  6. 6) What U.S. State is in the middle of the ring of fire? Hawaii

  7. 7) How is an earthquake produced? With the sudden movement of the ground caused by the release of energy when the rocks move along a fault.

  8. 8) Label the parts in the earthquake picture.

  9. 9) What is a fault? A break in the rock where movement occurs.

  10. 10) What is the epicenter of an earthquake? A point on the Earth’s surface where the Earthquake is first felt

  11. 11) What is the focus of the earthquake? Where the first movement occurs in the Earth’s Crust

  12. 12) What piece of equipment can measure seismic waves? A Seismograph

  13. 13) The area in the picture where no seismic waves occur after the earthquake is called the: Shadow Zone

  14. 14) Label the diagrams below.

  15. 15) Identify each wave as either an S-Wave or a P-wave P-wave S-wave

  16. 16) Speed of wave A: Speed of wave B: Fastest 2nd Fastest 17) A Movement: B Movement: Back and Forth Perpendicular 18) A moves through: B moves through: Solid, Liquid, Gas Solid

  17. 19) What does the Richter Scale tells about an earthquake? Magnitude; Strength

  18. 20) What does the Mercalli scale tell us about an earthquake? Intensity: the amount of damage that occurred

  19. 21) The damage an earthquake does is called: Its Intensity – Mercalli Scale

  20. 22) The strength of an earthquake is called its: Magnitude – Richter Scale

  21. 23) What is a tsunami? A giant wave that forms after a volcanic eruption, submarine earthquake or landslide.

  22. 24) Where is magma found? Below ground

  23. 25) Where would lava be found? Above Ground
