What are the sequence of events that are shown in the diagram above? List down from the oldest to the youngest. 2. What are the principles in stratigraphy that they used? Self -Evaluation Archaeologists use techniques developed in geology to determine the age (relative and absolute) of artifacts unearthed from the ground. Research and write a short report (200 to 300 words) on this topic. ADDITIONAL RESOURCES: 1. Lutgens, F. K., Tarbuck, E. J., & Tassa, D. (2013). Essentials of geology (11th ed.).
