Surface ocean currents are driven mainly by winds and are affected by seasons.Deep ocean currents are driven mainly by density and temperature gradients. However the most important and fundamental causes for the formation of the ocean currents are solar heating,winds and gravity. Source(s): Arasan Â· 9 years ago.
There are two types of ocean currents: surface currents and deep water currents. Primary forces such as solar heating and winds start ocean currents. Secondary forces, including gravity and the Coriolis force, direct where the current goes. These are some of the facts about ocean currents.
