Oceanic currents are large-scale movements of seawater that flow through the world's oceans. These currents are driven by factors such as wind, the Earth's rotation, and differences in water temperature and salinity. They play a crucial role in regulating the Earth's climate by distributing heat from the equator to the poles. There are two main types of oceanic currents: surface currents and deep-water currents. Surface currents, like the Gulf Stream, are primarily influenced by wind and can affect weather patterns. Deep-water currents, part of the global conveyor belt, are driven by density differences and help circulate nutrients throughout the ocean.
