Why the Sea is Salty :: essays research papers

Why is the sea salty? One theory states that the sea is salt because of the mid-Ocean intermission. Fresh basalt flows up through the rift along with juvenile water water that is made up of many of the components of sea water including chlorine, bromine, iodine, and many other molecules. Also some salts get into the maritime through volcanoes and even fresh water rivers carries salt into the sea. The sea is composed of many other things. Scientist over the years has conducted many experiments to prove not single of what the sea is made bring forth but also many other things. In 1715 a scientist named Edmund Halley had a theory to prove the age of the ocean by the rate of salt that is transported through the rivers. In 1889 a scientist by the name of John Joly decided to test this theory and found out the sea is most ninety million years old. Also another scientist by the name of Antoine Laurent Lavoisier conducted the first analysis of seawater two hundred years ago. Another i mage developed by John Murray in the nineteenth century states that the weight is never determined but instead the total amount of chloride ion is carefully calculated and a total for all other ions is computed by applying the constancy of relative proportions. Also A.M. Marcet, Johann Forchammer, and Wilhelm Dittmar have researched this theory. Now in the last forty years geochemist have really began looking into the chemistry of the ocean. Not only can the chemistry tell us what the sea is made have but also a history of the sea. For example the salinity of the sea has not really change in its history. The reason the seas salinity has not changed is because of its strong buffering zones. directlys scientist has also begun to look at rain as it reaches the sea.
