geologic time scale date page 2 keep going! answer the questions below. 3. using the letters shown in the diagram to the right, list the rock layers and formations in order from oldest to youngest. cite evidence from the diagram to explain your answer. key sedimentary rock intrusion extrusion fault
Answer
Brief Explanations:
The principle of superposition states that in undisturbed sedimentary rock layers, the oldest layers are at the bottom. Also, intrusions and faults are younger than the rocks they cut through. Layer E is at the bottom, so it is the oldest. Then D, C, B in sequence as they are above E. Intrusion G cuts through layers E - B, so it is younger than those layers. Fault F cuts through G and other layers, so it is younger than G. Extrusion A is on the top, so it is the youngest.
Answer:
E, D, C, B, G, F, A
