The term for the movement of water in the ocean is "ocean currents." These currents are continuous, directed movements of seawater generated by factors such as wind, temperature differences, salinity, and the Earth's rotation. Ocean currents play a significant role in regulating weather and climate patterns, distributing heat across the planet, and affecting marine ecosystems. They can be surface currents, like the Gulf Stream, which circulate warm water, or deeper currents that contribute to global thermohaline circulation. Understanding ocean currents is vital for navigation, weather forecasting, and environmental sustainability.
