Continental Drift Review

Front

What is Pangea?

Back

Pangea was a supercontinent that existed during the late Paleozoic and early Mesozoic eras, where all continents were joined together.

Front

What does the theory of continental drift state?

Back

The theory of continental drift states that the continents were once joined in a supercontinent and have moved over time.

Front

What are the three types of evidence that support Alfred Wegener's Theory of Continental Drift?

Back

Fossils, Land forms, and Climate.

Front

Who is credited with developing the theory of continental drift?

Back

Alfred Wegener.

Front

What is plate tectonics?

Back

Plate tectonics is the scientific theory that describes the large-scale movements of Earth's lithosphere, which is divided into tectonic plates.

Front

What is the significance of matching fossils found on different continents?

Back

Matching fossils provide evidence that continents were once connected, supporting the theory of continental drift.

Front

What are glacial striations?

Back

Glacial striations are scratches or grooves left on bedrock by the movement of glaciers, indicating past glacial activity.

Front

How do mountain ranges support the theory of continental drift?

Back

Mountain ranges with the same rock type and age lining up across oceans suggest that continents were once joined.

Front

What role does climate evidence play in continental drift?

Back

Climate evidence, such as tropical plant fossils found in cold regions, indicates that continents have moved to different climate zones.

Front

What is the lithosphere?

Back

The lithosphere is the rigid outer layer of the Earth, consisting of the crust and upper mantle, which is broken into tectonic plates.
