Tectonic Plates

1. this action often leads to a volcano, an oceanic plate force beneath a continental one
6. the bending of rock layers due to the stress of the earth’s crust
8. long narrow depression that forms on the seafloor at the boundary of tectonic plates, when one is being pushed below another.
11. One of the huge sections which make up the Earth's crust.
15. “Father of Plate tectonics.”
16. where crust is destroyed as one plate dives under another.
17. the plate located just underneath South Africa
18. A vent (opening) in the surface of the Earth through which magma erupts;
19. a break in the earth’s crust due to the tectonic forces
20. Shaking of the Earth caused by a sudden movement of rock beneath its surface.

2. where new crust is generated as the plates pull away from each other.
3. The theory that the earth was originally one land mass.
4. relating to the structure of the earth's crust and the large-scale processes which take place within it.
5. this is the layer that allows the tectonic plates to move
7. the earth’s layer the forms the tectonic plates
9. where crust is neither produced nor destroyed as the plates slide horizontally past each other, cause of earthquakes.
10. layer that the tectonic plates slide on
12. the area where on tectonic plate gets forced under another
13. way to describe the tremor of the earth that is caused by earthquakes.
14. Loa the biggest volcano in the world
