The geologic time scale is a system used by geologists to organize Earth's history into distinct time periods based on major geological events and changes. Its principal subdivisions are eons (such as the Precambrian and Phanerozoic), which are further divided into eras, periods, and epochs. These subdivisions help scientists understand and study the vast expanse of Earth's history in a structured manner.
The shortest subdivisions of the geologic time scale are epochs, which are part of periods. Each epoch represents a significant span of geological time characterized by specific events in Earth's history, such as climate changes or major biological developments. Below epochs are ages, which are even shorter time intervals that detail more precise geological or paleontological events.
Eras in the geologic time scale are divided into periods. Each period represents significant intervals of geological time characterized by distinct geological and biological events. Further subdivisions of periods are known as epochs, and these can be further divided into ages.
Cenozoic is not a major period of the geologic time scale. The scale is broken down into eras. Cenozoic, Mesozoic and Paleozoic are all part of the Phanerozic era.
Phanerozoic is the eon which geologic time scale means visable life.
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 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 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.
Eras are subdivisions of larger units of geologic time called eons.
The shortest subdivisions of the geologic time scale are epochs, which are part of periods. Each epoch represents a significant span of geological time characterized by specific events in Earth's history, such as climate changes or major biological developments. Below epochs are ages, which are even shorter time intervals that detail more precise geological or paleontological events.

The geologic time scale.
The Geologic Time Scale is divided up by four major intervals. In order from Largest to smallest: Eons are the largest time frame covering hundreds of millions of years. Eons are divided into smaller time intervals known as Eras. Eras are subdivided into Periods. Periods are broken into finer subdivisions known as Epochs.
Geologic Time. It's called the Geologic Time Scale.
Cenozoic is not a major period of the geologic time scale. The scale is broken down into eras. Cenozoic, Mesozoic and Paleozoic are all part of the Phanerozic era.
Phanerozoic is the eon which geologic time scale means visable life.
