  8. 26. What type of natural hazard is likely to be more intensive due to climate change?
  9. 27. What causes plates forming a conservative margin to get stuck as they pass each other?
  10. 28. What is the layer, present below the atmosphere, consisting of the Earth’s crust along with the uppermost solid layer of the mantle?
  11. 29. What type of volcano is typically found along constructive plate margins?
  12. 30. Which theory of tectonic movement suggests plates move due to gravity pulling a tectonic plate into the mantle along destructive margins?
  13. 31. What is molten liquid rock above the surface of the Earth known as?
Down
  1. 1. Ocean ridges are typically found along which type of plate margin?
  2. 2. The San Andreas fault occurs along which type of plate margin?
  3. 3. What type of effect is one that is directly caused by the disaster, is an integral part of the disaster itself; in the case of an earthquake, it would be the ground shaking, or in the case of a volcanic eruption, lava pouring out of the volcano?
  4. 4. The Mid-Atlantic Ridge is located along which type of plate margin?
  5. 5. What is an extreme natural event that threatens people or has the potential to cause damage, destruction and death known as?
  6. 6. Where do volcanoes occur in addition to constructive and destructive plate margins?
  7. 7. Where do over half the world’s volcanic eruptions and earthquakes occur?
  8. 8. Along which plate margin do rift valleys occur?
  9. 10. What type of margin do the North American and Eurasian plates form?
  10. 11. What type of margin do the Pacific and Eurasian plates form?
  11. 13. What type of effect involves the things that happen in the hours, days, and weeks after a disaster?
  12. 15. What are the large pieces of lithosphere known as?
  13. 17. Which theory of tectonic movement suggests plates move due to gravity causing the higher plate at a ridge to push away causing them to move away from each other?
  14. 19. Some scientists believe plates move due to heat currents in the mantle. What are these currents called?
