Earth's Changes and Plate Tectonics Flashcard Review

Front

What is the principle of superposition in geology?

Back

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

Front

Example of fossil evidence that supports the idea that Earth has changed over time.

Back

The presence of similar fossils in different continents.

Front

How does the movement of tectonic plates cause earthquakes?

Back

By the collision and sliding of plates against each other.

Front

How does the theory of plate tectonics explain the formation of ocean basins?

Back

Ocean basins form when tectonic plates move apart, creating space for water to fill.

Front

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

Back

By observing that the oldest layers are at the bottom and the youngest are at the top.

Front

What role do hot spots play in volcanic activity?

Back

Hot spots are areas where magma from deep within the mantle melts through the crust.

Front

Analyze how fossil evidence supports the theory of continental drift.

Back

Similar fossils found on different continents suggest they were once connected.

Front

What is the significance of plate tectonics in the formation of mountains?

Back

Mountains form when tectonic plates collide and push the Earth's crust upwards.

Front

Evaluate the impact of supervolcanoes on Earth's geological history.

Back

Supervolcanoes can cause massive eruptions that alter climate and geography.

Front

How does the concept of plate tectonics explain the occurrence of volcanic eruptions?

Back

Volcanic eruptions occur when tectonic plates move apart or collide, allowing magma to reach the surface.
