WebOcean currents are simply masses of water in motion and these circulate the water and all that’s in it. Driven by wind and other forces, currents on the ocean surface cover our planet. Some span hundreds to thousands of miles across vast ocean basins in well-defined flows. WebJan 3, 2024 · How Ocean Currents Work. With water, colder and saltier equals denser. At the earth’s poles, when water freezes, the salt doesn’t necessarily freeze with it, so a large volume of dense cold, salt water is left behind. When this dense water sinks to the ocean floor, more water moves in to replace it, creating a current.
