Answer to Question 1

Answer: The wind. As winds blow across the ocean, frictional forces set the surface water into motion. The Coriolis force and interface with the land act to modify the circulation, but the driving force is the wind.

Answer to Question 2

Answer: When seawater in polar regions freezes only the water freezes, the salt is left behind. The surrounding seawater experiences an increase in salinity, which brings an increase in density. The cold, denser, saltier seawater sinks, producing a pattern of vertical movement. Movement is also horizontal as cold dense water flows along the bottom to the deeper parts of the ocean floor.
