Tectonics

4. Process in mantle that causes tectonic plates to move
6. Top of mantle on which the lithosphere (tectonic plates) move
8. The intensity of an earthquake is sometimes measured using this scale
9. Property that makes ocean plates sink
11. One of these is likely to happen at a strike-slip/transform boundary
12. The process that occurs as an ocean plate diverges and new rock is formed at the rift and ridge (two words)
16. P & S waves are these types of waves
17. The process of a plate sinking under another
18. He came up with the theory of Continental Drift
20. The "Ring of Fire" surrounds this tectonic plate
21. (T or F) Earthquakes are very predictable
23. Ocean that formed as Pangea separated
24. The number of seismic recordings needed to locate an earthquake's epicenter
26. Tall folded mountains occur at location "J" where continental plates converge
27. Hawaiian volcanoes from at one of these coming from a mantle plume (two words)
28. A deep-sea depression formed at subduction zones
29. Volcanic mountains that form at the center of a rift valley (usually in oceans)

1. Transform boundaries where plates slide past each other (two words)
2. The layer of the Earth that is made up of ocean and continental plates
3. Plate boundary where plates collide
5. A mammal-like reptile whose fossils are great evidence for continental drift
7. An instrument that records ground shaking
10. The point on the surface directly above the Earthquake's focus
13. You would find this type of volcano at divergent boundaries and hot spots
14. Violent stratovolcanoes can be found at location "L" where plate subduction happens
15. Plate boundary where plates divide
19. An opening formed as plats diverge (two words)
21. The point underground where the Earthquake's energy is released
22. Fissure volcanoes at a mid ocean rift and ridge occur at location "F"
25. Erosion from these match up on the Southern continents, providing climate evidence for cont.drift
