Compare and contrast relative dating and absolute dating
As the parent decays to daughter, the ratios change and the straight line remains but becomes angled.
The slope of the line equals the number of half-lives the parent isotope has passed since solidification.
The usual isotope of carbon found in living organisms, ¹²C, is stable, while ¹⁴C is not stable.
It is formed when cosmic radiation strikes ¹⁴N (Nitrogen), converting it into ¹⁴C, and it decays back into ¹⁴N, with a half-life of 5730 years.
Uniformitarian geologists consider this form of dating strong evidence that the Earth is billions of years old.
However, research by creationists has revealed a large number of problems with radiometric dating.
Radioactive decay is a spontaneous process in which an isotope (the parent) loses particles from its nucleus to form an isotope of a new element (the daughter).
The rate of decay is conveniently expressed in terms of an isotope's half-life, or the time it takes for one-half of a particular radioactive isotope in a sample to decay.
Carbon-14 dating is a radiometric dating technique used to deduce the approximate age of organic remains by measuring the quantity of the isotope ¹⁴C in the sample and comparing it with the current atmospheric level.Age of deposition should not be confused with the date of material enclosed in deposit.
