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

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

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.
