Geologists use radiometric dating to estimate how long ago rocks formed, and to infer the ages of fossils contained within those rocks. Radioactive elements decay The universe is full of naturally occurring radioactive elements. Radioactive atoms are inherently unstable; over time, radioactive "parent atoms" decay into stable "daughter atoms. When molten rock cools, forming what are called igneous rocks, radioactive atoms are trapped inside. Afterwards, they decay at a predictable rate.

It is not about the theory behind radiometric dating methods, it is about their application , and it therefore assumes the reader has some familiarity with the technique already refer to "Other Sources" for more information. As an example of how they are used, radiometric dates from geologically simple, fossiliferous Cretaceous rocks in western North America are compared to the geological time scale. To get to that point, there is also a historical discussion and description of non-radiometric dating methods. A common form of criticism is to cite geologically complicated situations where the application of radiometric dating is very challenging. These are often characterised as the norm, rather than the exception.
Radiometric Dating and the Geological Time Scale
In Part 1 and Part 2 of this series, we called atheist Roger Lewin and agnostic Richard Milton as witnesses against the reliability of radiometric dating. I have noticed something curiously paradoxical when reading scholarly books by many anti-Darwinists. Meyer, etc. They accept the age designations of rocks and fossils and of the earth by evolutionists without challenge. Why is this?
Asked by Wiki User. Radiometric measurement is based on the decay of certain elements, the rate of which is a known scientific fact. Radiometric dating is just one method todate materials.
