WebOct 20, 2013 · For centuries scholars sought to determine Earth’s age, but the answer had to wait for careful geologic observation, isotopic analyses of the elements and an understanding of radioactive decay WebLikewise, geologists created the geologic time scale to organize Earth’s history into eons, eras, periods, and epochs. While a human life spans decades, geologic time spans all of Earth’s history—4,600 million …

The geologic time scale, or geological time scale, (GTS) is a representation of time based on the rock record of Earth.
