Relative chemical dating
Relative dating does not provide actual numerical dates for the rocks.
Fossils are important for working out the relative ages of sedimentary rocks.
The radiometric dating is another crucial technique through which the exact age can be obtained.
Radiocarbon dating measures radioactive isotopes in once-living organic material instead of rock, using the decay of carbon to nitrogen C has a half life of years which means that only half of the original amount is left in the fossil after years while half of the remaining amount is left after another years.
Absolute Age The actual age, in years, of a rock or fossil.
Suppose you find a fossil at one place that cannot be dated using absolute methods.
That fossil species may have been dated somewhere else, so you can match them and say that your fossil has a similar age.
The relative and absolute dating comparison dating is the technique to ascertain the exact numerical age of the artifacts, rocks or even sites, with using the methods like carbon dating and other.
