Plate Tectonics Quiz | Plate Tectonics Online Test for Practice

31. This process of old crust being pulled down and remelted is called:

1. sea floor spreading
2. drifting
3. plate tectonics
4. subduction

32. Volcanoes form at this boundary as plates pull apart

1. convergent
2. transform
3. transform and convergent
4. divergent

33. What evidence did Wegener have for his theory of continental drift?

1. He had no evidence.
2. He knew that plant and animal fossils, as well as rock layers, matched on the two continents of Africa and South America.
3. He explained how continents moved apart.

34. What evidences do scientists use to support the continental drift theory?

1. rocks, fossils, air
2. rocks, fossils, climate
3. rocks, water, ice
4. rocks, fossils, human beings
