Where the salinity of an ocean is high;
the ocean water is dense and flows at the ocean surface towards a low salinity area
the ocean water is dense and creeps at the bottom of the ocean towards low salinity areas
the ocean water is light and flows at the area surface towards a high salinity area
the ocean water is light and flows at the ocean surface towards a low salinity area
Explication
Salinity is one of the causes of ocean currents. Where the salinity of an ocean is high, the ocean water is dense or heavy and creeps(or moves) at the bottom of the ocean to low salinity areas.
