Jun 13, 2019 · Using dazzling detective skills, geologists created a calendar of geologic time. They call it the Geologic Time Scale. It divides Earth’s entire 4.6 billion years into four major time periods. The oldest — and by far the longest — is called the Precambrian. The history of the earth is broken up into a hierarchical set of divisions for describing geologic time. As increasingly smaller units of time, the generally accepted divisions are eon, era, period, epoch, age. In the time scale shown at left, only the two highest levels of this hierarchy are represented. The Phanerozoic Eon is shown along the ...The geologic time scale is often shown with illustrations of how life on Earth has changed. It sometimes includes major events on Earth, too, such as the formation of the major mountains or the extinction of the dinosaurs.
