Absolute dating is a method of estimating the age of a rock sample in years via radiometric techniques.
Short Answer: 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, but one does get such an estimate of true age from absolute dating.
Thermoluminescence: It determines the period during which certain object was last subjected to heat.
It is based on the concept that heated objects absorb light, and emit electrons. A Venn diagram depicts both dating methods as two individual sets.
Amino acid dating: Physical structure of living beings depends on the protein content in their bodies.
The changes in this content help determine the relative age of these fossils.
Radiometric dating, based on known rates of decay of radioactive isotopes in objects, allows a specific age of an object to be determined to some degree of accuracy.
Relative dating is a scientific process of evaluation used to determine the relative order of past events, but does not determine the absolute age of an object.Biostratigraphy: An extended version of stratigraphy where the faunal deposits are used to establish dating.Faunal deposits include remains and fossils of dead animals.The relative dating techniques are very effective when it comes to radioactive isotope or radiocarbon dating.However, not all fossils or remains contain such elements.There are several techniques employed in both sets of methods. Long Answer: Sciences such as geology, paleontology and archeology are very interested in identifying the age of objects found and these scientists sometimes use both relative dating or absolute dating to characterize the age of the objects they study.
