Tectonics

3. The point on the earth's surface vertically above the hypocenter (or focus), point in the crust where a seismic rupture begins
4. go down below the surface of something, especially of a liquid; become submerged.
5. The act, state or process of changing, such as in form or structure; the conversion from one form to another
7. the term for how heavy an object is for its size
8. Trench a crescent-shaped scar in Earth's crust that measures more than 1,500 miles (2,550 kilometers) long and 43 miles (69 kilometers) wide on average
9. the solid, outer part of the Earth.
12. the moving of something from its original
15. a long, narrow, elevated landform, structural feature, or a combination of both separated from the surrounding terrain by steep sides
16. the mostly solid bulk of Earth's interior
17. the liquid or molten rock found beneath Earth's surface
19. The outer shell of the planet
20. fracture or zone of fractures between two blocks of rock

1. the amount of space that a substance or object occupies, or that is enclosed within a container, especially when great.
2. an elastic wave in the earth produced by an earthquake or other means.
6. instruments used to record the motion of the ground during an earthquake
10. the innermost layer of the Earth and is located at the direct center of the Earth
11. pieces of rock that have been transported from their original location by natural processes like glaciers, rivers, or landslides
13. a point where two tectonic plates are moving apart from each other, causing new crust to form as magma rises from the Earth's mantle to fill the gap between the plates
14. measures the energy released at the source of the earthquake
18. the sudden release of strain energy in the Earth's crust, resulting in waves of shaking that radiate outwards from the earthquake source
