The Earth and Tectonic Plates

1. A huge wave in the ocean caused by an Earthquake occurring on the seafloor
6. A deep valley in the Earth's crust that is much deeper than the area around it
7. Isolated places away from plate boundaries where a lot of hot magma is being created
8. Where plates are colliding with each other
9. Layer between the crust and the Earth's core
15. Made up of the crust and the upper-most mantle
16. A layer of 'plastic' semi-solid rock in the upper mantle
17. Hot liquid rock found under the Earth's surface

2. Where the crust is sinking down into the Earth
3. The place below ground where an Earthquake starts
4. The point on the Earth's surface directly above the focus of an Earthquake
5. The separating of the continents by drifting across the oceans
10. Type of boundary where plates are sliding next to each other but in opposite directions
11. The rapid movement of the ground, back and forth and up and down, as a result of tectonic plate movement
12. The process of continents breaking up, sinking and allowing the ocean in
13. Where plates are moving apart from each other in opposite directions
14. A place where extremely hot material from inside the Earth erupts at the surface
