Clues

  • A distinct column of hot mantle material which is rising towards the surface of the Earth, creating intra-plate volcanism. (6, 5)
  • A large area of the Earth's crust which is stable moves slowly around the Earth's surface. (8, 5)
  • A mixture of water from glaciers melting during a volcanic eruption and volcanic material which is then washed down river valleys and can create serious flooding issues during a volcanic eruption. (11)
  • A record of the orientation of past magnetic fields recorded in igneous rocks as they are erupted at mid-ocean ridges. (14)
  • An extremely dangerous cloud of solid rock, lava, ash and volcanic gases erupted from some volcanoes. It can travel at speeds of up to 200 km/hr. (11, 4)
  • Movement of hot material in the Mantle which is thought to be the primary driver of tectonic plate movement. (10, 7)
  • The conversion of solid land into liquid due to the shaking occurring in an earthquake. This often leads to the sinking and collapse of buildings on soft sediments. (12)
  • The edge of a tectonic plate where tectonic activity is most focused. (5, 8)
  • The theory of how tectonic plates move around the Earth's surface. (5, 9)
  • Volcanic eruptions that occur in the middle of a tectonic plate rather than on the margins. (5, 5, 9)
