Plate Motion Ch. 3 TEST

Front

What is Plate Tectonics?

Back

The theory that explains the movement of the Earth's plates and how they interact with each other.

Front

Who proposed the theory of continental drift?

Back

Alfred Wegener.

Front

What is a divergent plate boundary?

Back

A boundary where two tectonic plates move away from each other, often creating new crust.

Front

What landform is typically found at divergent plate boundaries?

Back

Mid Ocean Ridge.

Front

What is a convergent plate boundary?

Back

A boundary where two tectonic plates collide, leading to one plate being forced below the other.

Front

What is a transform plate boundary?

Back

A boundary where two tectonic plates slide past each other horizontally.

Front

What evidence did Wegener use to support his theory?

Back

Fossil evidence, geological similarities, and the fit of the continents.

Front

What is the significance of the Mid Ocean Ridge?

Back

It is a major underwater mountain range formed by plate tectonics and is a site of seafloor spreading.

Front

What is subduction?

Back

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

Front

What are tectonic plates?

Back

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