Pretty obvious that the dike came after the rocks it cuts through, right?With absolute age dating, you get a real age in actual years.The narrower a range of time that an animal lived, the better it is as an index of a specific time.No bones about it, fossils are important age markers.To determine the relative age of different rocks, geologists start with the assumption that unless something has happened, in a sequence of sedimentary rock layers, the newer rock layers will be on top of older ones. This rule is common sense, but it serves as a powerful reference point.Geologists draw on it and other basic principles ( to determine the relative ages of rocks or features such as faults.An absolute age is one determined usually by mass-spectrometry where an isotope is measured and then an age can be calculated (a very very basic explanation).So in the end you can say this fossil is 50 thousand years old (always with an associated uncertainty).

So I can say the second layer is younger than the first and older than the third but I have no idea whether the cake is 5 minutes or 5 million years old.

Here is an easy-to understand analogy for your students: relative age dating is like saying that your grandfather is older than you.

Absolute age dating is like saying you are 15 years old and your grandfather is 77 years old.

Relative age dating also means paying attention to crosscutting relationships.

Say for example that a volcanic dike, or a fault, cuts across several sedimentary layers, or maybe through another volcanic rock type.
