What makes ocean currents flow? Tides contribute to coastal currents that travel short distances. Major surface ocean currents in the open ocean, however, are set in motion by the wind, which drags on the surface of the water as it blows. The water starts flowing in the same direction as the wind.
How do currents work?
As water moves towards the North Pole it gets colder it also has a higher concentration of salt because the ice crystals that form trap.
