These rates of decay are known, so if you can measure the proportion of parent and daughter isotopes in rocks now, you can calculate when the rocks were formed.Because of their unique decay rates, different elements are used for dating different age ranges.Others measure the subatomic particles that are emitted as an isotope decays.Some measure the decay of isotopes more indirectly.

Isotopes are important to geologists because each radioactive element decays at a constant rate, which is unique to that element.

The atoms of some chemical elements have different forms, called isotopes.

These break down over time in a process scientists call radioactive decay.

These strata are often most visible in canyons or gorges which are good sites to find and identify fossils.

Understanding the geologic history of an area and the different strata is important to interpreting and understanding archaeological findings.

This principle presumes that the oldest layer of a stratigraphic sequence will be on the bottom and the most recent, or youngest, will be on the top.
