  9. 10. Boundary when two plates are sliding it forms what boundary
  10. 12. the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.
  11. 14. Crust the uppermost layer of the oceanic portion of a tectonic plate.
