  1. inner core outer core mantle crust

  2. reverse fault

  3. normal fault

  4. strike-slip fault

  5. thrust or reverse fault

  6. normal fault

  7. strike-slip fault

  8. P Waves push and pull motion fastest-moving waves travel in straight path move through solid and liquid material

  9. S Waves move in up-and-down zigzag pattern move more slowly than P waves cannot travel through liquid material

  10. P wave

  11. S wave

  12. Love wave

  13. Rayleigh wave

  14. Mercalli Richter measures destruction based on man’s observations measures magnitude

  15. Richter Scale Effects 4.0 - 4.9 5.0 - 5.9 6.0 - 6.9 7.0 - 7.9 8.0 - 8.9 2.0 - 2.9 3.0 - 3.9

  16. ash crater lava side vent vent magma chamber

  17. Classifying Volcanoes by shape by how often they erupt by type of eruption

  18. hill-shaped with a bowl-like crater symmetrical, cone-shaped shield cinder cone upside-down-saucer-shaped composite cone by shape

  19. shield volcano

  20. cinder cone volcano

  21. composite cone volcano

  22. cinder cone composite cone shield

  23. extinct dormant by how often they erupt active

  24. active • has erupted during recorded history • is expected to erupt again

  25. dormant • erupted in distant past • not expected to erupt again

  26. extinct • does not have a recorded eruption • is not expected to erupt

  27. quiet, runny lava; little or no cinder, ash, or steam violent, loud explosion of lava, ashes, cinders, and gases Plinian Pelean Vulcanian most powerful eruption, spewing lava, gas, and dust into atmosphere avalanche of red-hot dust and gases; pyroclastic flow Hawaiian/ Strombolian by type of eruption
