Much like the principle of cross-cutting, the Principle of Inclusions relatively dates objects based on their placement within other earth materials.

Nemo is the oldest, followed by Twilight, Hunger Games, and the Avengers Again, we have not stated anything about the actual age of these movies, we've just put them in order relative to one another.The same thing can be done with geologic features in a rock outcrop.The Principle of Fossil Succession states that groups of fossils (called fossil assemblages) proceed one another in a regular and determinable manner.Often when geologists examine rock outcrops like the one illustrated above they are interested in not only the types of rocks present, but the order in which they formed.The Principle of Original Horizontality states that due to the influence of gravity all sediment is originally deposited horizontally.

In other words, as sediment fills a depositional basins we would expect the upper most surface of the sediment to be parallel to the horizon. Using this principle we can than assume that sedimentary layers which have been deformed/folded must have been deformed after all affected layers have been deposited.Nicolas Steno, William Smith, Georges Cuvier, Alexandre Brongniart, and James Hutton developed the basic rules for the science of stratigraphy.Relative dating uses the principles or laws of stratigraphy to order sequences of rock strata.When they put events in chronological order like they use Relative Dating.We do this all the time in our regular day to day lives.Steno recognized that fossils represent organisms that became buried in sediment, which later turned into rock.
