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!

RafaNo, the early Earth's atmosphere was primarily composed of carbon dioxide, water vapor, and nitrogen. It was only through processes like photosynthesis that oxygen levels began to increase, eventually leading to the predominantly nitrogen-oxygen mix we have in today's atmosphere.

What is the mixture of mostly nitrogen and oxygen?
Air
Why does the nitrogen level in the atmosphere is higher than the oxygen level?
Nitrogen is more abundant in the atmosphere than oxygen because nitrogen is about 78% of the atmosphere while oxygen is about 21%. This is due to the way the atmosphere was formed and the balance of gases that resulted from geological and biological processes over time.
What gas is more abundant nitrogen or oxygen?
Nitrogen is more abundant in the Earth's atmosphere than oxygen. Nitrogen makes up about 78% of the atmosphere, while oxygen comprises about 21%.
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.
