The following five timelines show the geologic time scale to scale. The first shows the entire time from the formation of Earth to the present, but this gives little space for the most recent eon.

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 Geologic Time Scale or Geological Time Scale (GTS) is a chronological framework that organizes Earth?s history into various units based on geological and paleontological evidence. It divides Earth?s 4.6 billion-year history into hierarchical units such as eons, eras, periods, epochs, and ages.

The geologic time scale (GTS) is a chronological framework that organizes Earth?s 4.6 billion-year history based on major geological and biological events. It allows scientists to classify rocks and fossils not just by type or age, but by their place in the grand history of the planet.

The Geologic Time Scale above is a helpful reference to use along with the information provided below. The left half shows a timeline of Earth?s geologic history which is split into Eons, Eras, Periods, and Epochs and how many millions of years ago (MYA) these occurred.

The modern Geologic Time Scale as shown above is a compendium of both relative and absolute age dating and represents the most up-to-date assessment of Earth's history.

Geologists have divided Earth's history into a series of time intervals. These time intervals are not equal in length like the hours in a day. Instead the time intervals are variable in length. This is because geologic time is divided using significant events in the history of the Earth.

Why a geological time scale? In our daily lives, we measure time in days, years or centuries. But these units are too small to describe the history of the planet.. Geological processes: the formation of a mountain, the opening of an ocean, continental drift, etc. span millions, even billions of years. Geologists have therefore created a scale adapted to these colossal durations: the geological ...
