  7. 10. Currents that are caused by the differences in the density of ocean water. These currents move and mix water around the world.
Down
  1. 1. Movement of ocean water caused by density difference brought about by variations in temperature and salinity. As ocean water freezes at the poles it concentrates salt, and the colder, denser water sinks.
  2. 6. process in which chemicals are converted into energy
  3. 9. mass/volume; the degree of compactness of an object
