Dating Rocks Two major categories of geologic dating techniques exist: relative dating and absolute age determinations. Relative dating determines e order in which a sequence of geologic events (e.g., volcanic eruptions, mountain building, sea-level rise, and deposition of sedimentary strata) occurred, but not how long ago e events happened. Compared to absolute dating, what is an advantage of relative dating? A single fossil can be dated by itself. e actual age of a fossil can be determined. Fossils do not need to be arranged in different layers of rock. ere is no limit to e age range of e fossils being dated. Relative dating tells scientists if a rock layer is older or younger an ano er. is would also mean at fossils found in e deepest layer of rocks in an area would represent e oldest forms of life in at particular rock formation.
