Long before geologists tried to quantify the age of the Earth they developed techniques to determine which geologic events preceded another, what are termed "relative age” relationships.

These techniques were first articulated by Nicolas Steno, a Dane living in the Medici court of Italy in the 17th C.

This worldview is often injected into public high school and university curricula.

Materialistic naturalism, as a worldview, is vacuous because it discounts the Creator and has clearly been shown to be a dead end.

Absolute time measurements can therefore be used to calibrate the relative time scale, producing an integrated geologic or "geochronologic" time scale that combines both types of data, as is depicted here.

This geologic time scale is based upon data from Harland et al., (1990) and Gradstein and Ogg, (1996).

Relative time - named subdivisions of the Earth's geology in a specific order (for example, the "Cambrian Period", followed by the "Ordovician Period", and "Silurian Period").

Most of these subdivisions are recognized globally on the basis of their relative position in the Earth's stratigraphy and their fossil content.

The time scale at left is both a reference and a key to the display cases at the museum ­ click on a geologic period to go to that case.

Note that in the United States it is common to break the Carboniferous into two periods, the Pennsylvanian and the Mississippian, as is done in our museum. Andrew Mac Rae for the use of the time scale image and the short essay below.

Free online classes in geology allow students to access course materials that include lectures, labs, handouts and assignments.
