Describe how density currents form.
Cold air blows from over land to the ocean, cooling the water and making it freeze. As ocean water freezes, the liquid water becomes more salty and dense. The cold dense water sinks toward the ocean floor.
Name two factors that influence the direction of Ocean Currents.
Coriolis Effect, Landmasses, Shape of continents.
