The first shows the entire time from the formation of the Earth to the present, but this gives little space for the most recent eon. The second timeline shows an expanded view of the most recent eon. In a similar way, the most recent era is expanded in the third timeline, the most recent period is expanded in the fourth timeline, and the most ...

The geologic time scale or geological time scale (GTS) is a representation of time based on the rock record of Earth. It is a system of chronological dating that uses chronostratigraphy (the process of relating strata to time) and geochronology (a scientific branch of geology that aims to determine the age of rocks).
Geologic time is the timescale used to calculate dates in the planet's geologic history from its origin (currently estimated to have been some 4,600 million years ago) to the present day. Radiometric dating measures the steady decay of radioactive elements in an object to determine its age. It is used to calculate dates for the older part of ...
To change this template's initial visibility, the |state= parameter may be used: {{Geological history of Earth | state = collapsed}} will show the template collapsed, i.e. hidden apart from its title bar. {{Geological history of Earth | state = expanded}} will show the template expanded, i.e. fully visible.
It is recommended not to use this parameter unless absolutely necessary. See Template:Geological range for more information. image_map Reconstruction of the Earth as it appeared during the geologic time span. caption_map Caption for the above image. image_outcrop Picture of a rock outcrop with rocks dating to the geologic time span. caption_outcrop
A major achievement of geochronometry is the documentation of geologic time, as represented in geologic time scales. A geologic time scale is a scheme that integrates the geochronologic subdivisions of geologic time and their absolute ages and durations. The latest version of the geologic time scale was published in 2004, [6] and includes a ...
This category contains events which happened in the Geologic timescale category, a division of the geologic time scale. See geologic time scale for information about its divisions and how they relate to each other.
