Clues

  • a perceived event that threatens both life and property. Natural Hazards often result in disaster that cause some loss of life and/or damage to the built environment that creates severe disruption to human activities (7, 6)
  • along ocean ridges where plates are moving apart and magma is forcing its way to surface, cool and form new crust. As the plates move further apart, new crust is carried away from the ridge (seafloor spreading) (3, 5, 9)
  • circular movements of liquid magma within the mantle. They determine the direction of crustal movement (10, 8)
  • form where oceanic and continental plates meet the denser oceanic plate is forced underneath the lighter continental one (subduction). The downwarping of the oceanic plate forms a deep part of the ocean known as a trench (4, 3, 8)
  • L waves/Love waves and Rayleigh waves travel along the surface only (7, 5)
  • largest section of the mantle and core (13)
  • the spatial coverage of the hazard. This can refer to the area affected by the single event, some of which can have a very localised event, while others have a much wider effect, such as tsunamis which can cross large oceans (12)
  • travel slower through the crust. These waves cause the crust to move from side to side at right angles to the outward motion of the main wave causing the most damage (10, 5)
  • where people try to return the state of things to normal by providing food, water and shelter for those most affected. This period can last anything from a few days to weeks (14)
  • where the infrastructure and property are reconstructed and crops are grown. At this time people use the experience of the event to try to learn how to better respond to the next one. This period can take from weeks to several years (14)
