The science of determining the age of
geological structures, rocks, and fossils,
and placing them in the context of geological
time. Dating can be carried out by
identifying fossils of creatures that lived
only at certain times (marker fossils), by
looking at the physical relationships of
rocks to other rocks of a known age, or by
measuring how much of a rock's radioactive
elements have changed since the rock was
formed, using the process of radiometric
dating.
