What Are The Characteristic Of Saltwater?

Of course, high salt content. Also, many species of fish cannot survive in salt water, fresh water fish for instance. There is also high buyancy, meaning it is denser than fresh water so easier to float things, many plants cannot survive do to high salt content as well.  Cannot drink as will cause dehydration rather than hydration in people. Will cause chaffing of skin, as it will solidify on skin and cause it to crack.  Salt can be extracted from water.  Salt in water also a great healer for open wounds.  Ghandi used the salt, extracted from the ocean to show people can be self sufficient by producing and selling. It is markateble.  Though swimming in salt water, when bathing in such, has high healing potential.  The dead sea, water content so high in salt, no thing can survive, if you plunge in, will not sink.  Freezes at a much higher level than regular water.  Add salt to water, you can make ice cream, as water will not freeze, but cream in seperate container immersed in salt water will freeze faster due to lack of salt etc. Etc. Hope this helps
