Explanation:

The Geologic Time Scale (GTS) lists in chronological order the geological events. It's used ti meausure the durations of the geologic times. Geologists arrange these perioids depending on the approach or purpose or their research and the elements taken into consideration. Geological time has been divided into four Eons: Hadean, Archean, Proterozoic, and Phanerozoic. Each of these eons is divided into eras and each era into periods.
