Geologic Time Scale Chart

The Geologic Time Scale Chart is a way scientists organize Earth's history into chronological segments based on major events like the appearance and extinction of species, volcanic activity, and climate changes. It divides Earth's 4.6-billion-year history into eons, eras, periods, epochs, and ages, helping us understand when significant evolutionary and geological events occurred. Think of it as a detailed timeline that shows how Earth has transformed over billions of years, highlighting the sequence and relative timing of key developments in Earth's deep history.
