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.

According to the law of superposition, the oldest fossils are found 

• At the top of the rock layers
• Near the bottom of the rock layers
• In the middle of the rock layers
• Somewhat near the surface
