Deep Ocean Density and Thermohaline Circulation

Investigate how water temperature and salinity drive deep ocean density differences. Understand the global thermohaline circulation system that moves deep ocean water across the globe.

Questions

  1. MultiChoice

    What drives deep ocean currents?

  2. MultiChoice

    What is the global system of deep ocean currents often called?

  3. MultiChoice

    Cold water is denser than warm water, so what does cold surface water do?

  4. MultiChoice

    Water with high salinity is denser than water with low salinity. What does salinity mean?

    Where does deep ocean water primarily form and sink?

  6. MultiChoice

    How long does it take for deep ocean water to complete one loop through the global conveyor belt?

  7. MultiChoice

    What happens to the surrounding water when sea ice forms in polar regions?

  8. MultiChoice

    Deep ocean currents move water in what proportion of the ocean?

  9. MultiChoice

    What happens to oxygen levels in deep ocean currents as they travel from the poles?

  10. MultiChoice

    What is thermohaline circulation driven by?

  11. MultiChoice

    Which density characteristic describes cold, salty ocean water?

  12. MultiChoice

    What prevents deep ocean currents from moving in a straight line across the seafloor?
