Across
- 2. an instrument that measures and records details of earthquakes
- 3. repetitive layering in metamorphic rocks
- 4. energy radiated or transmitted in the form of rays, waves, or particles
- 6. tracing and measurement of a series or network of triangles in order to determine the distances and relative positions of points spread over a territory or region
- 8. not fluid from earth's crust
- 13. mudflow material that comes from a valcano
- 14. shear body waves that moves through the body of an object
- 17. ridge system situated in the middle of an ocean basin and marking the site of the upwelling of magma associated with seafloor spreading
- 18. vastness of something
- 19. two tectonic plates coming together
- 21. number scale that tells the magnitude of an earthquake
- 23. Waves type of body waves that is the first to show up in the seismograph from an earthquake
- 24. formed from cooling and solidifying of magma or lava
- 26. place where earthquake begins
Down
- 1. small solid particles that come from an erupted volcano
- 5. hot molten from an erupted volcano
- 6. tectonic plates that slide past each other
- 7. steep depressions in the deepest parts of the ocean where old ocean crust from one tectonic plate is pushed beneath another plate
- 9. record made by the seismograph
- 10. rock formed from deposition and solidification of sediment
- 11. rock formation formed from being broken
- 12. rock changed from heat and pressure
- 15. point on the earth's surface vertically above the focus of an earthquake
- 16. two tectonic plates moving away
- 20. movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.
- 22. process in which sediments, soil and rocks are added to a landform or land mass
- 25. giving energy through a medium without changing the medium
