Amplify Plate Motion - Chapter 2

Front

What is the Earth's outer layer made of underneath soil and water?

Back

Underneath both the soil and the ocean, Earth’s outer layer is made of hard, solid rock.

Front

What does 'converge' mean in the context of plate motion?

Back

To move towards each other.

Front

What happens at a divergent plate boundary?

Back

The plates will separate, and magma from the mantle will create new rock on the edges of the plates over time.

Front

What occurs when two tectonic plates move apart?

Back

Soft, solid rock from underneath the plates rises and hardens, adding new solid rock.

Front

Where will the team find hard, solid rock when drilling underground?

Back

They will find hard, solid rock below both sites.

Front

What is a convergent plate boundary?

Back

A boundary where plates collide, and one plate may subduct into the mantle.

Front

What is a divergent plate boundary?

Back

A boundary where plates move apart, allowing magma to rise and create new rock.

Front

What is subduction?

Back

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

Front

What is the mantle?

Back

The layer of the Earth located between the crust and the core, composed of semi-solid rock.

Front

What is magma?

Back

Molten rock located beneath the Earth's surface.
