Plate Boundaries

Front

What makes the plate tectonics move?

Back

Convection currents in the mantle cause the movement of tectonic plates.

Front

Who proposed the Plate Tectonics Theory?

Back

Harry Hess proposed the Plate Tectonics Theory.

Front

What type of evidence was helpful in proving the Continental Drift theory?

Back

Fossil evidence, continental fit, glacial evidence, and landform and rock layers were key in proving the Continental Drift theory.

Front

What is a transform boundary?

Back

A transform boundary is where two tectonic plates slide past each other.

Front

What is a plate boundary?

Back

A plate boundary is the region where two tectonic plates meet.

Front

What is a divergent boundary?

Back

A divergent boundary is where two tectonic plates move away from each other.

Front

What is a convergent boundary?

Back

A convergent boundary is where two tectonic plates collide.

Front

What is subduction?

Back

Subduction is the process where one tectonic plate moves under another and sinks into the mantle.

Front

What are tectonic plates?

Back

Tectonic plates are large sections of the Earth's lithosphere that move and interact with each other.

Front

What is the lithosphere?

Back

The lithosphere is the rigid outer layer of the Earth, consisting of the crust and upper mantle.
