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 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.

Which environmental condition MOST likely existed at the time a fossil formed?

• Organism remains were deposited in an area of open space.

• Organism remains were covered by lava flow.

• Organism remains were buried with little oxygen.

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.
