How is time divided?
In geological time, 4.5 billion years is called "deep time." Anything less than that is considered quick in a geological scale.Time is divided first into eons. Eons are divided into eras, and eras are divided into Systems, also called Periods. Periods are then divided into Series (Epochs) and then Stages (Ages) and lastly Chronozones. The following are all of the eons, eras, and periods in Earth's history.
