  3. What is the density of oceanic crust? About 3.0 g/cm3

  4. What is the depth, below the surface, of the outer core? 2800 - 2900 km

  5. What is the interior temperature at a depth of 3000 km in the earth? 5000oC

  6. What is the melting point of the rock at a depth of 4000 km? About 5500oC

  7. What is the name of the mountain range that lies on the western edge of the North American continent? The Cascades

  8. The 'plastic mantle' is also known as the.......... Asthenosphere

  9. What is the pressure at a depth of 3500 km below the surface of the earth? (GIVE UNITS!) About 2 million atmospheres

  10. In what state of matter is the rock at a depth of 3500 km in the earth? Liquid

  11. DAILY DOUBLE You may wager some or all of your money.

  12. What is the thickness of the outer core? 2200 - 2300 km

  13. What is the name of the interface between the crust and the plastic mantle? The MOHO

  14. How long does it take S waves to travel 3000 km? 10 minutes

  15. How far will P waves travel in 11 minutes 20 seconds? 8000 km

  16. A seismic station is 4000 km from the epicenter of an earthquake. How long after P waves arrive will the S waves arrive at the same station? 5 minutes 40 seconds

  17. It takes P waves 11 minutes and 20 seconds to travel from the epicenter of an earthquake to a seismic station. How long will it take S waves from the same earthquake to reach that seismic station? 20 minutes and 40 seconds

  18. S waves from an earthquake arrive at a seismic station at 2:15:20 PM. If the seismic station is located 2000 km from the epicenter, at what time did the earthquake occur? 2:08:00 PM

  19. What is the difference in arrival time between P and S waves at a distance of 2600 km from an epicenter? 4 minutes

  20. As the distance from an epicenter increases, the difference in arrival time between P & S waves ........... Increases

  21. An earthquake occurs at 3:30:00 AM. At what time will S waves arrive at a seismic station located 6500 km from the epicenter of the quake? 3:48:00 AM

  22. The difference in arrival times between P and S waves is 5 minutes and 20 seconds. How far from the epicenter is the seismic station located? 3600 km

  23. The difference in arrival times between P & S waves is 7 minutes and 20 seconds. If the P waves arrived at the station at 6:45:00 PM, at what time did the earthquake occur? 6:36:00 PM

  24. What term is used to describe the area in the diagram where "No waves" are recorded? Shadow Zone

  25. The location inside the earth where the earthquake actually occurs is called the........ Focus

  26. Why does zone 3 in the diagram receive P waves but no S waves? S waves cannot travel through the liquid outer core

  27. Which letter in the diagram represents the epicenter of the quake? Location C

  28. What kind of plate boundary is depicted in the diagram? A transform boundary

  29. FINAL JEOPARDY Wager all or some of your money! ?

  30. What was the time of origin of this earthquake? 11:53 AM
