Earthquakes/volcanoes

    Cards (16)

    • Why do plates move?

      because of convection currents
    • where are convection currents
      where the inner core heats the mantle, causing magma to rise up
    • Which direction do plates move in?

      Towards eachother (destructive)
      Away (constructive)
    • What happens when the plates move?

      The oceanic crust sinks under the continental crust because it's heavier
    • How does this movement cause an earthquake and/or a volcano

      As the plates move they get stuck and pressure builds up. When this is released it forms an earthquake
    • Destructive

      plates move towards eachother
    • Constructive

      Plates move away from each other
    • What are the 3ps

      Predict, protect, prepare
    • Depth

      A shallow earthquake means the shaking is more violent
    • Distance

      A closer earthquake means the shaking is more violent
    • Secondary hazards

      More secondary hazards means more death and destruction
    • What does soft rock do during earthquakes

      Soft rock vibrates more during an earthquake
    • Is it better to be awake or asleep during one
      If people are asleep they are more likely to die
    • Magnitude

      The stronger the earthquake the more damage
    • Population density

      The higher the population density the more deaths that will occur
    • Level of development 

      LICs have less emergency services whereas HICs have more so HICs are more likely to survive
