Relative dating vs radioactive dating

Relative dating is used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages.Absolute dating is used to determine a precise age of a fossil by using radiometric dating to measure the decay of isotopes, either within the fossil or more often the rocks associated with it.Chronometric dating has advanced since the 1970s, allowing far more accurate dating of specimens.Adrian Grahams began writing professionally in 1989 after training as a newspaper reporter.This group is dedicated to providing information about the scientific method as it concerns the idea of evolution in the Creation/Evolution debate. The site provides background information about stratigraphic principles and relative time, biostratigraphy (using fossils for relative dating), and radiometric dating.

Together with stratigraphic principles, radiometric dating methods are used in geochronology to establish the geological time scale.Radiometric dating or radioactive dating is a technique used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporated when they were formed.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.But, how can we determine how old a rock formation is, if it hasn’t previously been dated?Scientists can use certain types of fossils referred to as index fossils to assist in relative dating via correlation.
