Explanation / Answer

From the careful observation of the given map, the geological events from oldest to youngest are as follows :

11. Uplift and erosion, forming modern day surface

10. Ocean rise or land subsides, deposition of E, forming UC3

9. Tilting, uplift and erosion of A, F, I, B

8. Ocean rise or land subsides - deposition of F, I, B forming UC2

7. Fault G

6. Intrusion of C

5. Uplift and erosion of D, H, A

4. Folding of D, H, A

3. Ocean rise/ land subsides, deposition of H and A, forming UC1

2. Uplift and erosion of unknown rock layer exposing gneiss, layer D

1. Formation of gneiss, layer D
