What type of boundary occurs when two tectonic plates collide?

Back

A convergent boundary is where two tectonic plates collide.

Front

What process adds new crust to the ocean floor along both sides of the mid-ocean ridge?

Back

Sea floor spreading is the process that adds new crust to the ocean floor.

Front

What is a plate boundary where both plates move away from each other?

Back

A divergent boundary is where both tectonic plates move away from each other.

Front

What is the process called when one tectonic plate is forced under another?

Back

Subduction is the process where one tectonic plate is forced under another.

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 is the Earth's outer layer called?

Back

The Earth's outer layer is called the lithosphere.

Front

What is an earthquake?

Back

An earthquake is the shaking of the Earth's surface caused by the sudden release of energy in the Earth's lithosphere.

Front

What is a volcano?

Back

A volcano is an opening in the Earth's crust through which molten rock, ash, and gases are expelled.
