1. Final Exam Review Unit 2: Natural Disasters

2. Earthquake violent shaking of the ground

3. Cause of Earthquake Movement of tectonic plates Subduction zone Transform fault

4. Type of damage from an Earthquake destruction, building damage, road damage, ruptured pipes, death

5. Where Earthquakes occur at plate boundaries

6. Safety during an Earthquake

7. Relationship to Tsunamis Cause of a tsunami, displaces a large amount of water at subduction zone

8. Richter Scale measures magnitude of earthquake, 1-10 (10 the worst)

9. Tsunami

10. Cause of a tsunami displacement of water, earthquake under water

11. Type of Damage Flooding, mass destruction

12. Warning of a Tsunami Water recedes, recent earthquake

13. Safety during a Tsunami Run to higher ground

14. Volcano Movement of tectonic plates, subduction zones

15. Damage Lava flows, Property destruction

16. Where? Plate boundaries- subduction zones

17. Dormant A volcano that has not erupted in a long time but has the potential to erupt again Cattle Graze Beneath the Dormant Volcano Mt. Taranaki or Egmont Taranaki New Zealand

18. Active A volcano that is currently erupting

19. Extinct A volcano that has erupted in the past but will not erupt again

20. Active DormantExtinct

21. Magma Molten rock below Earth’s surface, before it erupts from a volcano Lava Molten rock above Earth’s surface, what is erupting from a volcano

22. Tornado Forms from a supercell thunderstorm a cold air mass and a warm air mass combine- the cold air mass drops below the warm air mass eventually twisting

23. Where they form Flat land Tornado alley

24. Type of damage Mass destruction of anything in its path

25. Safety

26. Fujita scale measures the intensity of a tornado on a scale of 1-5 (5 the worst)

27. Hurricane Forms over warm water

28. Type of damage 1.Storm surge- flooding 2.Wind- downed trees, flying debris

29. Wind Speed Greater than 74 mph

30. Storm Surge water from ocean gets pushed onto shore causing flooding

31. typhoon Pacific ocean cyclone Indian Ocean

32. Forest Fires Cause – Human: main cause of forest fires, arson, campfires, cigarettes – Nature: lightening, sun

33. Fire Triangle Fuel Oxygen Heat Source

34. Controlled burning removes fuel for a fire- undergrowth, brush, leaf litter

35. Where they occur In dry, arid areas such as out West- heat, drought, frequent thunderstorms

36. Damage habitat destruction property damage

37. Benefits Clearing the forest floor providing habitat killing disease new generations
