hazards (plate boundaries (destructive (description (oceanic and…

- - - - oceanic and continental plates move together.
      - heavier, denser oceanic crust is melted and destroyed
      - explosive volcanoes
      - violent earthquakes
      - most hazardous boundaries
    - - the ring of fire
  - - - continental plates move together.
      - plates are too light to sink to the mantle
      - plates buckle and fold to form mountains.
      - volcanic activity is rare
    - - cascade mountain range
      - Andes mountain range
  - - - oceanic plates move apart
      - lava then erupts
      - new crust is formed on the sea bed
      - underwater volcanoes
      - gentle earthquakes occur
    - - the south American plate
      - iceland
  - - - tectonic plates move in different directions, or at different speeds
      - plates are locked together by friction
      - pressure builds up until a plate breaks along a fault line
      - no volcanoes
      - violent earthquakes
    - - san Andreas fault
- - - - 500 to 900
    - - 2,500km
    - - molten
  - - - 4,400
    - - 2,300km
    - - liquid
    - - iron
      - nickel
  - - - made from
        
        granite and basalt
      - state
        
        solid
      - thickness
        
        5-7km
    - - solid
      - granite and basalt
      - 10-70km
  - - - 1250km
    - - solid
    - - nickel
      - iron
    - - 6,000
- - - - disrupting passengers with hundreds of flights being cancelled
      - building were destroyed
      - ash and flooding means that farmers have to feed their animals because their food that was being supplied the surroundings have been washed away
    - - loss of tourist income as flights were suspended
      - ash clouds turn the sky black
    - - could effect breathing people breathing
      - creates a chain reaction that activates other volcanoes
      - roads were washed away
    - - farmers have good harvests because of the ashes warmth and nutrients
      - tourism
      - allowed people all over the world that the island existed and this could attract tourists
      - tourism brings in the most money out of all the industries and it got up to earning 1.7 million a year
- - - - 2,500+m in height with steep slopes
    - - more vicious and sticky and cant get far before if hardens and it can lead to more explosion eruptions
    - - these types of volcanoes are found at destructive plate boundaries
  - - - lots of volcanoes are found under the ocean in a line depending on the direction of the plate
    - - super heated magma pushes through the crust at a constant rate
    - - occurs at all plate boundaries
  - - - spreads widely over great distances and is quick
    - - the types of volcanoes are found a constructive plate boundary
    - - 9100+m in height and gentle sloping sides
- - - - if you are in a building
        
        Duck under the nearest sturdy object and hold onto it until the shaking stops. If you are not near a sturdy object, make yourself as small as possible and cover your head and neck.
        
        If you stand in a doorway, brace yourself against the frame and watch out for a swinging door or other people.
        
        Avoid windows, filing cabinets, bookcases and other heavy objects that could fall or shatter.
        
        Stay under cover until the shaking stops, and then leave the building.
        
        f it is safe to do so, stabilize any laboratory procedure that could lead to further damage, such as turning off burners or electrical equipment.
        
        Evacuate the building if told to do so by building staff or emergency responders.
      - if you are outside a building
        
        Move away from trees, signs, buildings, electrical poles and wires.
        
        Protect your head with your arms from falling bricks, glass, plaster or other debris.
        
        move away from all fire and smoke
        
        Proceed to your designated evacuation meeting point if safe to do so.
        
        Stay alert for further instructions.
