Why percentage of nitrogen in air is higher?
That's simply the way earth's atmosphere evolved. And fortunate for us - if the earths atmosphere was 100% oxygen, the planet would have burst into flames long ago! Earth's atmosphere is 79% Nitrogen.
Was the atmosphere of the earth always mostly nitrogen and oxygen?
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!
Why does oxygen occur naturally?
It is a byproduct of the life processes on Earth. Earth's early atmosphere contained no Oxygen, but Earth was slowly Terra-formed by life and obtained an Oxygen rich atmosphere.
What is the approximate percentage of oxygen in the atmosphere?
Earth's atmosphere is about 21% oxygen by volume (for dry air).
What percentage does nitrogen and oxygen make in the atmosphere?
Nitgrogen forms 80% of the Earth's atmosphere and oxygen 21%
What essentials for life are found in earths atmosphere?
The Earths atmosphere protects the earth from meteors and it tgives us oxygen
What makes up Earth's air?
Nitrogen makes up 78% of the earths atmosphere Oxygen makes up 21% of the earths atmosphere
What is the percentage of Oxygen on earth?
Earth contains 21 percent of oxygen in the atmosphere!coz earth contains only hot gases and oxygen is not a hot gas!:D
What is Earths atmosphere is made up of what?
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.
Percentage of oxygen in earths lower atmosphere?
what atmosphere is 75 km away from earth
Which gas in Earth's atmosphere suggests that there is life on Earth?
The gas in earths atmosphere that suggests that there is life on Earth is oxygen. However carbon dioxide also shows that there is life on Earth.
What planet has a nitrogen- oxygen atmosphere?
Earths atmosphere is rich in Oxygen, some 21% of the air is Oxygen. There is oxygen on other planets, but the percentage comes nowhere close to this. The percentage of Oxygen in earths atmosphere is thought to have been much higher in the past, before animals were about, but after the arrival of plants.
How much is the earth atmosphere is made up of nitrogen and oxygen?
The earths atmosphere is made up of 78% nitrogen and 21% oxygen
What is the abundant element in the earths atmosphere?
Oxygen, not quite Nitrogen makes up 78% of the earth's atmosphere.
What is the current atmosphere of Earth believed to be?
Earths atmosphere is made up mostly of oxygen and carbon dioxide.
What is the earths 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 a component of the earths atmosphere?
Significant components of the Earth's atmosphere include nitrogen, oxygen, and carbon dioxide.
