Plate Tectonics

5. Most are underwater and form submarine mountain ranges called oceanic spreading ridges.
6. Earthquakes and Tsunamis.
8. Movement of magma in the mantle causing the crust to move/break making earthquakes.
10. Earthquakes occur as new crust is created and other crust is pushed out.
15. Linear valleys or broken stream beds.
16. What is one piece of evidence of the CD?
17. What is the first piece of evidence?
18. What is a third piece of evidence of CD?
19. Who came up with the idea of SFS
22. What is a third piece of evidence?

1. Water displaced by an earthquake.
2. Two plates come together or converge.
3. What did scientists use to discover it.
4. Trenches, volcanoes, and mountains
7. Weak point in the crust where molten material or magma, comes to the surface.
9. What is a second piece of evidence of CD?
11. A deep valley that forms where two plates move apart.
12. Two plates that move apart or diverge.
13. Two plates slip past each other moving in the opposite direction.
14. Earthquakes, large lateral displacement of rock, and a broad zone of crustal deformation.
17. What is a second piece of evidence?
20. Shaking/Trembling that results from the movement of rock beneath the Earth's surface.
21. Who came up with the idea of the CD?
