SALINITY The salinity (salt content) of ocean water varies. The oceans and seas contain roughly 5 x 10 16 tons of salts. One cubic foot of average sea water contains 2.2 pounds of salt. The oceans are about 3.5% salt (by weight). Salinity is generally reported in terms of parts per thousand (abbreviated o/oo), the number of pounds of salt per 1,000 pounds of water; the average ocean salinity is 35 o/oo. The saltiest water is in the Red Sea and in the Persian Gulf, which have a salinity of about 40 o/oo (due to very high evaporation rates and low fresh water influx). The least salty seas are in the polar regions, where both melting polar ice and a lot of rain dilute the salinity.
This is lower in some places where there is a lot of fresh water coming into the oceans. It is higher where the sun is very strong and evaporates more of the water. When all the water is gone ,the salts are left behind as solids, white crystals. The right amount of salt is a very important part of our diet. In ancient times, salt worth it s weight in gold. People used it to flavor and preserve food .Without salt, the food would spoil. For this reason .Salt became a symbol of purity. Some sacrifices in the old testament included salt.
The reason why the ocean is so salty unlike other bodies of water is because of weathering and erosion. When water evaporates and goes into the clouds it condenses. When there is too much water located in the clouds it precipitates which is just another word for rain. When it rains instead of going directly to lakes, ponds, canals, and rivers it carries the rock in to the ocean in a process called erosion. While the rain carries the rocks to the ocean it breaks down the rock into minerals, this process is called weathering.
Weathering is another natural process that replenishes sodium dioxide into the ocean. There are three different kinds of weathering. They are Chemical Weathering, Physical Weathering and Mechanical Weathering. These processes have constantly erodes Earth's lithosphere therefore filtering sodium dioxide from from the Earth into streams, tributaries, and rivers, which eventually ends up into the ocean.
To remove Sodium Dioxide from the the Ocean, one will have to completely eradicate this mineral from the lithosphere. Since Sodium Dioxide is a renewable natural resource, as far as we know it, it is impossible to completely remove this mineral from the Earth.
