Sea water has been defined as a weak solution of almost everything.Ocean water is indeed a complex solution of mineral salts and of decayed biologic matter that results from the teeming life in the seas.MOst of the oceans salts were derived from gradual process such as the breaking up of the cooled igneous rocks of the earth crust by the weathering and erosion, the wearing downs of mountains, and the dissolving action of rains and streams which tranported their mineral washings to the sea.Some of the oceans salts been dissolved from rocks and sediment below its floor. Other sources of salt include the solid and gaseous materials that escaped from the earhts crust through volcanic vents or the originated in the atmosphere.

Hi there, This is why the sea is salty; The ocean—the seas—are made up of 96.5 percent pure water. The remaining 3.5 percent is made up of 75 other elements. Six elements are responsible for 99 percent of the sea's saltiness. They are: chloride, sodium, sulfur, magnesium, calcium, and potassium. Most of the saltiness comes from the compound sodium chloride (ordinary table salt). Where do the elements come from? The wearing away of rocks on land. As rock erodes, rivers carry the salts and other minerals to the ocean. Volcanoes and undersea springs also release salts to the ocean...
