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.
If Earth did not have any life, its atmosphere would likely consist mostly of nitrogen, similar to the atmosphere of Mars or Venus. Volcanic activity would have likely contributed to the release of gases like carbon dioxide and water vapor. Sunlight and cosmic rays might also have influenced the composition of the atmosphere over time.
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.
Earth's first atmosphere was mostly a mixture of gases such as hydrogen, helium, methane, and ammonia. Over time, volcanic activity released gases like carbon dioxide and water vapor, which changed the composition of the atmosphere.
Earth's atmosphere is mostly made up of nitrogen (about 78%) and oxygen (about 21%). Other gases like argon, carbon dioxide, and trace amounts of other gases make up the remaining 1%.
The mixture of mostly invisible gases that surrounds Earth is known as the atmosphere. It is composed mainly of nitrogen (about 78%) and oxygen (about 21%), with trace amounts of other gases such as argon, carbon dioxide, and water vapor.
Air consists mostly of nitrogen, with oxygen making up approximately 21% of the atmosphere. Other gases such as argon, carbon dioxide, and trace amounts of other gases are also present in the air.
The planet Saturn does have an atmosphere, and indeed, it consists mostly of atmosphere. The main chemical constituents of the atmosphere of Saturn are methane, ammonia, and hydrogen.
They are very large, and consist of mostly gases.
If Earth did not have any life, its atmosphere would likely consist mostly of nitrogen, similar to the atmosphere of Mars or Venus.

Mostly Nitrogen, and then Oxygen.

The two gases that are most common in interstellar clouds,consist mostly of gas,especially hydrogen and helium.
Yes, Jupiter is primarily composed of gases, with hydrogen and helium making up the majority of its atmosphere. It lacks a solid surface, and deeper layers may consist of liquid metallic hydrogen and other exotic materials. This gas giant's thick atmosphere features clouds of ammonia and water vapor, contributing to its distinctive bands and storms.
