet) There's something wrong here. Neptune is mainly a hydrogen atmosphere. Earth is the planet with a mainly nitrogen atmosphere, but the coldest is Neptune.
What is the earth atmosphere mostly made up of?
Earth's atmosphere is mostly made up of nitrogen, which makes up 79 percent. The atmosphere contains 20 percent oxygen and 1 percent other gases.
What is the outer atmosphere of a star called?
The outermost atmosphere of a star is called Stellar atmosphere. Within the Stellar atmosphere, the corona is the outermost part. The corona mostly consist of plasma which has a temperature above a million Kelvin.
