Plate Tectonics Quiz

What has caused the continents to move over time?

• Volcanic eruptions

• Earthquakes

• Movement of Earth's plates

• Tidal waves

Why are the youngest rocks found at the plate boundaries?

• They are remnants of ancient civilizations

• They are the result of erosion

• They are formed by volcanic activity

• They are pushed there by older rocks

What do we call the underwater mountain range that extends down the center of the Atlantic Ocean and through many other parts of the ocean?

• Mid-Atlantic Ridge

• Pacific Ring of Fire

• Himalayan Mountains

• Andes Mountains

At divergent plate boundaries, the plates are moving away from each other. (True/False)

• True

• False

As new oceanic rock is created at the mid-ocean ridges, older rock is pushed to the sides and the plates pull apart. This is known as sea floor spreading. (True/False)

• False

• True

As the plates move, the continents on them move as well. (True/False)

• True

• False

Which location did the rock with the oldest age most likely come from?

• Mid-Atlantic Ridge

• Aleutian Islands

• Subduction Zone

• Mariana Trench

What is happening to the overall size of the Atlantic and the Pacific Oceans?

• They are getting bigger

• They are getting smaller

• They are staying the same

• They are disappearing

What occurs at subduction zones?

• Creation of volcanic islands

• Erosion of oceanic rock

• Formation of new oceanic crust

• Sinking of a dense tectonic plate beneath a less dense one

Where does crust get destroyed?

• Convergent plate boundaries

• Mid-ocean ridges

• Subduction zones

• Divergent plate boundaries
