28
1. Explain the Elastic Rebound Theory
volcano Sea Floor Spreading Ocean Land LAVA If land is lifted too high, it can crack resulting in a 9.0 earthquake
29
1. Explain the Elastic Rebound Theory
volcano Sea Floor Spreading Ocean Land Subduction Zone LAVA There are Many earthquakes In a subduction zone
30
1. Explain the Elastic Rebound Theory
volcano Sea Floor Spreading Ocean Land Subduction Zone LAVA There are 1 dozen or so plates that make up the surface of the Earth. Each of these plates are floating on the mantle. They Are bumping and grinding on each other creating earthquakes.
31
Explain how a seismograph works.
Earthquakes generate seismic waves which can be detected with a sensitive instrument called a seismograph. Advances in seismograph technology have increased our understanding of both earthquakes and the Earth itself. Perhaps the earliest seismograph was invented in China A.D. 136 by a m an named Choko. Can you tell how one Works?
32
3. Explain paths of Seismic Waves.
P waves - creates the big band sound, fastest wave first to travel and is a compression wave. S waves - are transverse waves with an up and down motion. L waves - most destructive waves are last to hit and result in a rolling motion.
33
4. How do you locate an epicenter?
You must have three different seismographs at three different Locations - then you can pinpoint the different times each picked Up the earthquake wave. You will do this in a lab.

7. How is a tsunami generated?
Underwater earthquakes that jolt the water. As it travels it gains height by the beach. 8. Name some places in the US that have seen the most quakes - Why do you think these are high risk zones? California up to Washington are part of the ring of fire. This is where San Andreas Fault is and the Cascade Mountains

9. List many ways one can prepare for an earthquake
Have tools handy to turn off gas Extra water and food Ready made shelters Extra medication Have arraigned a place to call
