*7.10A Earth's Changes Over Time Quiz

What is the principle of superposition in geology?

• The oldest layers of rock are on the top, and the youngest are on the bottom.

• The youngest layers of rock are on the top, and the oldest are on the bottom.

• All rock layers are the same age.

• Rock layers are formed in random order.

How does the movement of tectonic plates provide evidence for the changing Earth?

• Tectonic plates remain stationary, indicating a stable Earth.

• Tectonic plates move, causing earthquakes and volcanic activity, which reshape the Earth's surface.

• Tectonic plates dissolve over time, leaving no trace.

• Tectonic plates are only found in the ocean.

Explain how the concept of superposition can be used to determine the relative age of rock layers.

• By identifying the chemical composition of the rocks.

• By observing the sequence of rock layers, where the bottom layers are older than the top layers.

• By measuring the temperature of the rock layers.

• By counting the number of fossils in each layer.

Evaluate the impact of fossil evidence on our understanding of Earth's history and the theory of plate tectonics.

• Fossil evidence has no impact on our understanding of Earth's history.

• Fossil evidence supports the idea that continents have always been in their current positions.

• Fossil evidence provides crucial information that supports the theory of plate tectonics and shows how continents have moved over time.

• Fossil evidence only tells us about the types of organisms that existed in the past, not about Earth's history.
