*7.10A Earth's Changes Over Time Flashcard

Front

What is the principle of superposition in geology?

Back

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

Front

What is an example of fossil evidence that supports the theory of plate tectonics?

Back

The presence of similar fossils on different continents.

Front

How do tectonic plates provide evidence for the changing Earth?

Back

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

Front

How can the concept of superposition be used to determine the relative age of rock layers?

Back

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

Front

What role does fossil evidence play in understanding Earth's history?

Back

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

Front

Define tectonic plates.

Back

Large sections of the Earth's lithosphere that move and interact with each other.

Front

What is the significance of earthquakes in geology?

Back

Earthquakes are caused by the movement of tectonic plates and can reshape the Earth's surface.

Front

What is a fossil?

Back

The preserved remains or traces of ancient organisms.

Front

Explain the theory of plate tectonics.

Back

The theory that the Earth's outer shell is divided into several plates that glide over the mantle.

Front

What evidence supports the theory of plate tectonics?

Back

Fossil evidence, geological formations, and the distribution of earthquakes and volcanoes.
