The geological time scale is divided into:
Eons (Such as the Proterozoic and the Phanerozoic)
THEN
Eras (Such as the Mesozoic and the Cenozoic)
THEN
Periods (Such as the Cretaceous and the Quaternary)
THEN
Series, alternatively Epoch (Such as the Pleistocene and the Holocene)
THEN
Stage (Such as the Campanian and the Tarantian)
eras
The measurement of Earth's history divided into time periods is called the geological time scale. It is divided into eons, eras, periods, epochs, and ages, with each unit representing a significant change in Earth's geological and biological history.
The era that is divided into smaller units of time scale is the "Geological Era." Geological eras are major subdivisions of geological time and are further divided into periods, epochs, and ages, allowing scientists to study Earth's history in more detail. The three primary geological eras are the Paleozoic, Mesozoic, and Cenozoic, each encompassing significant events in the planet's evolutionary history.
Geological eras can be divided into periods, epochs and ages.
Geological time is typically divided into units based on types of rock layers, fossils, and major events in Earth's history. The primary units of geological time are eons, eras, periods, epochs, and ages. These divisions help scientists organize and study the Earth's long history.
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.
Geological time eras are divided into periods, which are further divided into epochs. Each era represents a significant span of time in Earth's history, characterized by distinctive geological and biological events. These divisions help scientists organize and study the vast expanse of Earth's history.

The geological time scale.
Yes, eons are divided into eras. In the geological time scale, an eon is the largest division of geological time, and it is further subdivided into eras, which are shorter time spans characterized by significant geological and biological events. For example, the Phanerozoic Eon is divided into three eras: the Paleozoic, Mesozoic, and Cenozoic. Each era encompasses different periods of Earth's history marked by distinct changes in the planet's geology and life forms.
Eras are then divided into periods. Each period represents a significant span of geological time characterized by distinct geological and biological events. Periods can be further subdivided into epochs and ages, providing a more detailed framework for understanding Earth's history.
The largest divisions of time on the geological time scale are eons, which are the longest units of time and are further divided into eras. The current eon, the Phanerozoic Eon, is divided into three eras: Paleozoic, Mesozoic, and Cenozoic. Each era is further subdivided into periods, epochs, and ages.
