17. Chronostratigraphic

18. Strata = layers Stratigraphy = study of the rock layers

19. Chronostratigraphic The layers themselves Their placement in relation to each other No ages or dates inferred

20. Chronostratigraphic The layers themselves Their placement in relation to each other No ages or dates inferred Geochronologic Layers + Time inference (millions of years)
