How does ocean currents work?

Ocean currents are large-scale flows of seawater driven by factors such as wind, the Earth's rotation (Coriolis effect), differences in water temperature and salinity, and the shape of Coastlines. Surface currents, primarily influenced by wind, move water horizontally across the ocean, while deep currents, often referred to as thermohaline circulation, involve vertical movement driven by variations in temperature and salinity. These currents play a crucial role in regulating the Earth's climate by distributing heat and nutrients across the globe. Overall, they are essential for marine ecosystems and global weather patterns.
