Question

How do scientist use layers of rock to determine when the Great Oxidation event occured?

Answer 1

Answer:

Using the concept of relative dating

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.
• Rocks that form during this period in time will have very unique chemical signatures.
• Therefore, by studying these rocks, the age of the layer can be fixed when we compare it to the standard geological column.
