The geologic time scale is the “calendar” for events in earth history. it subdivides all time into named units of abstract time called—in descending order of duration— eons, eras, periods, epochs, and ages. the enumeration of those geologic time units is based on stratigraphy, which is the correlation and classification of rock strata. The geologic time scale is a means of measuring time based on layers of rock that formed during specific times in earth’s history and the fossils present in each layer. the main units of the geologic time scale, from largest (longest) to smallest, are: eon, era, period, epoch and age. each corresponds to the time in which a particular layer.
