Deep Ocean Density Currents and Salinity

Investigate how variations in water temperature and salinity create deep ocean density currents. Understand how these underwater movements drive deep-water ocean circulation.

Questions

  1. MultiChoice

    What two physical properties drive deep ocean density currents?

  2. MultiChoice

    What is the global deep-water circulation system driven by density differences called?

  3. MultiChoice

    What happens to seawater density when its temperature drops near polar regions?

  4. MultiChoice

    How does higher salinity affect seawater density?

  5. MultiChoice

    What happens to ocean salt when sea ice forms in polar seas?

  6. MultiChoice

    Where does deep ocean water primarily form and sink downward?

  7. MultiChoice

    Why is deep ocean water typically cold and salty?

  8. MultiChoice

    How does high evaporation in warm subtropical oceans affect surface salinity?

  9. MultiChoice

    What happens to ocean water density when melting glaciers pour freshwater into the ocean?

  10. MultiChoice

    Why do deep ocean currents move much slower than surface ocean currents?

  11. MultiChoice

    What component of 'thermohaline' refers to salt content?

  12. MultiChoice

    What crucial role does deep water formation play in global ocean movement?
