Nitrogen
Nitrogen is more abundant in Earth's atmosphere, making up about 78% of the air. Oxygen makes up about 21% of the atmosphere.
In the atmosphere, Nitrogen is about four times as common as is Oxygen.
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.
Because Nitrogen makes plants grow and they provide a continuous supply of oxygen!
There is: Nitrogen (N2): 78.09% Oxygen (O2): 20.95% in the atmosphere There is ~3.73 times more oxygen than nitrogen in the air and is in a ratio (oxygen to nitrogen) of 39:10 (rounded).
Nitrogen makes up about 78% of Earth's atmosphere, while oxygen makes up about 21%. Nitrogen is needed for vital biological processes such as building proteins and DNA. It is also crucial for the growth of plants and helps maintain the balance of gases in our atmosphere.
The atmosphere of Earth today is not the atmosphere that the planet started out with, the atmosphere has been produced by the biosphere of the planet. Originally the atmosphere was made of hydrocarbons, Carbon Dioxide and Nitrogen. Living things (using photosynthesis) have changed this by using the Carbon Dioxide to make sugars and releasing Oxygen as a waste product. The free Oxygen then got into chemical processes with minerals in the Oceans to make Iron ores and slowly the Ocean and atmosphere changed to include free Oxygen. Nitrogen is very inert and while it is slightly involved in life processes its proportion was unchanged by life. Therefore the composition of the atmosphere is a changing dynamic balance resulting from the nitrogen, and carbon cycles of the planet.
Nitrogen is more abundant; our atmosphere is 78% Nitrogen.
nitrogen makes up most of our atmosphere so i should hope it's not bad to breath it. it's purpose is to dilute the oxygen in our atmosphere. things would be more flammable if the nitrogen wasn't there
Nitrogen makes up about 78% of Earth's atmosphere compared to about 21% oxygen. This difference is due to the way these gases were trapped during Earth's formation and the chemical reactions that have taken place over billions of years. Nitrogen is less reactive than oxygen, so it has remained more abundant in our atmosphere.
no nitrogen makes up more then half of all the air we breath.
There is much more nitrogen in earth's atmosphere than carbon dioxide. Nitrogen forms about 79%, while carbon dioxide makes up about 0.04%.
