Explanation / Answer

1. Continental drift theory says that continents move and drift.

2. Pangaea is the massive and single piece continent for more than 245 million years.

3. Mid oceanic ridges are the series of undersea ridges.

4. Theory of plate tectonics proposes the movement of plates on earth.

5. Plate boundary is where the plates actually meet.

6. Convergent boundary is where the plates collide to form mountains.

7. Subduction is the process in which the plate goes under another plate.

8. Ring of fire is where numerous earth quakes and volcanic activity takes place.

9. Divergent boundary is where the two plates divide and move away.

10. San Andreas fault is the transform fault.
