Final answer:
The geologic timeline is organized into eras, periods, and epochs based on major geological events and changes. For example, the Paleozoic era is divided into periods like Cambrian, Ordovician, Silurian, etc.
Step-by-step explanation:
The geologic timeline
The geologic timeline is organized into chunks of time called eras, periods, and epochs. These divisions are based on major geological events and changes in the Earth's history.
For example, the Paleozoic era is divided into periods such as Cambrian, Ordovician, Silurian, and more. Each period represents a distinct time period with its own unique characteristics and geological events.
Within each period, there are smaller divisions called epochs. These are even more specific time intervals and represent smaller-scale geological changes.
