If you get into folk stories and mythology you will see that almost every culture has a story explaining how the oceans became salty. The answer is really very simple. Salt in the ocean comes from rocks on land. Here's how it works:\n\nThe rain that falls on the land contains some dissolved carbon dioxide from the surrounding air. This causes the rainwater to be slightly acidic due to carbonic acid (which forms from carbon dioxide and water). The rain erodes the rock and the acid breaks down the rocks and carries it along in a dissolved state as ions. The ions in the runoff are carried to the streams and rivers to the ocean. Many of the dissolved ions are used by organisms in the ocean and are removed from the water. Others are not used up and are left for long periods of time where their concentrations increase over time.\n\nThe two ions that are present most often in seawater are are chloride and sodium. These two make up over 90% of all dissolved ions in seawater. By the way, the concentration of salt in seawater (salinity) is about 35 parts per thousand. In other words, about 35 of 1,000 (3.5%) of the weight of seawater comes from the dissolved salts; in a cubic mile of seawater the weight of the salt, as sodium chloride, would be about 120 million tons. And, just so you don't think seawater is worthless, a cubic mile of it also can contain up to 25 tons of gold and up to 45 tons of silver! Before you go out and try alchemy on seawater, though, just think about how big a cubic mile is.\n\nBy some estimates, if the salt in the ocean could be removed and spread evenly over the Earth’s land surface it would form a layer more than 500 feet (166 m) thick, about the height of a 40-story office building.

The high concentration of salt in the Dead Sea renders the water denser than any other body of water. The higher the density of water, the greater your bouyancy.

Salt water is more corrosive, if that's what you're looking for.

While Mara gives a good description on the origin of salts in water (all water in general) it doesn't explain why the ocean is salty and streams, lakes etc are not.\n\nBascially the ocean has no outlet. Once water reaches the ocean, it stays there, along with all it's transported salts and minerals. \n\nThe Earth has weather though, and weather is driven in a large part by evaporation of water from the Earth's oceans. \n\nWhen you evaporate the water content, you fractionally reduce the volume of water, which therefore fractionally increases the concentration of salts and minerals. You should also know that some of these salts and minerals are removed from the oceans by precipitation into sediments on the ocean floors. So over the millions of years that the oceans have been around they have grown relatively saltier than the bodies of water that contribute to the oceans.\n\nThis process is exaggerated in trapped bodies of water that recieve a lot of heating. Take the Dead Sea for example - it's an enclosed body of water and since it does not have the vast volume of the world's oceans, the salt concentration process runs much faster. The Dead Sea is currently 6x saltier than the ocean. Salt lakes on any continent are another smaller example again - you'll find them in the USA and Australia to name but two examples.\n\nCommercial Salt production uses the same process, of evaporating water to leave behind salts.

it does but it's diluted.Some bodies of water have higher salt content than others.

Dear Friend,\n\nSalt in the ocean comes from the land. The elements that make up salts, such as chlorine and sodium, started out in rocks. Water and acids eroded the rocks, and rivers carried the elements into the sea. The oceans usually contain 35 parts of salts for every 1000 parts of sea water. This is lower in some places where there is a lot of fresh water coming into the ocean. 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 solid, white crystals.\n\nThe right amount of salt is a very important part of our diet. In ancient times, salt was worth its weight in gold. People used it to flavor and preserve their food. Without salt, the food would spoil. For this reason, salt became a symbol of purity. Some sacrifices in the Old Testament included salt (Leviticus 2:13; Ezekiel 43:24). Jesus called faithful people "the salt of the earth," and the apostle Paul said that our speech should be "seasoned with salt" (Colossians 4:6).

Because theres so much water thats constantly moving that the sun can't warm it all up. The ocean is so deep, and that water is about 30 degrees (yes farenheit, which doesnt freeze because of the salt in it) that it continusoly gets mixed up and remains a constant tempertature that seems cold to us. =)

The density of water is greatly affected by salinity, or the salt concentration.  When salts are dissolved into pure water, the density of water increases because the salts have a greater density than the water; thus freshwater floats on salt water.  This is also why your ability to float differs between a swimming pool and an ocean.

there is salt in the water

The concentration of salt in seawater varies with temperature.  Because the Arctic and Antarctic oceans are colder than the Indian Ocean and South China Sea, the salt is less soluble.  By the same principle, seawater near the floor of the ocean would be less salty because it's cold down there.  Throw in a few baby volcanoes, the Atlantic rift and a few dozen fumaroles, etc...  Then, you would have to know how many liters of water are in the oceans and that quantity is constantly changing.  Now, are you talking about common NaCL?  Or do you want to include all the sulfates, carbonates, phosphates, etc... which are all in the ocean?  Thanks for the easy 2 points!

Salt comes from  dissolved rock. Rivers carry that salt from the land to the ocean. It's that simple.

the ocean is salty as it contains water colected from different sources such as rivers which bring with them different types of mineral salts before they mingle with the ocean.

There are all sorts of salts.\nIn common usage, 'salt' refers to sodium chloride. Table salt is refined sodium chloride together with various additives, e.g. anti-caking agents, iodides, etc.\nMarine/sea salt is sodium chloride from the solar evaporation of sea water. It contains associated impurities such as calcium sulphate and magnesium chloride.\nWhen I did a Google search with the term "sea salt"+"marine salt" most of the references were to do with products for marine aquariums, so I think that the phrase 'marine salt' is used to describe stuff mostly intended for aquariums whilst the term 'sea salt' is for human consumption. If this is the case then I would expect 'sea salt' to be more strictly controlled as far as imputities are concerned.

Because when the storm forms, it forms from water that has evaporated from salt water. And the salt doesn't evaporate with the water.

Salt or Sodium Chloride is highly soluble in water.  Salt is naturally occurring and large bodies of water that cover vast numbers of square kilometers come in contact with salt.  Over time it dissolves causing the water to be high in TDS or total dissolved solids such as NA CL.  When the water from oceans evaporates, the salt drops out of solution which increase the salinity of the remaining water.   The evaporated water returns to earth as fresh water which flows back into the oceans and the cycle continues.   Large Salt caverns are ancient spaces that have not been exposed to water for millions of years.
