Clues

  • Focus: the point at which the disturbance occurs. Epicentre: the point on the ground directly above the focus. Shockwaves: radiate out in all directions from the focus. (10, 8)
  • Found on constructive boundaries. Characteristics: regular and frequent eruptions, not explosive, runny lava, gentle slopes, wide base and made of lava only. Example: Surtsey Island, Iceland. (6, 9)
  • Found on destructive boundaries. Characteristics: subsidiary cones, made of lava and ash, irregular, violent eruptions and tall, steep sides. Example: Mt. Etna, Italy (9, 7)
  • Terraced/stepped farming, HEP, and tourism (e.g. skiing). (4, 2, 4, 9)
  • These are 1000 times larger than a usual volcano. When it erupts, global cooling occurs, the magma chamber collapses and a caldera is formed. Example: Yellow Stone, US. (14)
  • These are formed in the subduction zone of a destructive margin. (5, 8)
  • These are formed when sediment between plates at a collision plate boundary turns solid, and is then pushed upwards by the movement of the plates. (4, 9)
  • These are what the crust is split up into. They 'float' on the surface of the mantle and are moved by the convection currents which occur there. (8, 6)
  • This indicates the earthquakes impact on the people, with I being little/no damage and XII being total destruction. (9, 5)
  • Tiltmetres: checks for bulges. A bulge could indicate a build up of magma. Satellites: monitor heat changes. If the heat increases, it could indicate the presence of magma. (10, 9)
