Describe the division of the geologic time scale using terms eon epoch and period

The geologic time scale is referred to as the system of chronological dating which is related to geological strata to time. It is used by palaeontologists, geologists and earth scientists to describe the relationship of events and timing that occurs during Earth’s history. The primary division of time is defined as eons. Eons follow a sequence of the Archean, the Hadean and the Proterozoic which are referred as Precambrian superon.

Eons are divided into an era whereby those eras are subdivided into periods, ages, and epochs. Eon, epoch, period and ages correspond with eonothem, series, systems and stage which are mostly used to refer to layers of rock which then stretches to geologic time in the history of the earth.
