The site also provides fact sheets on the age of the Earth and isochron dating.
Students take an informational tour to gain a basic understanding of geologic time, the evidence for events in Earth’s history, relative and absolute dating techniques, and the significance of the Geologic Time Scale.
Basic understanding of how radiometric dating works is useful.
This lesson is highly simplified, and the powerpoint describes everything the student will need to know for the activity.
The site provides background information about stratigraphic principles and relative time, biostratigraphy (using fossils for relative dating), and radiometric dating.
These techniques are often combined together to get the most detailed dating information from a rock sequence.
Methods of dating rocks Absolute dating involves determining a rock’s actual age as a number of years, whereas relative dating methods provide an estimate of the age of a rock by comparing it to rocks of a known age The Geological Time Scale has been created by combining both absolute and relative dating methods.
