Plate Tectonics Quiz

Which best explains what a plate is?

• a piece of asthenosphere moving over the lithosphere

• a piece of lithospheres floating over the asthenosphere

• location of only volcanoes causing new floor or continental formation

• continental land that moves over the asthenosphere

Which of the following best explains the plate tectonic theory?

• the slipping of faults to cause earthquakes

• weathering, erosion, and deposition of sediments to develop continents

• movement of magma in the asthenosphere

• the interaction and movement of plates

Where do most earthquakes and volcanoes occur?

• In the middle of tectonic plates

• At plate boundaries

• In desert regions

• In polar areas

What aligns with the magnetic field in ocean floor rocks?

• Copper

• Iron

• Gold

• Silver

What is the significance of the mid-ocean ridge in ocean floor age?

• It is where the oldest ocean floor is found

• It is where the youngest ocean floor is found

• It is where the ocean floor is the deepest

• It is where the ocean floor is the shallowest
