Relative dating is the science of determining the relative order of past events without Methods for relative dating were developed when geology first emerged as a Geologists still use the following principles today as a means to provide wide variety of environments supports this generalization (although cross-bedding.
Principles of Relative The Principle of Superposition tells us that deeper layers of rock are older than shallower layers Relative dating utilizes six fundamental principles to determine the relative age of a formation or event. For purposes of relative dating this principle is used to identify faults and erosional features within the rock record. The principle of cross-cutting states that any geologic feature that crosses other layers or rock must be younger then the material it cuts across.
Although this principle is generally applied to relative dating it is also the basis for evolution Chapter Contents:.
