understanding the law of superposition kaiparowits plateau glen canyon use the law of superposition to choose the correct answer for the following questions about rock layers and relative age. which layer is older than layer 6? which layers are younger than layer 4? which layers were deposited before layer 5?
Answer
Explanation:
Step1: Recall law of superposition
In an undisturbed sequence of sedimentary rocks, the oldest layers are at the bottom and the youngest are at the top.
Step2: Find layer older than Layer 6
Layers 7, 8, 9, 10 are below Layer 6, so they are older.
Step3: Find layers younger than Layer 4
Layers 1, 2, 3 are above Layer 4, so they are younger.
Step4: Find layers deposited before Layer 5
Layers 6, 7, 8, 9, 10 are below Layer 5, so they were deposited before it.
Answer:
- Layers older than Layer 6: 7, 8, 9, 10
- Layers younger than Layer 4: 1, 2, 3
- Layers deposited before Layer 5: 6, 7, 8, 9, 10
