Absolute dating involves determining a rocks 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. The geologic time scale is made possible by Nicolas Steno (see detailed information about him in the Background section of the Layers Upon Layers lesson).
With Stenos law of superposition, geologists could identify the relative age of various rock layers. Pupils. Investigate relative and absolute dating; determine the difference between the two dating systems; and apply this knowledge by creating a geologic timetable of their own.
