Plate Tectonics

3. Movement along strike slip faulting is not up and down, but
7. Outer, thinnest layer of the Earth
8. Molten rock from within the earth
9. Type of scale to describe an earthquake in terms of the amount of damage done
11. What the outer core of the Earth is composed of
13. Type of faulting is common at divergent plate boundaries
14. The theory of crustal movement was introduced in 1915 by Alfred
17. The upper,"plastic" mantle that is made up of partially melted material
19. Formed from a hot spot in the Earth's Crust
20. Type of plate boundary when two plates move opposite of each other

1. Type of scale to describe the amount of energy released by an earthquake
2. The continental crust is mostly made of
4. Type of plate boundary where an ocean trench will typically form
5. Layer found below the crust
6. The crust and outermost part of the mantle
10. Waves that ripple the surface of the Earth, causing most of the damage of an earthquake
12. Type of fault when two plates slide horizontally past each other
15. Type of plate boundary when two plates move together
16. In an earthquake the point on the surface directly above the focus
18. Rock layers get warped, or bent as a result of compression
