Question

Quizplus · Accepted Answer

The Geologic Time Scale is divided into eons, eras, periods, and epochs. Eons are the largest division and are based on the Earth's major changes in geology and life forms. Eras are the second-largest division and are based on significant changes in the fossil record. Periods are smaller divisions within eras, characterized by the appearance and disappearance of specific groups of organisms. Epochs are the smallest divisions and are based on shorter periods of time within a certain period. Therefore, epochs are the least inclusive division.
