There are 1 dozen or so plates that make up the surface of theEarth. Each of these plates are floating on the mantle. They Are bumping and grinding on each other creating earthquakes.

2. 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 oneWorks?

3. Explain paths of Seismic Waves.

1. P waves - creates the big band sound, fastest wave first to travel and is a compression wave.

2. S waves - are transverse waves with an up and down motion.

3. L waves - most destructive waves are last to hit and result in a rolling motion.

4. How do you locate an epicenter?

You must have three different seismographs at three differentLocations - then you can pinpoint the different times each pickedUp the earthquake wave. You will do this in a lab.

Plate tectonics is a theory that explains the plates that make up theCrust are floating and grinding against each other.

• 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
