Answer 2

Hi mate.


Thanks for asking this question.


Here is your answer,





$earths \: primitive \: atmosphere\%$



Our earth is formed over the

4500 million years ago. By comparison of the

today's atmosphere with the primitive

atmosphere we seen that it is very different.

At the primitive time the largest component of

the atmosphere is carbon dioxide, followed by

the nitrogen and hydrogen and the presence

of the oxygen is negligible.


This atmosphere shows that the

fullfilness of the gases produced from cooling

of the molten planets and during the volcanic

eruption. Their is no oxygen at that time, but

oxygen can be produced by the action of

ultraviolet radiation from the sun on the water

bodies.



Then, the proportion of the carbon

dioxide is reduced rapidly due to the it is

dissolved in the water.



After, the photosynthesis process

increases the amount of oxygen when the first

planet is formed.





$earths \: modern \: atmosphere \: \%$



When we see our today's

atmosphere which mainly contains nitrogen

(78.08%), oxygen (20.95%), and with

remaining gases mainly the argon (093%) and

carbon dioxide (0.03%). The decrease in the

percentage of the carbon dioxide which

directly affects on the temperature at the

earth's surface.


Today's pollution is due to the increase

in the pollutants which is also the cause of the

human interfere in the environment.





Thank you.
