Across
- 1. Zone- area where one plate is being pulled under the edge of another.
- 4. A high, large mass of earth and rock that rises above the earth's surface with steep or sloping sides.
- 8. - two plates slide past each other.
- 10. Hard and rigid, it's the earth's outermost and thinnest layer
- 13. An extremely hot, solid sphere of mostly iron and nickel at the center of the earth
- 14. Subdivided into two regions, upper and lower, this dense layer made of hot, semisolid rock is located directly below the crust
- 17. earth's continents were once joined together in one large mass
- 18. noticed that the coastlines of Africa and South America looked like they might fit together
- 19. The sudden movement is what we feel as the shaking and trembling

Down
- 2. The earth's crust found underneath the oceans.
- 3. - two plates that are moving apart from each other.
- 5. only liquid layer of the earth – a sea of mostly iron and nickel.
- 6. The earth's crust that makes up the continents.
- 7. A vent in the earth's surface through which magma and gases erupt.
- 9. A hot, semiliquid zone on which the tectonic plates float.
- 11. A arc-shaped chain of volcanoes formed above a subduction zone.
- 12. Rigid outer layer of the earth broken up into the tectonic plates.
- 15. - two plates are pushing toward each other
- 16. a crack or fracture in the earth's crust that is associated with this movement
