Scientists use the geologic time scale to organize Earth’s history. This scale divides the history into several different units that include eons, eras, periods, and epochs. These divisions are based on significant changes in Earth’s geology, climate, and biodiversity, often marked by mass extinctions, changes in the layers of rock, and the fossil record.
