Quiz on Continental Drift

What were Alfred Wegener’s 4 forms of evidence for continental drift?

• Fossil evidence, rock formations, climatic evidence, and the fit of the continents

• Fossil evidence, ocean currents, volcanic activity, and the fit of the continents

• Rock formations, ocean currents, climatic evidence, and volcanic activity

• Fossil evidence, rock formations, ocean currents, and volcanic activity

Which of the following explains how each of Wegener’s forms of evidence prove that continental drift is occurring?

• Fossil evidence

• Geological formations

• Climatic evidence

• All of the above

What is a mid ocean ridge?

• A deep underwater trench

• A mountain range under the ocean

• A large coral reef

• A type of ocean current

What is seafloor spreading?

• The process of new oceanic crust forming at mid-ocean ridges

• The movement of tectonic plates towards each other

• The erosion of the seafloor by ocean currents

• The accumulation of sediments on the ocean floor

How do the age of ocean rocks and magnetic striping prove seafloor spreading?

• They show that the ocean floor is older near the mid-ocean ridges.

• They indicate that the ocean floor is younger near the mid-ocean ridges.

• They demonstrate that the ocean floor is the same age throughout.

• They suggest that the ocean floor is older near the continents.

What is seafloor spreading?

What is the primary cause of tectonic plate movement?

• Gravitational pull from the moon

• Convection currents in the mantle

• Wind and ocean currents

• Solar radiation

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

• Convergent boundary

• Divergent boundary

• Transform boundary

• Subduction zone

What evidence supports the theory of seafloor spreading?

• Presence of similar fossils on different continents

• Symmetrical patterns of magnetic striping on either side of mid-ocean ridges

• Distribution of earthquakes along tectonic plate boundaries

• Formation of mountain ranges on land

What is the significance of the fit of the continents in supporting the theory of continental drift?

• It shows that continents were once connected and have drifted apart over time.

• It indicates that continents have always been in their current positions.

• It suggests that continents are moving towards each other.

• It proves that continents are stationary and do not move.
