Question

How nitrogen developed on earth??

Answer 1

Nitrogen may have arrived on Earth in ancient meteorites after the planet had already formed, according to a new study.

Reported in the journal Nature Geoscience, the research illustrates how meteorites - often portrayed as portents of doom and destruction - may actually have been key to the development of life on Earth.

Answer 2

hey user here is ur ans is.......

All of the nitrogen on earth was formed billions of years ago in the cores of giant stars,along with other elements such as carbon,oxygen,silicon,iron,etc.these stars later exploded and scattered their contents across the cosmos,and still later a cloud of this star debris collapsed to form earth along with the rest of the solar system.
Much of the nitrogen on earth exists in the form of dinitrogen (N2) in the atmosphere.the rest exits in the form of nitrogen - containing compounds in the oceans, in the soil, in fresh water, and in the bodies of plants, animals, and bacteria. Each of these reservoirs is constantly exchanging nitrogen with the others, in what is called the Nitrogen cycle.

hope it's help!!!
