? The difference in arrival times between P-waves & S-waves is called ........?........ * What is the name of a very famous California fault? Answer: 99% quakes are at plate boundaries (*San Andreas fault) Answer: lag time is the difference between P-wave & S-wave arrival. Each number up the Richter Scale represents an earthquake that is ..?.. times stronger than the number before! ? * Which seismic wave cannot pass thru liquids ? Answer: P-waves pass thru solids and liquids (* S-waves pass only thru solids. They cannot pass thru liquids) Answer: each step is 10 time stronger (*4 is 100 times stronger) 90W ? What is the name of the seismic wave that travels at 6.4 km/hr and arrives first? 30S Answer: P-wave ? 0 . #1 60W Where is the epicenter? . #2 . #3 30S 30W 0 ? * Which recording station is at 83W long 0 lat ? Answer: epicenter is at 70W long 16S lat (* station #1 is at 83W 0) #1 * With one recording station epicenter location is ......?...... Which layer of Earth’s interior is thought to be liquid? Answer: S-wave #2 ? Answer: outer core is liquid (S-waves don’t go thru it) #3 . #2 90W ? 0 How many recording stations are required to pinpoint the epicenter location? . #3 30W Answer: 3 stations to pinpoint epicenter (* somewhere on the circle) ? What are the names of the numbered layers of Earth’s interior? 60W #1 0 . What is the name of the seismic wave that travels at 3.2 km/hr and arrives second? ? Which seismic wave can pass thru solids or liquids? * A Richter value “4” quake is ...?... times stronger than a Richter value “2” quake. #4 ? Where do 99% of all earthquakes occur? Answer: #1crust (or lithosphere), #2 mantle, #3 outer core, #4 inner core
