What best describes an ocean current?
A large mass of moving water in the ocean
An ocean current is a continuous, directed movement of a large body of seawater along a definite path, rather like a river flowing within the ocean. Examples are the Gulf Stream and the Kuroshio Current.
Ocean currents are driven by the prevailing winds, by differences in water temperature and salinity (and so in density), and are shaped by the Earth's rotation and the outline of the continents. Warm and cold currents strongly influence the climate of coastal lands.
A collection of floating plants is a patch of vegetation, such as the Sargassum seaweed of the Sargasso Sea, not a current. No part of the ocean is free of salt, since seawater everywhere contains dissolved salts.
A stationary area is the opposite of a current, because a current is by definition water in motion. So an ocean current is best described as a large mass of seawater moving in a definite direction.
Hence, A large mass of moving water in the ocean.
