Radiometric dating simple english - gemstar guide plus not updating

Elements occur naturally in the earth, and they can tell us a lot about our Earth's past.Carbon, uranium and potassium are just a few examples of elements used in radioactive dating.

A particular isotope of a particular element is called a nuclide. That is, at some point in time, an atom of such a nuclide will spontaneously change into a different nuclide by radioactive decay.Together with stratigraphic principles, radiometric dating methods are used in geochronology to establish the geological time scale.Among the best-known techniques are radiocarbon dating, potassium-argon dating and uranium-lead dating.The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay.and is now the principal source of information about the absolute age of rocks and other geological features, including the age of fossilized life forms or the age of the Earth itself, and can also be used to date a wide range of natural and man-made materials.The method compares the amount of a naturally occurring radioactive isotope and its decay products, in samples. It is the main way to learn the age of rocks and other geological features, including the age of the Earth itself.

It may be used to date a wide range of natural and man-made materials.

By allowing the establishment of geological timescales, it provides a significant source of information about the ages of fossils and the deduced rates of evolutionary change.

Radiometric dating is also used to date archaeological materials, including ancient artifacts.

The amount of the isotope in the object is compared to the amount of the isotope's decay products.

The object's approximate age can then be figured out using the known rate of decay of the isotope.
