What drives the movement of tectonic plates according to the theory of plate tectonics?

• Solar energy

• Convection currents in the mantle

• Magnetic fields

• Gravity

What type of boundary occurs where two plates collide?

• Convergent boundary

• Isolated boundary

• Transform boundary

• Divergent boundary

Which of the following is a result of plate tectonics?

• Mountain formation

• Volcanic eruptions

• Earthquakes

• All of the above

What happens at subduction zones?

• Plates move apart

• One plate slides under another

• Plates remain stationary

• Plates merge

What is the Ring of Fire known for?

• Earthquakes

• Both A and B

How does plate tectonics contribute to the rock cycle?

• By moving rocks

• Through erosion
