Current

Currents are the continuous, directed flow of seawater in the ocean. They can be caused by various factors, including wind, temperature differences, salinity variations, and the Earth’s rotation. Currents are crucial in distributing nutrients, heat, and marine life throughout the ocean. They can be classified into two main types: surface currents, which occur in the upper layer of the ocean and are driven primarily by wind, and deep ocean currents, which flow in the deeper layers of the ocean and are driven by differences in water density and temperature.
