Amplify Unit 2 Plate Motion - Review

Front

What is a Mid-Ocean Ridge?

Back

A Mid-Ocean Ridge is an underwater mountain range formed by plate tectonics, where tectonic plates are moving apart.

Front

What type of plate movement forms a mid-ocean ridge?

Back

Divergent plate movement.

Front

What do patterns on a geological map indicate about volcanic activity and earthquakes?

Back

Volcanic activity and earthquakes happened in similar areas.

Front

What is Pangaea?

Back

Pangaea is the name of the super-continent that existed millions of years ago.

Front

Describe the state of Earth's plates and mantle.

Back

Earth's plates are hard solid material, while Earth's mantle is soft solid material.

Front

What is the theory of continental drift?

Back

The theory of continental drift suggests that continents have moved over geological time and were once joined together.

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 happens at a convergent plate boundary?

Back

At a convergent plate boundary, two tectonic plates collide, which can cause mountains to form or lead to subduction.

Front

What is subduction?

Back

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

Front

What is a transform plate boundary?

Back

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