What is Archaean Eon?

Archaean Eon is the second geological Eon in the history of the Earth, starting at the end of the Hadean Eon 3800 million years ago (MyA) and extending to the beginning of the Proterozoic EON 2500 MyA. Unlike newer sciences, when life was abundant, the arc is defined by any limits rather than the presence or absence of certain fossils. It would be safe to say that Archaean Eon was very long since it was reflected in its name, which means old.

The origin of life has ever become an early Archean, about 3.5 billion years ago. This is confirmed by fossil evidence in the form of trees, the remains of simple microorganisms that created strong layers of biotic mud during died. The arc begins shortly after it has pulled a series of events called late heavy bombing, during which pieces of solar residues that have not yet formed on the planets got into gravity slipped, which is the Earth. Some biologists believe that thje bombing has been eased by the presence of a massive planet Jupiter that would sucked some of the bestLarger asteroids than they could affect our fragile planet.

In the arc, the heat flow of the country was about three times higher than no free oxygen, the atmosphere consisted mainly of carbon dioxide. Oxygen was poisonous to most microorganisms existing at that time, in fact. Instead of rust, the surface of the free iron was deposited. There were no stable continents, but rather as a result of geological activity and comet effects, they have constantly changed.

Some of the oldest rocks in the world go to Archaean or even before in Hadean. According to geologists, only 5-40% of the current continental cortex were formed during Archaean. The volcanic activity would be much greater than today, and many of the first procontinents were probably made up of huge volcanic eruptions. Due to the large amount of carbon dioxide in the atmosphere would be more acidic than today and hostile to all, except the most extremeFilm of contemporary organisms.
