Visualizing Geologic Time

This exercise is meant to help you visualize the vastness of geologic time since Earth’s formation, ~4.6 billion years ago. It is difficult for us to imagine the amount of time required for many geological processes to occur (e.g., formation of oceans or mountain ranges). The geologic time scale organizes the Earth’s history into a series of chronologic subdivisions that are defined by important geologic events in the Earth’s history. The largest of these time subdivisions are eons. Eons are then subdivided into eras. Eras are subdivided into periods, and periods are subdivided into epochs. We currently live in the Holocene epoch of the Quaternary period in the Cenozoic Era of geologic time. Once you have finished this exercise, you will realize what a tiny slice of time that represents relative to the vastness of geologic history.
