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.
