Plate Tectonics

1. The strong, lower part of the mantle between the Asthenosphere and the outer core.
6. The soft plastic-like layer of the mantle on which the tectonic plates move.
8. Solid outer layer that consists of the crust and the rigid upper part of the mantle.
11. A block of lithosphere that consists of the crust and the rigid, outermost part of the mantle.
13. The nature of something ´ s ingredients or constituents
14. The hypothesis that states the continents once formed a single landmass, broke up, and drifted to their present location.
15. The center of the Earth, like a ball of hot metal and it is mostly iron and nickel.
17. The middle layer of the Earth which is the largest layer.
18. Tectonic plates move apart together and form depending on the types.
19. Properties that involve a reaction to an applied load strength, ductility, hardness, impact resistance, and toughness.

2. The process by which new oceanic lithosphere forms as magma rises toward the surface and solidifies.
3. The only liquid layer of the planet.
4. The theory that explains how large pieces of the Earth ´ s crust move and change shape.
5. Stress that occurs when the forces act to squeeze an object.
7. The sinking of regions of the Earth ´ s crust to lower elevations.
9. Tectonic plates slide past each other resulting in earthquakes.
10. A break in a body of rock along which one block slides relative to another.
12. The inner most layer of the Earth.
15. The thin,solid, rigid outermost layer of the Earth.
16. Tectonic plates collide together and from various land forms depending on the types that converge.
