Question

Give reason ocean located at the same latitude do not have same saliniyy

Answer 1

The distribution of dissolved salts in the oceans and adjacent seas varies in space and time.salinity is changed near the sea surface by participation and evaporation of fresh water and by salty water produced sea ice from and excludes salts. Geographical variation in inputs create regional difference in salinity at the sea surface. As sea water circulates down into the ocean away from the sea surface , it carries these differences along, creating large scale salinity patterns throughout the ocean.
