Rock layers names

Quick Answer. Scientists use two approaches to date rocks and fossils. Relative age dating is used to determine whether one rock layer (or the fossils in it) are older or younger than another base on their relative position: younger rocks are positioned on top of older rocks. Absolute age dating (or, radiometric dating) determines the age of a ...
