A geologist identifies the 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.

Which is the best reason for scientists to study ice cores obtained from Earth’s ice caps?

Which best describes uniformitarianism?

• The time it takes for erosion to occur has changed since Earth first formed.

• The movement of the continents no longer occurs because of changes in ocean currents.

• The processes that shape the Earth continue as they have since the Earth formed.

• The formation of rock layers has slowed because humans have altered the environment.
