Which statement best describes the Law of Superposition?

• Each sedimentary layer of rock represents 1000 years of Earth's age, much like the rings of a tree.
• In undisturbed layers of sedimentary rock, 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.
