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.
• Faults are the same age as the layers they cut through.

Which statement best describes the Law of Superposition?

• Each sedimentary layer of rock represents 1,000 years of Earth's age, much like the rings of a tree.
• In undisturbed layers of sedimentary rocks, the upper rock layers are older than the lower rock layers.
• In undisturbed layers of sedimentary rock, the lowest layers contain the older rocks.
• Rocks that form near volcanoes are older than surrounding rock.
