Amplify Plate Motion Chapter 1

Front

What is a plate boundary?

Back

The place along which two plates meet.

Front

What is Earth's outer layer made of?

Back

Earth's outer layer is made up of hard, solid rock.

Front

What are the pieces that make up Earth's surface called?

Back

Tectonic Plates.

Front

What causes earthquakes?

Back

Earthquakes are caused by plate motion.

Front

What do geologists look for in geologic events to understand Earth's outer layer?

Back

Patterns.

Front

What are the three main types of plate boundaries?

Back

Divergent, Convergent, and Transform boundaries.

Front

What happens at a divergent plate boundary?

Back

Plates move apart, creating new crust as magma rises to the surface.

Front

What is a convergent plate boundary?

Back

A boundary where two plates collide, often causing one plate to be forced beneath the other.

Front

What is a transform plate boundary?

Back

A boundary where two plates slide past each other horizontally.

Front

How do tectonic plates move?

Back

Tectonic plates move due to convection currents in the mantle.
