Quiz on Plate Tectonics

What is a tectonic plate?

• A broken piece of Earth's crust that floats on top of the mantle

• A solid piece of Earth's mantle

• A layer of liquid rock beneath the crust

• A type of volcanic rock

Why do tectonic plates move?

• Because they are pushed by wind

• Because they float on the liquid mantle

• Because of gravitational pull from the moon

• Because they are attracted to each other

What type of plate movement occurs when plates move toward each other?

• Transform plate movement

• Static plate movement

• Convergent plate movement

• Divergent plate movement

What happens at a destructive plate boundary?

• New crust is formed

• Crust is destroyed due to collision

• Plates slide past each other

• No significant geological activity occurs

What is the process called when an oceanic plate sinks under a continental plate?

• Transform faulting

• Convergence

• Divergence

• Subduction

What is formed when two continental plates converge?

• Fold mountains

• Oceanic trenches

• Volcanic islands

• Mid-ocean ridges

What is the result of divergent plate movement?

• Formation of earthquakes

• Destruction of crust

• Formation of new crust

• Creation of oceanic trenches

What is the Mid-Atlantic Ridge?

• A mountain range formed by convergent plates

• A trench formed by subduction

• A type of volcanic island

• A ridge formed by divergent plate movement

What characterizes a conservative plate boundary?

• Plates move away from each other

• Plates slide past each other

• Destruction of crust

• Creation of new crust

What often occurs along transform plate boundaries?

• Mountain formation

• Subduction

• Earthquakes

• Volcanic eruptions
