  1. Relative Dating

  2. Original Horizontality • Layers of sediment are deposited evenly, with each new layer formed horizontally over older layers

  3. Superposition • In an undeformed sequence of rocks, each layer is younger than the one below.

  4. Cross Cutting • An igneous intrusion or fault that cuts through preexisting rock is younger than the rock it cuts through

  5. Inclusions • Inclusions are pieces of rock contained within another • Any inclusion is older than the rock containing it.

  6. Faunal Succession • Fossil organisms succeed one another in a definite, irreversible order • Fossils can be used to correlate rocks of similar age in different regions

  7. Unconformities • Disruptions in the rock record caused by folding, uplifting, and erosion

  8. FAULT INTRUSIONS EROSION FOLD
