Which principles of relative dating did you use to answer e previous question? Superposition and Cross-Cutting Relationships. 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.
