The geologic time scale is a system used by geologists and paleontologists to organize Earth's history into chronological units based on significant geological and biological events. It divides time into eons, eras, periods, epochs, and ages, showcasing the development of life and major geological changes over approximately 4.6 billion years. Visually, it resembles a long, vertical chart or timeline, with each unit represented in a hierarchical format, often color-coded to indicate different time spans and major events.
