Relative and radiometric dating
Another example of radiometric dating is the dating of the age of geological formations on earth. Short Answer: Radiometric dating is one type of absolute dating.
The term relative dating is distinguished from absolute dating to make it clear that one does not get a specific estimate of the age of an object from relative dating…
Both are attempting to get information on the history…
Carbon 14 dating is the best known example of radiometric dating, but there are many others.
All ordinary matter is made up of combinations of chemical elements, each with its own atomic number, indicating the number of protons in the atomic nucleus.
Elements exist in different isotopes, with each isotope of an element differing in the number of neutrons in the nucleus.
It may be used to date a wide range of natural and man-made materials.
Fossils may be dated by taking samples of rocks from above and below the fossil's original position.
The decay may happen by emission of particles (usually electrons (beta decay), positrons or alpha particles) or by spontaneous nuclear fission, and electron capture.As we pointed out in these two articles, radiometric dates are based on known rates of radioactivity, a phenomenon that is rooted in fundamental laws of physics and follows simple mathematical formulas.Dating schemes based on rates of radioactivity have been refined and scrutinized for several decades.The latest high-tech equipment permits reliable results to be obtained even with microscopic samples.
Radiometric dating is self-checking, because the data (after certain preliminary calculations are made) are fitted to a straight line (an "isochron") by means of standard linear regression methods of statistics.Radiometric dating is far more specific in formation analysis.
