Plate Tectonics

5. The point on the Earth's surface directly above the focus
6. Isolated place away from plate boundaries, where a lot of hot magma is being created
11. Process of continents breaking up, subsiding and letting the sea in
13. hot fluid or semi-fluid material below or within the earth's crust
14. New crust being formed at the ocean ridges and spreading outwards
15. Chain of islands formed at the edges of colliding tectonic plates where on plate subducts
16. is a continental transform fault that extends roughly 1,200 kilometers through California
17. The place below the ground where an earthquake starts

1. When continents separate and drift
2. a major area in the basin of the Pacific Ocean where many earthquakes and volcanic eruptions occur.
3. An instrument for detecting the seismic waves from an earthquake
4. is a fast-moving current of deadly hot gas and volcanic matter
7. A huge wave in the ocean caused by an undersea earthquake
8. Areas where one crust is sinking below another crust
9. Boundary where plates are colliding
10. a mountain or hill, typically conical, having a crater or vent through which lava, rock fragments, hot vapour, and gas are or have been erupted from the earth's crust.
12. a supercontinent that existed during the late Paleozoic and early Mesozoic eras
16. basaltic lava rock ejected as fragments from a volcano, typically with a frothy texture
