Main Body
factors influencing ocean current
1. Wind direction
Prime factor deciding the direction of wind current alongwith origin.
Eg. Somalian current towards Somalia during North West monsoon
2. Shape of the continent
Although it is not a causative agent but it influences the direction of ocean current
Eg. Brazillian landmass divide ocean current there into two parts.
3. Rotation of earth
Causes Coriolis force which bends ocean current
Southern - anti clockwise
4. Relative temperature
Also determines direction of ocean current as temperature determines density of the ocean water. Generally warm water moves towards cold waters
Ancient trade routes based on direction of ocean currents alongwith wind direction.
Multi dimensional impact of ocean current
Conclusion
Hence, ocean current is a major energy distribution tool available to nature which maintains balance between north & south
