Which statement is true?

• The oldest layers of rock and soil are closest to the surface of the earth
• The youngest layers of rock and soil are farther away from the surface of the earth.

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.

Many fossils of large amphibians were found in an area that is currently barren desert. Which is most likely true?

• The climate of the area was once much wetter than it is now.
• Amphibians were once better at surviving in dry environments.
• The amphibians migrated there after a catastrophic event destroyed their habitats.
• The amphibians are not native to the area and their bones were brought there by other animals.
