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.

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.

The Phanerozoic Eon is the longest division of geological time, spanning approximately the last 541 million years and continuing to the present day. It is further divided into three eras: the Paleozoic, Mesozoic, and Cenozoic eras.
Epoch
precambrian times
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.
The longest in geological time is an Eon eg. Archeozoic Eon . Edit: there is also the supereon, which is usually composed of 2-3 eons.
Eon
an era uhm NO ^ an eon . (apex)
The largest expanse of time on the geologic time scale is the eon, which is further divided into eras. Eons are the longest subdivisions of time, representing billions of years of Earth's history.
The longest subdivision in geologic time is the eon, which is further divided into eras. Eons represent the largest interval of time in the geologic time scale, such as the Phanerozoic eon which encompasses the last 541 million years.
an era uhm NO ^ an eon . (apex)
A period is smaller than an era in the geologic time scale. It is further subdivided into epochs and ages.
