How thick do you want the layer? when you find out, are you going to do it?\nNO??????\nSo, why are you asking??????

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.

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

The oceans are in relative equilibrium.  They aren't getting saltier.  There are several salt "sinks" which take the accumulated salt and remove it from the ocean.\n\nThe following is an excerpt from this Web reference on the subject:\n\nb. Sinks (removal processes) of ocean salinity include salt spray which is blown over land; at oceanic ridges magnesium and sulfate ions are incorporated into mineral deposits; calcium, sulfate, and sodium are deposited as biogenous sediments in animal shells and fecal pellets; most importantly, almost all ions can be absorbed to the surface of sinking clay and biological particles.\nhttp://www-ocean.tamu.edu/~duce/chapter07.html\n\nDoing a Yahoo Search for:\nocean salinity salt removal\nhttp://search.yahoo.com/search?p=ocean+salinity+salt+removal&ei=UTF-8&fr=slv1-&x=wrt\n\nyou can find a number of related articles that talk about what happens to the salt.\nhttp://www.palomar.edu/oceanography/salty_ocean.htm\nhttp://www.geo.arizona.edu/geo2xx/geo212_2/Lectures/OC05.SaltGas.pdf#search='ocean%20salinity%20salt%20removal'\nhttp://www.oceansonline.com/salts.htm

Salt is carried into the oceans by the rivers that flow into it from land.  The river water absorbs salt from the rocks and minerals in the earth; the amount in the river water is small, so the water is not salty, but once it gets into the ocean the salt accumulates.  When ocean water evaporates back into the atmosphere, the salts stay behind and accumulate.  It takes thousands of years to build up to the present concentration, but it is still going on.

1.34 billion cubic km of water is available on earth but 96.5% of water is found in the sea that is saline.only 0.0002% is running water, and 0.76% is groundwater. so you see we already have very less freshwater at our disposal. with the booming population and increasing number of industreis our usage of freshwater is also increasing. thats is the reason for the shortage of freshwater.

I've actually seen more than a square yard of gold before, so I can guarantee you that is not correct.  How much there is on earth can not be discovered for the simple reason that man has not found every gold deposit on the planets surface.  Keep in mind that 2/3-3/4 of the planet is under water and we don't mine for gold there either :)

~If one uses the technical definition, there is only one salt water ocean, covering approximately 75% of the earth's surface, making it number two to the largest ocean, the atmosphere.

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!

Because of the sea salt.

Salt 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.

Flood an area with salt water and let the water evaporate.  Repeat a bunch of times and you'll have a layer of salt to scrape up.

The salt gets dissolved in the water.

Sea salt comes in fine or larger crystals. In nature it includes not only sodium chloride, but also other vital trace minerals.\ncheck out this article it should help: http://en.wikipedia.org/wiki/Sea_salt\nAlso: http://en.wikipedia.org/wiki/Table_salt

Asording to the U.S. NAVY the AVERAGE salinity for seawater. is between 37 and 40 PPM (parts per million)  the worlds oceans are constantly getting saltier though.\nsalinity of the ocean is important in calculating sound speed velocity.  which is important for submarines as well as ships that hunt submarines.\n\nWe    HAVE TO   know how SALTY the ocean is.
