Question
### Relative Dating of Geological Objects #### Diagram Description: The diagram shows a cross-sectional view of various geological layers and intrusions, labeled A to L, intersected by two red lines labeled with endpoints B, C, and K. 1. **Strata/Layer Identification:** - Layers are differentiated by colors and labeled from A (top) to L (bottom). - Layering represents different periods of sediment deposition. 2. **Intrusions and Faults:** - A black, vertical intrusion cuts through the layers diagonally from top to bottom. - Two red line intrusions (faults) traverse the diagram, intersecting some layers and the black intrusion. #### Relative Age Determination: By applying the principles of relative dating (superposition, cross-cutting relationships, and inclusions), geological objects are ranked from oldest to youngest: 1. **L:** Oldest layer at the bottom. 2. **J:** Layer above L. 3. **I:** Above J. 4. **H:** Above I. 5. **G:** Above H. 6. **F:** Next layer above, colored light blue. 7. **E:** Green layer above F. 8. **D:** Light purple layer above E. 9. **C:** Yellow layer above D. 10. **B:** Green layer above C. 11. **A:** Topmost layer. 12. **Black Diagonal Intrusion:** Cuts through all layers from top to bottom indicating it is younger than all disturbed layers. 13. **Red Line Intrusions (Faults) ending at B-C and B-K:** Two faults cutting through the diagram's layers and the black intrusion, indicating they are the youngest features. These principles help in understanding the sequence of geological events that have shaped the region.
