# Relative and absolute age dating of rocks

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.Carbon-14 moves up the food chain as animals eat plants and as predators eat other animals. It takes 5,730 years for half the carbon-14 to change to nitrogen; this is the half-life of carbon-14.After another 5,730 years only one-quarter of the original carbon-14 will remain.

Particular isotopes are suitable for different applications due to the type of atoms present in the mineral or other material and its approximate age.

We can absolute date materials but it will always have an uncertainty range, we can never know the age with infinite precision.
