  1. Earthquake & VolcanoReview

  2. The cracks in Earth’s crust are called __. Ridges Continents Tunnels Faults

  3. D. Faults

  4. Waves of energy generated (started) by an earthquake that travel through earth are called ___. A Seismic waves B. Rolling waves C. Breaking waves D. Earth waves

  5. A. Seismic waves

  6. The point on Earth’s surface where the earthquake is the strongest & most damaging is called the ___. Trigger Center Epicenter Breaking point

  7. C. Epicenter

  8. The area under Earth’s surface where rock is stressed until it breaks & starts an earthquake is called the ___. Core Focus Rock Fall Mantle

  9. B. Focus

  10. Roman numerals are used in the scale that shows the reported damage level in an area hit by an earthquake. Which scale is this? Mercalli Scale Richter Scale Earthquake Scale Geiger Scale

  11. A. Mercalli Scale

  12. The earthquake in Japan was reported as a 9.0 on the Richter Scale. What does this mean? How long the quake lasted The size/magnitude of the quake The time of day the quake began How much it will cost for repairs

  13. B. The size/magnitude of the quake

  14. What is the term for a formation near a weak spot in Earth’s crust where magma comes up to the surface? Geysers Tsunamis Volcanoes Earthquakes

  15. C. Volcanoes

  16. A string of islands that forms where 2 convergent plates collide is called ___. A mountain range An island arc A trench A subduction zone

  17. B. An island arc

  18. Choose 2 examples of island arcs. The Hawaiian Islands The Mexican Islands The Caribbean Islands The Aleutian Islands

  19. C. The Caribbean Islands D. The Aleutian Islands

  20. Hot Springs & Geysers are 2 examples of __. These may be found near areas of past or present volcanic activity. Areas of geothermal activity Areas where old people live Areas of muddy water Areas where the ground is cooler

  21. A. Areas of geothermal activity Heat Earth

  22. Where does magma form? In the outer core In the inner core In the mantle In the crust

  23. Magma forms in the MANTLE!C.

  24. Do volcanoes form at transform boundaries?

  25. No.They form at subduction zones @convergent boundaries.

  26. Where do the Hawaiian Island form?

  27. In the Pacific Ocean over a HOT SPOT.

  28. If a volcano erupts ___, the magma is thin and flows easily. Explosively Quietly Pyroclastically Strobolian

  29. B. QuietlyExplosively would be thick & sticky.The other two don’t make any sense 

  30. Name the volcano type:

  31. 1. Cinder cone2. Shield 3. Composite

  32. Wide, gently sloping volcanic mountains like the ones in Hawaii are called __. Caldera Cinder Cone Shield Composite

  33. C. Shield

  34. A tall, cone-shaped volcano that has explosive eruptions would be a __. Cinder cone Shield Composite

  35. C. Composite

  36. A cone shaped mountain that erupts ash, cinders, & bombs is a ___ volcano. Cinder cone Shield Composite

  37. A. Cinder cone

  38. Huge ocean waves created by an underwater earthquake or plate movement is a ___. Sea surge Caldera Tsunami Tidal wave

  39. C. Tsunami

  40. When a volcano collapses, a huge hole forms in the top. This called a ___. Fault Cavern Crater Caldera

  41. D. Caldera

  42. Why is it important to be able to predict where or when an earthquake may happen?
