This is different to relative dating, which only puts geological events in time Most absolute dates for rocks are obtained with radiometric methods.These use radioactive minerals in rocks as geological clocks.Relative dating simply orders stratigraphic units, or layers of rock, from oldest to youngest.There are several rules or laws in place that provide scientists with the means to determine which layer is oldest, youngest and the relative ages of the layers in between.The Law of Superposition indicates that the oldest layers will be on the bottom, the youngest on the top.
However, they will not be able to conclude that Layer A is X number of years older than Layer B.Geologists often need to know the age of material that they find.They use absolute dating methods, sometimes called numerical dating, to give rocks an actual date, or date range, in number of years.Each original isotope, called the parent, gradually decays to form a new isotope, called the daughter.Each isotope is identified with what is called a ‘mass number’.
