What effects current flow in the ocean?

Current flow in the ocean is primarily driven by wind patterns, the Earth's rotation (Coriolis effect), and differences in water density due to temperature and salinity variations. Wind creates surface currents, while the Coriolis effect causes these currents to curve. Additionally, thermohaline circulation, driven by changes in temperature and salinity, influences deeper ocean currents. Together, these factors create a complex system of interconnecting currents that distribute heat and nutrients around the globe.
