ocean current
Seawater's steady movement
An ocean current is a continuous, directed movement of seawater driven by wind, temperature differences, salinity, and the Earth's rotation.
Surface currents like the Gulf Stream carry warm water across vast distances, influencing weather patterns and climate along coastlines.
Deeper currents move more slowly, driven by differences in water density.
Together, these currents form a global circulation system that distributes heat, nutrients, and marine life throughout the world's oceans.
