Science
Across
- 3. Areas where one plate is forced beneath another.
- 5. A mountain that opens downward to a reservoir of molten rock underneath the surface of Earth.
- 7. A Japanese word for tidal wave or big wave in the port.
- 9. The area where the fault occurs.
- 12. A type of earthquake that is caused by the injection or withdrawal of magma.
- 14. The point on Earth's surface directly above the focus.
- 15. The world's largest and strongest earthquake belt.
- 16. A sudden and violent shifting of massive plates underneath Earth's surface.
- 18. These are the first waves to be recorded in a seismic station.
- 20. The scientific study of earthquake and the propagation of elastic waves through Earth.
- 23. An earthquake that results from detonation of chemicals or nuclear devices.
- 24. Molten rock.
- 26. Also caled ground roll, cause rock particles to move upward up, backward, and own in a path that contains direction of the wave travel.
- 27. A scientist who studies seismic waves.a
- 29. A crack across which the rocks have been offset first.
- 31. A type of earthquake that occers when Earth's plate shift around.
- 32. Are areas or columns where heat or rocks in the mantle are rising toward Earth's surface.
Down
- 1. A fault which the hanging wall moves down relative to the footwall.
- 2. Occurs when when matter such as magma circulates within Earth.
- 4. Refers to a large wave that moves up and down instead of forward.
- 6. A type of earthquake that are located underground and in mines.
- 8. The roughness or harshness along the fault.
- 10. Processes and phenomena associated with the surfical discharge of molten rock
- 11. A fault which two blocks of crust slide past each other.
- 13. These waves cause the most damage to buildings and other structures.
- 17. Refers to the block of crust above the fault.
- 19. Waves that travel below the surface of Earth.
- 21. Where the earthquake originates from.
- 22. The size of the earthquake.
- 25. Also called thrust fault, a fault in which the hanging wall moves up.
- 28. Locations on Earth's surface that has experienced active volcanic activites for a long period of time.
- 30. Is the block of crust below the fault.
