Question

use the law of superposition to choose the correct answer for the following questions about rock layer and relative age. which layer is older than layer 6? layer 8 which layers are younger than layer 4? layers 2 and 3 which layers were deposited before layer 5? layers 1 and 2 layers 7 and 9 layers 4 and 6

Explanation:

Step1: Recall law of superposition

In undisturbed rock - layers, older layers are at the bottom.

Step2: Analyze layers relative to Layer 5

Layers 1 and 2 are below Layer 5, so they were deposited before it.

Answer:

Layers 1 and 2
