  • What direction do Constructive plate boundaries
    separating
  • List 3 ways people predict earthquakes
  • Provide a positive in relation
  • What is a mercalli scale
    Observation, provides rate of damage
  • List 2 ways people prepare for earthquakes
  • What's the difference between a Richter scale and a seismograph
    Richter scale measures the strength of an earthquake and seismograph measures the waves
  • List a negative in relation to an earthquake
  • Explain the term aftershock
    Small waves after an earthquake
  • Explain the term focus
    the underground starting point of the earthquake
  • Explain the term 'fault line'
    A long crack in the earth surface where two plates meet
  • Explain the term 'convection currents'
    The heat from the mantle rises and cools from the earth, this continues in a cycle, causing plates to move

    colliding

  • Explain the term epicentre
    Directly above the focus on the earths surface
  • Explain the term 'subduction'
    When plates colllide and the heavier Plate is recycled back into the mantle
