Moreover, the rain replenishes the water streams and rivers, making them not taste salty. Please use them. Is a salinity monitoring network "Worth its salt"? Gases from volcanoes dissolved in the water, making it acidic. These images attempt to show three dimensions, so each sphere represents "volume." The reason the sea is salty is because it is very old. Stream and river water does not taste salty because it is moving, compared to the Ocean, which is essentially a giant bath tub. Around 3.5% of ocean water is comprised of salts, depending on where in the world one is; equatorial waters tend to be saltier, while northern waters are slowly becoming more fresh. Thawing action also helps in reducing salt content in the ocean since the ice melting in polar regions produce fresh water which dilutes accumulated salts. Why Is the Ocean Salty?

(More-advanced techniques later revealed this to be a major underestimate; the actual age is more like four billion.)

The Ocean is salty because of dissolved land materials that are deposited into the Ocean through streams and rivers. Ocean water in the tropics is more saline than in polar regions because the sun is higher and evaporates higher, making it have higher salt concentration.
