Explanation:
Scientists use the concept of relative dating principles to determine when the Great Oxidation event occurred.
Relative dating is the process of placing ancient event in their proper time sequence based on the relationship between rock lithologies.
- An event like the great oxidation will have significant chemical, biological and physical effect on the rock units.
