Three rules of relative dating

Rated 3.92/5 based on 915 customer reviews

Relative dating utilizes six fundamental principles to determine the relative age of a formation or event.

The science of geology is founded on basic principles that are useful for making observations about the world around us.

This follows due to the fact that sedimentary rock is produced from the gradual accumulation of sediment on the surface.

Therefore newer sediment is continually deposited on top of previously deposited or older sediment.

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

Once a rock is lithified no other material can be incorporated within its internal structure.
