Which of the following best describes how fossil evidence supports the scientific theory of evolution?

• Fossils show that all species have remained unchanged over time.

• Fossils provide evidence that living things evolved from earlier species.

• Fossils are only found in certain parts of the world.

• Fossils are not related to the theory of evolution.

Explain how genetic variation contributes to the process of natural selection.

• Genetic variation has no impact on natural selection.

• Genetic variation allows some individuals to survive and reproduce more successfully.

• Genetic variation decreases the chances of survival for all individuals.

• Genetic variation is eliminated by natural selection.

Which of the following is an example of how physical evidence supports the theory that Earth has evolved over geologic time?

• The presence of similar rock layers in different continents.

• The existence of only one type of rock on Earth.

• The lack of any changes in Earth's surface over time.

• The uniform distribution of fossils across all rock layers.

Identify the pattern within the rock cycle that relates to surface events such as weathering and erosion.

• Weathering and erosion break down rocks into smaller particles.

• Weathering and erosion create new rocks instantly.

• Weathering and erosion have no effect on the rock cycle.

• Weathering and erosion only occur in volcanic regions.

Describe how the movement of Earth's crustal plates can lead to mountain building.

• Crustal plates move apart, creating valleys.

• Crustal plates collide, causing the land to be pushed upward.

• Crustal plates remain stationary, preventing any changes.

• Crustal plates sink into the mantle, forming mountains.

How does the fossil record provide evidence for the theory of evolution?

• It shows that all species appeared at the same time.

• It demonstrates a progression of species from simple to more complex forms.

• It indicates that species have always been the same.

• It suggests that species do not change over time.

What role do environmental factors play in the process of natural selection?

• They have no role in natural selection.

• They determine which traits are advantageous for survival.

• They eliminate all genetic variation.

• They ensure that all individuals survive equally.

Which of the following is a result of plate tectonics?

• The formation of new oceans.

• The creation of uniform land surfaces.

• The absence of earthquakes.

• The stability of Earth's surface.

How do plate tectonics contribute to volcanic eruptions?

• By preventing magma from reaching the surface.

• By allowing magma to escape through cracks in the crust.

• By cooling the Earth's core.

• By stopping the movement of crustal plates.

Explain how the rock cycle is related to plate tectonics.

• Plate tectonics has no effect on the rock cycle.

• Plate tectonics drives the formation and destruction of rocks.

• Plate tectonics only affects sedimentary rocks.

• Plate tectonics prevents the recycling of rocks.
