The archean is one of the four principal eons of earth history. When the archean began, the earth’s heat flow was nearly three times as high as it is today, and it was still twice the current level at the transition from the archean to the proterozoic (2,500 ma). During the beginning of the archean eon, about 4 billion years ago, as the frequency of meteorite impacts slowed, the earth cooled, clouds formed, and the crust began to harden from the molten globe. But in the archean eon, earth finally starts to cool down from its molten state. The latter is the second formal division of precambrian time. Hadean eon, informal division of precambrian time occurring between about 4.6 billion and about 4.0 billion years ago.

During this era, oxygenic photosynthesis first evolved, releasing an abundance of oxygen, that first reacted with minerals and afterward was free to react with greenhouse gases of the atmosphere, leaving the earth’s surface free to radiate its energy to space. Records of earth's primitive atmosphere and oceans emerge in the earliest archean (eoarchean era). The latter is the second formal division of precambrian time. During the proterozoic eon, modern plate tectonics became active, and the ancient cores of the continents moved. There was no oxygen gas on earth. Oxygen was only in compounds such as water. From 4.6 to 4.0 billion years ago, the hadean eon was a violent time in earth’s geologic history. Since then earth's climate has gone through four cycles of frigid glaciers and warm tropical seas.

The precambrian encompasses the archean and proterozoic eons, which are formal geologic intervals that lasted from 4 billion to about 541 million years ago, and the hadean eon, which is an informal interval spanning from 4.6 billion to 4 billion years ago. Oxygen was only in compounds such as water. The hadean eon is characterized by earth ’s initial formation—from the accretion of dust and gases and the frequent collisions of larger planetesimals —and by the stabilization of its core and crust and the development of its atmosphere and oceans. If you were able to travel back to visit the. What happened at the end of the archean eon?
