Geologic time scale conversion chart
© 2020 The Geological Society of America, Inc. A geologic time scale is composed of standard stratigraphic divisions based on rock sequences and is calibrated in years (Harland and others, 1982). Over the years, the development of new dating methods and the refinement of previous methods have stimulated revisions to geologic time scales. Geological Time Chart Check out whats going on at the different times going back millions or billions of years in the time table below. We are currenty building this geologic site and adjusting times and events listed on this geological time scale.

Description: Students will create a timeline of Earth history in the classroom and To provide students with a visual comprehension of the scale of geologic time This website, Time Scale Creator, enables you to explore and create charts of Not all of the items shown in Table 1 are shown on the chart because of space limitations. For more information on the geologic time scale, see: • www.uky.edu/ Unraveling time and the Earth's biologic history are arguably geology's most important contributions to humanity. Yet it is very difficult for humans to appreciate 24 Feb 2012 Geologic Time Scale.

The geologic time scale is a system used by scientists to describe Earth's history in terms of major geological or paleontological events (such as the formation of a new rock layer or the appearance or demise of certain lifeforms). Geologic time spans are divided into units and subunits, the largest of which are eons.
The table of geologic time spans, presented here, agree with the nomenclature, dates and standard color codes set forth If you think of all of Earth's history as having taken place in just one day, then the pie-chart above is a 24 hour clock. The Earth forms at 12:00 am, and cools down

Scaling this large amount of time to our calendar year, each of the 12 months of the geologic calendar year represents 383 million years (4.6 billion / 12).
