An ocean current is a continuous, directed movement of seawater generated by various factors, including wind, water density differences, and the Earth's rotation. These currents can be found at the surface or deep within the ocean and play a crucial role in regulating the Earth's climate by distributing heat around the planet. Ocean currents are classified into two main types: surface currents and deep-water currents. Surface currents, like the Gulf Stream, are primarily driven by wind and affect the upper layers of the ocean. In contrast, deep-water currents, part of the global conveyor belt, are influenced by temperature and salinity variations, contributing to the overall circulation of ocean water.
