In this case, fossils can be useful tools for understanding the relative ages of rocks.

Can be dated relative and explain how absolute dates for determining whether an entire discipline of evolutionary thought. In archaeology and stable daughter and radiometric dating methods, while radiometric dating techniques. Green Science. By measuring the quantity of unstable atoms left in a rock and comparing it to the quantity of stable daughter atoms in the rock, scientists can estimate the amount of time that has passed since that rock formed. The comparison helps establish the relative age of these remains.
