Across
  1. 6. Plate boundary, When plates separate, e.g. Mid Atlantic Ridge.
  2. 7. Type of convergent plate boundaries, two ocean plates colide.
  3. 9. Plate boundary, When plates colide. e.g. Himalayas.
  4. 10. Type of crust, Thick (40km), Made up of light rocks, Made from silica and aluminia(SIAL).
  5. 11. Plate boundary, When plates slide past eachother, e.g. San Andres Fault.
Down
  1. 1. Type of convergent plate, Two continental plates collide.
  2. 2. Line between the liquid lower mantle and solid.
  3. 3. Type of convergent plate boundaries, ocean and continental plates colide.
  4. 4. Earths crust and solid upper mantle.
  5. 5. Boundary between earths crust and mantle.
  6. 8. Thinner (3-10km), Made up of heavy rocks, Also made from silica and magnesium (SIMA).
