What is the History of the Earth's Atmosphere?

The evolution of the earth (s atmosphere) refers to the air shell that surrounds the earth is called the earth's atmosphere, which is what people call air. The current atmosphere is formed by a series of complex changes in the primitive atmosphere. The primitive atmosphere appeared about 4.6 billion years ago, about three orders of magnitude earlier than humans (mankind appeared millions of years ago), and about six orders of magnitude earlier than the time when humans first appeared in writing (text Appeared thousands of years ago).

Earth atmosphere evolution

Humans cannot obtain samples of the atmosphere at various stages, and have to rely on data from stratigraphic traces and atmospheric data on the planets of the solar system (see

Formation of nitrogen and argon:

Just like the carbon dioxide in the atmosphere, a part of it was originally from the secondary atmosphere.

Impact of human activities on atmospheric composition:

Since the formation of the earth to the modern era, it has experienced three stages: the primitive atmosphere, the secondary atmosphere, and the present atmosphere. But now the composition of the atmosphere will not change, and it will change with the changes in natural conditions and the impact of human activities in the future. For example, nitrogen in nature is approximately balanced for a certain period of time. However, the mass reproduction of humans and animals has increased the amount of free nitrogen in the atmosphere into fixed nitrogen. According to statistics, from 1950 to 1968, in order to produce fertilizer, the amount of nitrogen fixed each year increased about 5 times, which will inevitably affect the nitrogen content in the atmosphere. Atmospheric oxygen and carbon dioxide are also affected by human and animal reproduction and
