What would earths atmosphere likely consist mostly of without the presence of life?
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.
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 was earth's first atmosphere was mostly a mixture of?
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.
What is earth's atmosphere mostly made out of?
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%.
What is a mixture of mostly invisible gases that surrounds earth?
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.
What is air consist mostly of oxygen?
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.
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 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 two things does the atmosphere of earth consist mostly of?
Air and cloud vaper

What is the mixture of gases in the atmosphere called?
The mixture of gases in the atmosphere is called air. It is composed mostly of nitrogen (about 78%) and oxygen (about 21%), with trace amounts of other gases such as carbon dioxide, argon, and water vapor.

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.
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.
