Question 5 (1 point)
Which of these statements is true about the theory of plate tectonics and the theory of continental drift?

Question 5 options:

The theory of plate tectonics does not explain how continental movements could occur.

The theory of plate tectonics proves the theory of continental drift completely wrong.



The theory of plate tectonics tells exactly where the continents were before Pangaea divided.



The theory of plate tectonics gives the method by which continents can move as part of plates.
