  1. Volcano Quiz Prep

  2. SOME STUDY IS HIGHLY RECOMMENDED BY THE MANAGEMENT

  3. What Type of Volcano?

  4. A • Cinder Cone

  5. What are cinder cones made of?

  6. A • Loose bubbly light weight chunks of rocks • Rubble

  7. Why are cinder cones not steeper?

  8. A • Cinder Cones have moderately sloping sides because loose rubble doesn’t stack well.

  9. What Type of Volcano?

  10. A Shield

  11. Why are shield volcanoes not steeper?

  12. A • The lava shield volcanoes are made of is very thin and travels long distances before it hardens.

  13. Why are Shield Volcanoes generally good neighbors?

  14. A • They don’t explode • Their lava moves slowly enough to be avoided

  15. Why don’t shield volcanoes explode?

  16. A • They are made of solid basalt which is VERY strong

  17. What Type of Volcano?

  18. Composite A

  19. Why are composite volcanoes named composite?

  20. They are composed of many different types of layers A

  21. What is the tallest type of mountain on Earth?

  22. A • A shield Volcano named Mona Loa in the Hawaiian Islands.

  23. Which type of volcano is most likely to blow up?

  24. A • Composite

  25. Why do Composite volcanoes tend to blow up?

  26. A • They are very weak because many of their layers are nothing but ash or cinder. When too much pressure builds up, they blow their layers apart.

  27. Which type of volcano makes a lot of noise and fireworks, but isn’t too likely to explode?

  28. A • Cinder Cone

  29. Where can we find cinder cones in the United States?

  30. A • Arizona and New Mexico

  31. What Type of Volcano?

  32. What caused the Hawaiian Islands to form?

  33. A • Hot spots in the mantle

  34. Why are there so many Hawaiian islands from 1 hot spot?

  35. A • The Earth’s crust is moving, but the hot spot is not. Consequently, new volcanoes form over the hot spot after the old ones move away.

  36. What type of volcano is found at Yellowstone?

  37. A • A Supervolcano

  38. Why did they have a hard time locating the Yellowstone Volcano?

  39. A • It is so big that you have to be in space to see the whole caldera.

  40. Where in the United States can we find a LOT of shield volcanoes?

  41. A • Hawaii

  42. Why are Cinder cones unlikely to explode?

  43. A • The cinder rocks are loose, so the new lava can just push the old lava out of the way.

  44. Where can we find some composite volcanoes in the USA?

  45. A • Along the Pacific coast in Washington and Oregon.

  46. What caused these coastal volcanoes to form?

  47. A • The Cascade range was formed by a subduction zone where the oceanic plate is sliding under the continental plate.

  48. What sorts of problems could supervolcanoes cause?

  49. A • Loss of sunlight • Loss of summer • Extinctions (maybe of people) • Loss of crops and animals • Starvation • Economic collapse • Wars • Mass emigration to other countries

  50. Volcanoes with quiet eruptions occur in what 2 places?
