Plate Tectonics

4. remains of past life that is scattered throughout the continents which can prove the Continental Drift theory
5. when two plates with oceanic crust at their edges converge and the denser of the two plates sinks under the other
8. Wegener person who first discovered the Continental Drift theory
9. shaking of Earth due to transform plate boundaries
11. currents the most accepted theory on what makes the plates move
12. plate boundary two plates collide by sliding past each other
15. Earth 225 million years ago as one whole mass
18. Arc when some magma breaks through Earth's solid surface and forms a series of volcanoes and volcanic islands
19. Tectonics theory Theory that Earth's lithosphere is broken up into sections or pieces called plates and they cause major changes in Earth's surface

1. Puzzle the Continental Drift can be proven because the continents used to fit like a...
2. plate boundary two plates separate
3. plate boundary two plates collide
6. Warped ocean Basin if there is a continent near the two converging plates with oceanic crust, the crust at the margin of the continent may become bent down
7. trench the bending down of the subducting plate warps the crust, producing a long, steep, and narrow depression
10. spots major regions of volcanic activity in the interior parts of plates away from plate boundaries
13. plate convergence that results in the growth of young mountain ranges
14. high land features that form due to converging plate boundaries
15. the pieces Earth's lithosphere is broken up into are called...
16. ocean ridge a balsaltic mountain range at the bottom of the ocean that is composed mostly is volcanoes and lava flows
17. Wegener thought this separated the continents at first, but he was wrong
