plate motion

6. view or drawing that shows what the inside of something looks like after a cut has been made across it.
9. tectonic boundary where two plates are moving toward each other.
10. plate:massive slab of solid Plate:geology the study of the structure of the earth's crust and mantle with reference to the theory that the earth's lithosphere is divided into large rigid blocks.
13. an oceanic plate runs into a continental plate and slides beneath itrock made up of Earth's lithosphere (crust and upper mantle)
14. all the Earth.
16. used to record the motion of the ground during an earthquake.
18. measure of the size of an earthquake based on observation of the effects of the shock at the earth's surface.
19. mostly-solid bulk of Earth's interior.
20. where two plates move away from each other
21. the place inside Earth's crust where an earthquake originates.
22. on the surface of the Earth that is directly above the underground point (called the focus) where fault rupture commences, producing an earthquake.

1. super massive wave
2. or zone of fractures between two blocks of rock.
3. boundary: A tectonic boundary where two plates are moving toward each other.
4. a measurement of earthquakes.
5. wave:shock waves in solid rock generated by earthquakes or underground explosions.
7. drift:the movement of continents resulting from the motion of tectonic plates
8. large continuous mass of land conventionally regarded as a collective region.
11. type of fault in which two tectonic plates slide past one another.
12. extremely hot center of Earth, another planet, or a star
15. outermost shell of a terrestrial planet.
17. release of energy through the earth's crust in the form of seismic waves.
