How is the geologic time scale divided?
GPT 3.5
The geologic time scale is divided into various time periods, which are subdivisions of eons, eras, and periods. The largest divisions are eons, which are the longest and are divided into eras. Eras are then divided into periods, and periods are further divided into epochs and ages. Each division represents a significant change in the Earth's geologic history, such as major geological events, changes in climate, or the appearance and extinction of certain species.
