Clues

  • 300 – 720 km deep (4, 5, 11)
  • A computer imaging technique, based on seismic wave velocities (7, 10)
  • A layer or shell of the crust and upper mantle, in which the rocks are rigid and brittle - The base is taken as the 1300'C isotherm and varies in thickness (11, 5)
  • Also called constructive as new material is added to the crust (9, 7)
  • Also called destructive as oceanic crust is ‘lost’ along the subduction zones (10, 7)
  • Carries a continent but will also have oceanic crust (11, 5)
  • Has no continental material (7, 5)
  • The large-scale horizontal movement of continents during geological time (11, 5)
  • Towed behind a ship to measure changes in magnetism - It can detect the strength and direction of the magnetic field (12)
  • Where the downward movement of an oceanic lithospheric plate, beneath another plate, is ‘destroyed’ by partial melting as it descends into the mantle (10, 4)
