Clues

  • At constructive margins in continental areas, crust falls between parallel faults to form a (4, 6)
  • Earthquakes that occur at constructive plate boundaries are generally (7, 5)
  • New crust forms, at right angles to the plate boundary (9, 6)
  • Rift valley example is 4,000 km long from Mozambique to the Red sea (7, 4, 6)
  • Rift valleys are also associated with ......(Kilimanjaro) due to the thinning crust a result of tension in the lithosphere (8, 8)
  • Space between constructive (divergent) boundaries is filled with (9, 4)
  • Spreading of the plates occur at different rates leading to friction and (11)
  • Volcanic activity also occurs along the ridge forming (9, 9)
  • When constructive boundaries continental crust move apart producing (4, 7)
  • When constructive boundaries oceanic crust move apart produce (3, 5, 6)
