Front

What is the mantle made of?

Back

The mantle is made of molten or melted rock.

Front

What is the hot, liquid rock below the Earth's crust called?

Back

The hot, liquid rock below the Earth's crust is called magma.

Front

What is the crust made of?

Back

The crust is made of a thin layer of solid rock.

Front

What is the top layer of the Earth called?

Back

The top layer of the Earth is called the crust.

Front

The large chunks that the crust is broken up into are called ________________.

Back

The large chunks that the crust is broken up into are called tectonic plates.

Front

What are tectonic plates?

Back

Tectonic plates are large pieces 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 the upper mantle.

Front

What is the asthenosphere?

Back

The asthenosphere is the semi-fluid layer of the mantle beneath the lithosphere that allows tectonic plates to move.

Front

What is subduction?

Back

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

Front

What is a divergent boundary?

Back

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