Which supports the theory that some mountains were once at the bottom of an ocean?

• There are underwater mountains on the ocean floor today.

• Freshwater rivers flow to the ocean.

• Fossils of marine organisms are found on the tops of some mountains.

• Both mountains and ocean floors have similar minerals in their rocks.

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.

A geologist identifies identical index fossils in rock layers from two different areas. Which conclusion is best supported by this discovery?

• The deposition rate of the two rock layers was identical.

• The fossil organism evolved independently in the two separate areas.

• The two rock layers were deposited at approximately the same time.

• The index fossil will also occur in sediment deposited on top of these rock layers.
