If I’m not wrong it’s Epochs and periods
Eons are divided into eras, which are further divided into periods. Each period is then subdivided into epochs.
The Geological eras can be divided into three major eras: Paleozoic, Mesozoic, and Cenozoic. These eras represent different periods in the Earth's history marked by significant geological and biological changes. Each era is further subdivided into periods, epochs, and ages.
Most scientists agree that there are 3 eras for every eon.
The geologic time scale is divided into four eras: the Precambrian, Paleozoic, Mesozoic, and Cenozoic eras. Each era represents a distinct span of time in Earth's history with characteristic geological and biological features.
The longest segments of geologic time are eons, which are divided into eras, which are further divided into periods, epochs, and ages. The current eon, the Phanerozoic Eon, has been ongoing for approximately the last 542 million years.
Eons are divided into eras, which are further divided into periods. Each period is then subdivided into epochs.
Geological eras can be divided into periods, epochs and ages.
Geological eras can be divided into periods, epochs and ages.
The geological time scale is divided into eons, each of which is further divided into eras. Eras are then divided into periods, and periods are further divided into epochs. This hierarchical structure allows for a systematic organization of Earth's history based on significant changes in the planet's geology, climate, and life forms over time.

because
Yes, epochs are further divided into eras in the geologic time scale. The geologic time scale is divided into eons, which are then broken down into eras, which are further divided into periods, epochs, and ages. Each division represents a significant geological time period characterized by distinct events or changes in Earth's history.
The geological time scale is the history of the earth. This is in the eras period and epochs.
Eras. I think eons , too.
