geologic time scale
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 major divisions of Earth's history are typically divided into eons, eras, periods, and epochs. The current eon is the Phanerozoic, which is divided into eras such as Paleozoic, Mesozoic, and Cenozoic. Each era is further divided into periods, like the Jurassic period within the Mesozoic era. Periods can be subdivided into epochs, such as the Pleistocene epoch within the Quaternary period.
Geologists have divided Earth's history into manageable units called eons, eras, periods, and epochs. These divisions help scientists study and understand the Earth's geological and biological history over millions of years.
The table you are referring to is likely the Geologic Time Scale. It divides Earth's history into different time periods based on significant events and changes in the planet's geology, climate, and life forms. These time periods are typically grouped into eons, eras, periods, epochs, and ages.

The Earth's history is divided into geologic time periods, with the largest unit being eons, which are further divided into eras, periods, epochs, and ages. The current eon we are in is the Phanerozoic eon, divided into the Paleozoic, Mesozoic, and Cenozoic eras. Each division represents significant changes in Earth's geological and biological history.

So you can understaned it much more better and think about it!
Geologists designate different time periods in Earth's ancient past using the geologic time scale, which is divided into eons, eras, periods, epochs, and ages. These divisions are based on significant events in Earth's history, such as mass extinctions, major geological or biological changes, or the appearance of key fossils. The boundaries between these time periods are defined by specific markers in the rock record, such as changes in fossil assemblages or shifts in sedimentation patterns. Geologists use a combination of stratigraphy, radiometric dating, and fossil evidence to accurately assign ages to these time periods.
