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.
Depth contours, shoreline configurations, and interactions with other currents influence a current's direction and strength. Ocean currents flow for great distances, and together, create the global conveyor belt which plays a dominant role in determining the climate of many of the Earth âs regions. More specifically, ocean currents influence the temperature of the regions through which they travel. For example, warm currents traveling along more temperate coasts increase the temperature of the area by warming the sea breezes that blow over them.
