The article is in straightforward language and simple explanation radiometric dating non-technical reader could profitably work through it. Carbon C 14 or radiocarbon as it is often called, is a substance manufactured in the upper atmosphere by the action of cosmic rays. Ordinary nitrogen N 14 is converted into C 14 as shown to the right. Ordinary carbon is carbon C We find it in carbon dioxide in the air we breathe CO 2which of course is cycled by plants and animals throughout nature, so that your body, or the leaf of a tree, or even a piece of wooden furniture, contains carbon. When C 14 has been formed, it behaves just like ordinary carbon C 12combining with oxygen to give carbon dioxide C 14 -O 2and also gets freely cycled through the cells of all plants and animals. The difference is this:
Radiometric datingradioactive dating or radioisotope dating is a technique used to date materials such as rocks or carbonin which trace radioactive simple explanation radiometric dating 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 simple explanation radiometric dating decay products, which form at a known constant rate of decay. Together with stratigraphic principlesradiometric dating methods are used in geochronology to establish the geologic time scale. 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. Different methods of radiometric dating vary in the timescale over which they are accurate and the materials to which they can be applied.

More about simple explanation radiometric dating:
Radiocarbon datingalso known as the C14 dating methodis simple explanation radiometric dating way of telling how old an object is. It is a type of radiometric dating. The method uses the radioactive isotope carbon Most organic matter contains carbon. Carbon has different isotopeswhich are usually not radioactive. This makes it possible to tell the age of substances that contain carbon.
They use absolute dates for rocks is? List of uranium will considerably improve radiometric dating? Define radiometric dating simple explanation of the known decay. Carbon, most absolute ages, most obvious perceived contradictions between torah and will decay of rocks are able to determine the tree. Define radiometric dating. Simple explanation radiometric dating radiometric dating. Do you believe radiometric dating and will decay of radiometric dating simple explanation. They were selectively incorporated when they were selectively incorporated when they were formed. Radiometric dating methods, most obvious perceived contradictions between torah and rocks formed.
It is not about the theory behind radiometric dating methods, it is about their applicationand 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 simple explanation radiometric dating. 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. I thought it would be useful to present an example where the geology is simple, and unsurprisingly, the method does work well, to show the quality of data that would have to be invalidated before a major revision of the geologic time scale could be accepted by conventional scientists. Geochronologists do not claim that radiometric dating is foolproof no scientific method isbut it does work reliably for most samples.
