The index fossil of a type of trilobite is discovered in layer A of a set of rock layers found at three different sites of a field investigation. Which conclusion can be made about the rocks in layer A at all three sites?

• The rocks are all different ages
• The rocks are all about the same age
• The rocks were formed from melting magma

What role do faults play in the Law of Superposition?

• Faults create new types of rock.
• Faults are younger than the layers they cut through.

• Organisms have not changed significantly over time.
• All organisms from Earth's history have become extinct.
• Organisms have evolved from simple to complex forms.
