The divisions of the geologic time scale are divided into four eras. from earliest to closer to the present is the Precambrian, Paleozoic, Mesozoic, Cenozoic. During these time periods, there were several major evolutionary events. Most commonly known are the dinosaurs and humans. Hope that helped :)
Eon is the broadest division on the geologic time scale, representing the longest time span. Eons are further divided into eras, which are then subdivided into periods, epochs, and ages.
Epoch
an era uhm NO ^ an eon . (apex)
Eon
The largest division of time on the geologic time scale is an eon. Eons are subdivided into eras, which are further divided into periods, epochs, and ages. The current eon, the Phanerozoic, began around 541 million years ago and is divided into the Paleozoic, Mesozoic, and Cenozoic eras.

Epoch
The shortest division in the geologic time scale is an Epoch. Epochs are subdivisions of a period and are typically tens of millions of years long.

A period is smaller than an era in the geologic time scale. It is further subdivided into epochs and ages.

geologic time scale. i got this answer from a final in my science class
The geologic time scale.
Geologic Time. It's called the Geologic Time Scale.
Century - A century is not a major period of the geologic time scale. The major divisions of the geologic time scale are eons, eras, periods, and epochs.
