Earth History Test

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.

• Faults show new index fossils

Which best describes how ice cores are important to the study of geologic history?

• They show unconformities, which signal changes in deposition.

• They hold index fossils, which are used to date the different ice cores.

• They contain evidence showing changes in the atmospheric composition over time.

• They follow the Law of Superposition, which gives reasons for extinctions of species.

In what type of rock would a geologist MOST likely find evidence of ancient life?

• sedimentary

• igneous

• metamorphic

Scientists studying rock layers classify the top layer as the most recent, followed by older layers that are uncovered as they dig deeper. Which law explains this method of relative dating?

• law of geologic continuity

• law of universal position

• law of lateral continuity

• law of superposition

states that younger rock is found above older rock when comparing undisturbed sedimentary rock layers

• trace fossil

• matter can't be created or destroyed

• atoms
