Origin Of Ocean Currents. Currents are cohesive streams of seawater that circulate through the ocean. This is due to the Coriolis force which is a deflective force and follows Ferrels law. Characteristics of Ocean Currents arise due to the interplay of the above-mentioned factors. A lthough the approximate position and strength of the main ocean currents have been known for upwards of two hundred years it is only in the last few decades that oceanographers have attempted to explain them on the basis of sound physical theory.
Ocean currents have a number of direct and indirect influences on human activities. It all starts with surface currents carrying warm water north from the equator. Characteristics of Ocean Currents arise due to the interplay of the above-mentioned factors. The factors responsible for origin of ocean currents may be discussed as. Today much new information. Early in the 20th century the term Coriolis force began to.
Ocean current stream made up of horizontal and vertical components of the circulation system of ocean waters that is produced by gravity wind friction and water density variation in different parts of the ocean.
Difference of density and salinity in ocean water motivates denser. The coastward movement of tides causes flood currents which pile up seawater against the sea coast. Cold-water ocean currents occur when the cold water at the poles sinks and slowly moves towards the equator. Water currents are generated by ocean tides due to upward and downward movement of sea level in the open and near shore regions. Ocean currents are also generated in polar areas due to high water level resulting from low evaporation due to exceptionally low temperature and abundance of water due. The currents in the oceans are originated due to combined effects of several internal as well as external factors which control the origin and other characteristics of ocean current.
