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 earliest Earth crust probably forms similarly out of similar material. On Earth the pluvial period starts, in which the Earth's crust cools enough to let oceans form. c. 4,404 Ma – First known mineral, found at Jack Hills in Western Australia. Detrital zircons show presence of a solid crust and liquid water.
The geologic time scale, proportionally represented as a log-spiral with some major events in Earth's history. A megaannus (Ma) represents one million (10 6) years.. The geologic time scale or geological time scale (GTS) is a representation of time based on the rock record of Earth.
If you create a single row template, it can easily be embedded in a different template with different scale. The single row template will be automatically cropped to fit the parent template. See how {{Geological eras}} and {{Geological periods}} are embedded in {{Extinction events graphical timeline}} Different browsers have different ways of ...
The first eon in Earth's history, the Hadean, begins with the Earth's formation and is followed by the Archean eon at 3.8 Ga. [2]: 145 The oldest rocks found on Earth date to about 4.0 Ga, and the oldest detrital zircon crystals in rocks to about 4.4 Ga, [34] [35] [36] soon after the formation of the Earth's crust and the Earth itself.
If the template has a separate documentation page (usually called "Template:template name/doc"), add [[Category:Graphical timeline templates]] to the <includeonly> section at the bottom of that page.
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.
