Question

the image shows sedimentary rock layers with index fossils and a fault. which statement accurately describes the rock layers? layer 8 is older than layer 1. layer 3 is younger than layer 6. layer 4 and layer 10 are the same relative age. layer 2 and layer 9 are the same relative age.

Explanation:

In sedimentary rock layers, the principle of superposition states that lower layers are generally older. Also, if there is a fault, layers on either side of the fault that align can be considered the same relative age. Layer 2 and layer 9 have the same index - fossils and are on either side of the fault, indicating they are the same relative age.

Answer:

Layer 2 and layer 9 are the same relative age.
