For example, 60 million years is a measure of absolute time. These are numerical representations of time, and they give us specific points of reference.We have a long record of events in absolute time but much of that occurred before humans were on Earth to write it down.We get these rock dates and ages with radiometric dating techniques that tell us how old rocks are based on their rate of decay.Relative time, also called chronostratic time tells us when events occurred relative to each other.How much of your life do you spend thinking about time? Time comes in different forms in geology, mainly absolute and relative.
