Tectonic Hazards and Plate Tectonics Quiz

What is a tectonic hazard?

• The layer of the Earth that we live on.

• A section of the Earth’s crust.

• A natural hazard caused by movement of tectonic plates including volcanoes and earthquakes.

• The idea that the Earth’s continents were once joined together.

What is a tectonic plate?

• The layer underneath the crust.

• A section of the Earth’s crust.

• The rigid outer part of the earth.

• Circular pockets of heat that move in the mantle.

Where do two plates meet?

• Plate Margin

• Asthenosphere

• Lithosphere

• Convection Currents

What is the crust?

• The layer of the Earth that we live on.

• The layer underneath the crust.

• The semi-solid part of the mantle.

• The idea that the Earth’s continents were once joined together.

What is the mantle?

• Circular pockets of heat that move in the mantle.

• A section of the Earth’s crust.

• The rigid outer part of the earth.

• The layer underneath the crust.

What is the lithosphere?

• The rigid outer part of the earth, consisting of the crust and upper mantle.

• The semi-solid part of the mantle below the lithosphere.

• The idea that the Earth’s continents were once joined together.

• A scientific theory about the movement of Earth's lithosphere.

What is the asthenosphere?

• The layer of the Earth that we live on.

• The rigid outer part of the earth.

• Semi-solid part of the mantle below the lithosphere.

• A section of the Earth’s crust.

What are convection currents?

• Circular pockets of heat that move in the mantle and cause plates to move.

• The idea that the Earth’s continents were once joined together.

• The weight of the denser plate sinking into the mantle.

• The increasing weight of the ridge pushing the plates apart.

What is slab-pull?

• Circular pockets of heat that move in the mantle.

• The idea that the Earth’s continents were once joined together.

• The weight of the denser plate sinking into the mantle at ocean trenches pulls the rest of the plate along.

• A scientific theory about the movement of Earth's lithosphere.

What is ridge-push?

• The idea that as the oceanic ridges build up the increasing weight of the ridge pushes the plates apart.

• The weight of the denser plate sinking into the mantle.

• Circular pockets of heat that move in the mantle.

• A section of the Earth’s crust.
