Review for Mastery Assess It 3

What is the principle of uniformitarianism?

• Geological processes that occur today once occurred in the past.

• The concept that Earth's features were formed by sudden, short-lived, violent events.

• The belief that Earth's processes are unpredictable and random.

• The theory that Earth's processes are influenced by extraterrestrial forces.

What are the two main types of fossils?

• Body fossil

• Trace fossil

• Index fossil

• Cast and mold fossil

Explain how relative dating is used to determine the age of fossils.

• By measuring the radioactive decay of isotopes in the fossil.

• By comparing the fossil's position in rock layers to other fossils.

• By using the fossil's color and texture.

• By analyzing the fossil's chemical composition.

Analyze the image below. The fossils in each of the layers shown in the image are found in many locations. These organisms lived for a short period of geologic time. To which classification do these fossils belong?

• Range fossils

• Microfossils

• Index fossils

• Trace fossils

What evidence supports the theory of plate tectonics?

• The presence of similar fossils on different continents.

• The uniform distribution of earthquakes around the world.

• The constant size of Earth's continents.

• The lack of volcanic activity along plate boundaries.

How do convection currents in the Earth's mantle affect plate movement?

• They cause the plates to move towards each other.

• They cause the plates to move away from each other.

Explain the concept of mass extinction and its impact on Earth's biodiversity.

• Mass extinction is a gradual process that increases biodiversity over time.

• Mass extinction is a rapid decrease in biodiversity, leading to the loss of many species.

• Mass extinction is a slow process that has no impact on biodiversity.

• Mass extinction is a natural process that always results in the emergence of new species.
