Difference between relative dating and absolute dating

However, not all fossils or remains contain such elements.Absolute dating is the process of determining an age on a specified chronology in archaeology and geology.These are called relative and absolute dating techniques.Absolute dating, also called numerical dating, arranges the historical remains in order of their ages.These remains are subjected to dating techniques in order to predict their ages and trace their history.This Buzzle post enlists the differences between the absolute and relative dating methods.

Relative dating uses observation of location within rock layers, while radiometric dating uses data from the decay of radioactive substances within an object.For example, carbon dating is used to determine the age of organic materials.Once something dies, it ceases taking in new carbon-14, and the existing carbon-14 within the organism decays into nitrogen at a fixed rate.An example of this type of aging includes rocks in Canada that scientists identified as being hundreds of million years old.Absolute age is more straight-forward and does not require any other objects for comparison.

Scientists measure the proportion of carbon-14 left in the organism to determine its age.
