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

elements based on their chemical and physical properties was made by German chemist Johann Dobereiner. In 1817 Dobereiner noticed that certain elements that were chemically similar could be grouped together in threes‚ for example‚ calcium‚ strontium‚ and barium; lithium‚ sodium‚ and potassium; chlorine‚ bromine‚ and iodine. In each group of three‚ the atomic weight of one element fell halfway between the atomic weights of the other two elements. Based on his discoveries‚ Dobereiner proposed the Law of Triads
