What is the continental crust?

• A thin, solid layer of rock under the oceans

• A thick, solid layer of rock that makes up the land we walk on

• A layer of hot, semi-liquid rock beneath the Earth's crust

• A process where oceanic crust is recycled into the mantle

What is the oceanic crust?

• A thick, solid layer of rock that makes up the land we walk on

• A thin, solid layer of rock found under the oceans

• A layer of hot, semi-liquid rock beneath the Earth's crust

• A process where oceanic crust is recycled into the mantle

What is the mantle?

• A thick, solid layer of rock that makes up the land we walk on

• A thin, solid layer of rock found under the oceans

• A thick layer of hot, semi-liquid rock beneath the Earth's crust

• A process where oceanic crust is recycled into the mantle

What occurs at a destructive boundary?

• Two pieces of the Earth's crust move apart

• Two pieces of the Earth's crust slide past each other

• Two pieces of the Earth's crust collide and one is pushed into the mantle

• Oceanic crust is recycled into the Earth's mantle

What occurs at a constructive boundary?

• Two pieces of the Earth's crust move apart and new crust is made

• Two pieces of the Earth's crust slide past each other

• Two pieces of the Earth's crust collide and one is pushed into the mantle

• Oceanic crust is recycled into the Earth's mantle

What occurs at a conservative boundary?

• Two pieces of the Earth's crust move apart and new crust is made

• Two pieces of the Earth's crust slide past each other

• Two pieces of the Earth's crust collide and one is pushed into the mantle

• Oceanic crust is recycled into the Earth's mantle

What is subduction?

• A process where two pieces of the Earth's crust move apart

• A process where two pieces of the Earth's crust slide past each other

• A process where oceanic crust is recycled into the Earth's mantle

• A process where two pieces of the Earth's crust collide

What does the term "seismic" refer to?

• The creation of new ocean floor

• The recycling of oceanic crust into the mantle

• The shaking of the ground during an earthquake

• The movement of tectonic plates

What is a composite volcano?

• A very large volcano with gentle slopes

• A smaller volcano with steep slopes and very sticky lava

• A super-hot, fast-moving avalanche of gas, ash, and rock

• A process where oceanic crust is recycled into the Earth's mantle

What is a shield volcano?

• A very large volcano with gentle slopes and very runny lava

• A smaller volcano with steep slopes and very sticky lava

• A super-hot, fast-moving avalanche of gas, ash, and rock

• A process where oceanic crust is recycled into the Earth's mantle
