Geologists have developed many metaphors to try to characterize the vastness of time separating important events in the history of Earth and its life. One of the most popular such metaphors scales this 4.54 billion year history into a familiar 365-day calendar year:
As a result, the history contained within these rocks cannot be as clearly interpreted. Our geologic time scale was constructed to visually show the duration of each time unit.

The principle of cross-cutting relationships states that a rock unit (or other geological feature, such as a fault) that is cut by another rock unit (or feature) must be older than the rock unit (or feature) that does the cutting. Imagine cutting a slice of bread from a whole loaf. Because of ...
geologic time, including present day, belongs to the Phanerozoic Eon. While the units making up the time scale are called geochronologic units, the actual rocks formed during those specific time intervals are called chronostratigraphic units. The actual rock record of a period is called a system, so rocks from the Cambrian Period are of the ...Chronostratigraphy is the branch of stratigraphy that studies the ages of rock strata in relation to time.. The ultimate aim of chronostratigraphy is to arrange the sequence of deposition and the time of deposition of all rocks within a geological region, and eventually, the entire geologic record of the Earth..
