Principle of original horizontality
Principle of lateral continuity
Cross-cutting principle
Principle of fossil and fauna succession.
All of these principles helps establish succinct relationships between rock layers and what they contain. Fossils which are the preserved remains of organisms in rocks are very essential in relative dating of rocks.
