Across
  1. 6. a factor that affects money
  2. 8. buildings in a community
  3. 10. an extreme natural event or process which threatens to cause loss of life and/or property damage
  4. 12. part of the earth’s structure that is solid, reaches up to 6000 degrees and is 5150-6370km from the surface
  5. 13. the type of plate boundary where plates slide past each other in the opposite direction or at different speeds. They cause earthquakes.
  6. 16. the scale that measures the severity of an earthquake based on observations about the damage it has caused
  7. 17. point on the surface that is directly above an earthquake’s focus
  8. 18. a factor that affects the environment
Down
  1. 1. the type of plate boundary that involves oceanic and continental plates moving towards each other. They cause volcanoes and earthquakes and subduction. An example is the mid atlantic ridge
  2. 2. services in a community
  3. 3. part of the earth’s structure that is 40-50km deep, made of hard rock and is a regular temperature
  4. 4. part of the earth’s structure that is liquid iron/nickel, reaches up to 5000 degrees and is 2890-5150km from the surface
  5. 5. the scale that measures the severity of an earthquake using a seismometer to measure the magnitude
  6. 7. part of the earth’s structure that is made of soft molten rock, reaches up to 3800 degrees and is 40-2890km from the surface.
  7. 9. the type of plate boundary that involves plates moving away from each other. This causes shield volcanoes and earthquakes
  8. 11. the type of plate boundary that involves two continental plates colliding, creating fold mountains like the Himalayas.
  9. 14. a factor that affects people
  10. 15. where the seismic waves radiate from during an earthquake
