Where atmospheric Nitrogen comes from?
Most our Oxygen 21% comes from photosynthesis, plant life!
Our atmosphere is 80% nitrogen, where does it come from? Thx! JS |

The solar nebular contained all the oxygen and nitrogen. the region out to about 30 AU was later swept up into planets and asteroids.

Than what maintains todays 80% Nitrogen gases in the our atmospheres! Does animal life contribute to it, like termites, cows etc... breathing out ammonia? Thx! JS |

I *think*, but don't know for sure, that it's basically too inert to get absorbed, too massive to leak into outer space. -- Brian Tung The Astronomy Corner at http://astro.isi.edu/ Unofficial C5+ Home Page at http://astro.isi.edu/c5plus/ The PleiadAtlas Home Page at http://astro.isi.edu/pleiadatlas/ My Own Personal FAQ (SAA) at http://astro.isi.edu/reference/faq.html |

It's not _that_ inert. N2 is always being removed from the atmosphere by various nitrogen fixation processes. Other processes are converting nitrates to free N2. Nitrogen, oxygen, and CO2 are at their present concentrations because they are maintained there by active processes, both biological and geological. When first discovered it was given the name _azote_, "lifeless", because the gas would not support respiration; somewhat ironically, considering its important functions in all living organisms, this term (or variations thereof) remains the usual name for the element in several European languages, including the original French. Some other languages use terms derived from their words for suffocation or choking. -- Odysseus |
