Stratigraphy
The science of stratigraphy is important for the information it tells us about the rock record and how those rocks were originally deposited. The laws and principles set forth by early scientists help modern stratigraphers to know how sediment was originally deposited, to know which rock is older, and how to use fossils to help link different rock units to the same geologic time.
