Quiz: Plate Tectonics

Which of the following best describes the concept of continental drift?

• The movement of oceanic plates away from mid-ocean ridges.

• The gradual movement of continents across the Earth's surface over geological time.

• The formation of mountains due to the collision of tectonic plates.

• The sinking of oceanic plates into the mantle at subduction zones.

What is the primary cause of sea floor spreading?

• The gravitational pull of the moon.

• The upwelling of magma at mid-ocean ridges.

• The erosion of oceanic crust by ocean currents.

• The collision of tectonic plates.

Which type of plate boundary is most commonly associated with the creation of new oceanic crust?

• Convergent boundary

• Divergent boundary

• Transform boundary

• Subduction zone

Paleomagnetism provides evidence for which geological process?

• Earthquakes

• Volcanic eruptions

• Plate tectonics

• Weathering and erosion

What is the significance of magnetic stripes found on the ocean floor?

• They indicate the presence of underwater volcanoes.

• They show the direction of ocean currents.

• They provide evidence for sea floor spreading.

• They mark the boundaries of tectonic plates.

Which of the following statements is true about transform plate boundaries?

• They are locations where plates move away from each other.

• They are characterized by the creation of new crust.

• They are sites where plates slide past each other horizontally.

• They are areas where one plate is forced under another.

How does the age of oceanic crust change as you move away from a mid-ocean ridge?

• It becomes younger.

• It remains the same.

• It becomes older.

• It fluctuates randomly.

What role does convection in the mantle play in plate tectonics?

• It causes the plates to sink into the mantle.

• It drives the movement of tectonic plates.

• It creates earthquakes at plate boundaries.

• It forms mountains at convergent boundaries.

Which of the following is a result of the collision of two continental plates?

• Formation of ocean trenches

• Creation of mid-ocean ridges

• Formation of mountain ranges

• Development of volcanic islands

What evidence supports the theory of continental drift?

• Similar rock formations found on different continents

• The presence of deep ocean trenches

• The occurrence of earthquakes

• The distribution of ocean currents
