Continental Drift and Pangaea Concepts

Front

What drives all plate movement in the Earth's mantle?

Back

Convection Currents

Front

Why did scientists initially reject Wegener's theory of Continental Drift?

Back

Because there was no explanation for how the continents move.

Front

What is the main cause of continental movement?

Back

Plate Tectonics

Front

What conclusion can be drawn from finding similar land animal fossils in eastern South America and western Africa?

Back

The two continents were once joined together as part of a larger continent.

Front

What does the Theory of Continental Drift state about Pangaea?

Back

Pangaea broke apart and the continents drifted away from each other.

Front

What are Convection Currents?

Back

Circular motions in the Earth's mantle that drive plate tectonics.

Front

What is Pangaea?

Back

A supercontinent that existed millions of years ago, where all continents were joined together.

Front

What is Plate Tectonics?

Back

The scientific theory that describes the large-scale movements of Earth's lithosphere.

Front

What evidence supports the theory of Continental Drift?

Back

Fossil similarities, geological formations, and the fit of continental coastlines.

Front

What is a Convergent Boundary?

Back

A tectonic plate boundary where two plates collide.
