Evolution of the atmosphere: Nitrogen and oxygen are the major contributor gases to the current structure of the Earth’s atmosphere. There are three states of development of the present atmosphere. The erosion of the primordial atmospheric gases took place in its first stage. In the second stage, steam and water vapor was emitted from inside the Earth and contributed to the development of the atmosphere.
In the end, the structure of the atmosphere was modified by the photosynthesis process of the biosphere. The initial atmosphere in which hydrogen and helium was abundant was removed from the earth due to solar winds. This happened not only on earth but on all terrestrial planets, that is, because of the effect of the solar winds, the primordial atmosphere was either pushed away or eliminated. This was the final stage of the development of the atmosphere.
