As we know, the study of planet earth is certainly complex because the entity in observation It is precisely so, inasmuch as the experts and scholars in the field use various tools to deepen their studies and then the knowledge that is obtained is also carefully and particularly structured so that its knowledge is more accessible and recognition.
And it is on this path that the concept of eons what concerns us in this review. Because eons are each period in which geologists have determined to divide the history of our planet earth. More precisely, there are three.
That is, the aeon is the maximum division of time that exists and is used in the scale geological temporal, which is the only framework with which we humans have to be able to represent in an orderly and chronological way the various events that had space in the history of the planet.
Now, it is worth indicating, since it is very important when it comes to understanding why an eon begins or ends, that this The starting or ending situation will be determined by those substantial and important changes with regard to the
evolution of living beings.It is also important that we clarify that an eon does not imply a specific number of years to be defined as such, there was never an agreement to establish it, the idea of its use is to indicate that the time involved in an eon is important.
To better understand this stratification what does the geology To know the planet we inhabit, we must indicate that the division that precedes that of aeon is that of the supereon, while those that continue them are the famous eras (Cenozoic, Paleozoic, Mesozoic, between others).
And finally we must say that those three eons are: Phanerozoic, Proterozoic and Archaic. The first is characterized by the fact that the organisms macroscopic such as plants, animals, mushrooms, among others. In the following one of the great events were the first glaciations and in the last eon they produce the great movements of tectonic plates that give way to the planetary structure of today day.
