    Why Sea Water is Salty The “salt” in sea water‚ and some lakes that have no water outlet such as the Great Salt Lake and the Dead Sea‚ comes from ions of dissolved minerals‚ mainly chloride and sodium which make up about 90% of salt ions in sea water. There are three main ways that dissolved minerals enter the ocean: The water cycle‚ underwater geysers know as Hydrothermal Vents‚ and underwater volcanos. During the water cycle‚ water is evaporated from bodies of water by the heat of the
