Chapters 8-10 Review Answers Page 243: 2. epicenter 3. lithosphere 4. a seismograph 7. the focus 8. liquefaction 9. three 10. moment magnitude 11. a seismogram 12. A: P-waves, B: S-waves, C: surface waves 15. fire, landslides, liquefaction and tsunamis 17. Liquefaction is when stable soil behaves like a liquid and is unable to support structures and buildings. 19. 100 times Page 275: 2. at plate boundaries 3. continental drift 4. continental-continental convergence 8. oceanic-continental convergent 10. mechanism of continental drift 13. Earthquake patterns show where the plate boundaries are and show how slabs of lithosphere are subducted into the mantle. 14. a divergent boundary with oceanic lithosphere 15. Lithosphere is created at divergent boundaries like mide-ocean ridges while it is destroyed at convergent boundaries where there is a subduction zone 16. Hot spots 17. Convergent boundaries 23. A subduction zone at a convergent boundary. Oceanic and continental lithosphere . 24. Subduction of one slab below the other causes friction that melts the rock. The magma that is produced is what creates the volcanic activity above Page 303 2. eruptions along ocean ridges 3. composite cones 12. The Ring of Fire is the name given to the volcanoes that are located around the margin of the pacific plate. 14. continental volcanic arc 16. shield volcano 17. quiet eruptions of low viscosity lava 20. Viscosity is the resistance to flow, or in other words, how thick a fluid is. High viscosity lava (high silica content) produced violent eruptions like those from a composite cone volcano. Low viscosity lava (low silica content) produces relatively quiet eruptions like Hawaii. **Don’t forget to also study your vocab, notes and warm up questions**
