Where do convection currents occur in the Earth?

• Crust

• Core

• Mantle

• Lithosphere

What happens at a collision plate boundary?

• Plates move apart

• Plates move past each other

• Plates move towards each other and subduct

• Plates move towards each other and do not subduct

What forms when two plates move towards each other and crumple upwards?

• Faults

• Fold mountains

• Volcanoes

• Earthquakes

What is a crater?

• A type of volcano

• A fracture in the Earth's crust
