Unconformities
Unconformities are an important part of the stratigraphic record. They represent periods of non-deposition and erosion. Knowing how to interpret and identify unconformities can help a geologist piece together the history of the stratigraphic record, and how that sequence of rocks relates to other sequences.

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.

Relative Time
Geologists can use several principles to help relate the sequence of events to determine the relative time scale for a particular sequence of rocks. Understanding these principles helps a geologist place the rocks within the confines of the geologic time scale.
