No, the Nitrogen in the air has probably always been there (because nitrogen is rather inert), but originally Earths atmosphere was reducing (it had no free Oxygen) and probably contained large amounts of CO2 and hydrocarbons. The present atmosphere on Earth is the product of biological processes which have slowly introduced free Oxygen into the Oceans and then the atmosphere - life made Earth habitable for life!
What else can I help you with?
What is the mixture of mostly nitrogen and oxygen?
Air
Why does the nitrogen level in the atmosphere is higher than the oxygen level?
Because due to the over pollution and cutting down the tree's level of Oxygen is decreasing .The level of Nitrogen always remains constant in the atmosphere . The level of Nitrogen doesn't' depend on the level of the Oxygen level.
What gas is more abundant nitrogen or oxygen?
In the atmosphere, Nitrogen is about four times as common as is Oxygen.
Does the atmosphere have more nitrogen or oxygen in it?
The atmosphere contains more nitrogen than oxygen. Approximately 78% of the atmosphere is nitrogen, while oxygen makes up about 21%. The remaining 1% consists of other gases like argon, carbon dioxide, and trace gases.
What is more abundant in the atmosphere oxygen or Nitrogen?
Nitrogen is more abundant in Earth's atmosphere, making up about 78% of the air. Oxygen makes up about 21% of the atmosphere.
Is the atmosphere mostly oxygen?
No. About 79% is nitrogen.
Is earths atmosphere mostly oxygen and hydrogen?
No, Earth's atmosphere is mostly composed of nitrogen (about 78%) and oxygen (about 21%). Hydrogen makes up a very small fraction of Earth's atmosphere, less than 0.1%.
What two gases are in the atmosphere on earth?
Mostly Nitrogen, and then Oxygen.
What best describes the atmosphere?
mostly nitrogen with 21% oxygen
What describes the earths atmosphere?
mostly nitrogen with 21% oxygen
Is the Earth's atmosphere an element?
No. Earth's atmosphere is a mixture, mostly comprised of nitrogen and oxygen.
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 two elements is earth's atmosphere mostly made up of?
The atmosphere is the mixture of gas molecules and other materials surrounding the earth. It is made mostly of the gases nitrogen (78%), and oxygen (21%).
What is the mixture of mostly nitrogen and oxygen?
Air
Which planet's atmosphere is mostly nitrogen and oxygen?
Earth's atmosphere is mostly made up of nitrogen and oxygen; but the planet itself is more than just its atmosphere - overall Earth, like other terrestrial planets, is mostly made from rock (silicates) with a nickel-iron core. (By comparison, overall the outer gas planets are mostly made from hydrogen and helium.) By relative abundance, oxygen is also the most common element in the Earth's crust.
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.
Is it true that earth's atmosphere is composed of liquid oxygen?
The atmosphere of the Earth is a gas, not a liquid, and although it does contain oxygen, that is just one part of the atmosphere, which is mostly nitrogen.
