What makes sea water salty?

Answer 1

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.

The 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).

Answer 2

The term "salt" is not used by chemists in exactly the same way that it is used by cooks. For cooking or seasoning purposes we use a chemical called table salt, with the formula NaCl (also known as sodium chloride). However there are many ionic compounds that are considered to be salts by chemists, and these include compounds of sodium, potassium, calcium, and various other metals, combined not only with chlorine but also with iodine, with fluorine, with nitrate radicals, phosphate radicals, and various others. There are a large number of these so I am not going to try to list them all for you. The ocean is salty because of all these salts.

Answer 3

Ok whats in sea water? alot of H2O or water but alot of disolved minerals. ONe of the most common is Iodine. if you have an injury like a scatch or cut it stings when you go in the sea. but it heals fast. that's the iodine in the water, killing the bacteria and alowing the skin to heal without the bacteria. but what is salt.

The salt in ocean or sea water isn't salt. It is infact detected by the number of protons in solution. we call this pH or acidity.

so salt water from the sea is salty because of the slightly acidic pH or number of protons in solution and the effect that weak pH solutions have on minerals like iodine and the way inwhich our taste senses detect these. its not so straight forward

the concentration of Iodine is quite high look at this..

The iodine will eventually cause lots of damage to the human body if you are immersed in the ocean for a long period. Look up USS Indianapolis and the Sailors who escaped to the sea after the Japanese Torpedo attack..

good luck

Well, salt is the remains of sand...and some scientists think that the ocean is salty because the ocean used to sway on the desert. But the ocean moved to the middle of the earth. Now the desert is just sand. The ocean must have collected the salt from the desert.

The ocean water gets salty a number of ways. One way is that all the disposal from our bodies go into the ocean. also, all the ocean animals' .Que sera se boy to le pre to hiji

Because there are a lot of minerals in lakes and rivers and ponds, and they wash down into the ocean water, that makes it a little salty. Then evaporation, evaporates the water to make it really salty.

Oceans are salty because the water that fills them contains dissolved salt, just like the kind we use on our food. The amount of salt in ocean water varies from place to place-depending on the different sources of water nearby-but averages about 3.5 percent. Over the course of millions of years, rivers-flowing over salt-containing rocks-have emptied into the oceans, bringing along dissolved salt particles. In addition, salt has leaked from solid salt-containing rocks directly into the seas. Salt can also enter the oceans from volcanic activity on the sea floor.

-- As a river flows through land, it dissolves salt and other minerals from

the bottom and from its banks.

-- Eventually, the river flows into an ocean or sea, along with the salt and

other minerals dissolved in it.

-- When water evaporates from the ocean or sea, only the H2O evaporates.

The salt and other minerals stay there, in the ocean or sea.

-- The water vapor floats around in the atmosphere, eventually falls as rain,

gathers in a river, and the whole thing starts over again.

So the rivers are continuously carrying more salt and other minerals into

the oceans and seas, and none of it ever leaves. The oceans and seas

are continually becoming more salty and mineral-laden, and have been

for a long time.

Salt in the ocean comes from the rocks on land that rain, which is slightly acidic from the carbon dioxide in the air, falls on and erodes. As the rock breaks down ions are created. These ions are carried away in runoff to streams and rivers and, ultimately, to the ocean. Two of the most abundant ions in seawater are chloride and sodium, which are â??salty.â??

The ocean water is salty because of the sulfurous gases from the volcano underneath the ocean floor. There are more volcano's underneath the ocean floor than what is visible on the ground.

Way back when, the earth had a fair amount of salt in its crust. As the earth aged, water carried this salt into the seas. A lot of time went by. The salt couldn't go anywhere once it was stuck in the ocean. Water evaporates and the water cycle continues, but the salt remained - and remains today. The salinity of the ocean varies fairly widely by depth and by the area under inspection. Ocean currents, rivers dumping fresh water into the ocean.

It is because when the rivers pour water in seas they carry some minerals along with them which contains mostly NaCl(Common Salt) which gives a salty taste to the oceans water. One more reason for it is that the sea bed contains silt which also has Common Salt contained in it.

Rivers are what form the ocean. When rivers flow down to the sea, they pass over rocks and dirt that have salty minerals known as salt. The water carries the salty minerals down into the ocean. That's why the ocean is salty. I hope this answer was helpful! :)

Thank god i learned about this

okay

So,

Since water travels from rivers and lakes, you know

It picks up salt that was formed into with debris.

It flows into the ocean and makes it salty

Since the ocean water evaporates everyday,

It leaves the ocean water saltier and saltier!

The ocean tastes salty because it has a high salt content. Because the ocean has not outlet, the water becomes salty over time because of evaporation.

Oceans get their salt from the many rivers that flow into them. Since the ocean is the last stop for many streams and rivers the salt is continually filling the ocean without an outlet.

Most of the salt in the oceans came from land. Over millions of years, rain, rivers, and streams have washed over rocks containing the compound sodium chloride (NaCl), and carried it into the sea. You may know sodium chloride by its common name: table salt! Some of the salt in the oceans comes from undersea volcanoes and hydrothermal vents. When water evaporates from the surface of the ocean, the salt is left behind. After millions of years, the oceans have developed a noticeably salty taste.

The Earth is 4.5 billion years old and in the first billion years, oceans formed and became salty with a salinity that has not change greatly in the last three billion years.

Salt Source:

Salt is continually supplied to our oceans as the result of of minerals leaching and dissolving from the solid earth. The major portion of new salt comes from rivers, while a good quantity of the salts are dissolved from rocks and sediments below the ocean floor, through volcanic vents. The weather is also responsible for some addition, to a minor degree, as the rain deposits mineral particles into the oceans picked up as dust in the air.

Water Cycle:

The sun's heat distills or vaporizes almost pure water from the surface of the sea, leaving the salts and minerals behind. The water returns to the ocean, via rivers or glaciers fed by precipitation, to wash down more salts. This process is part of the continual exchange of water between the Earth and the atmosphere that is called the hydrological or water cycle.

Salt Cycle:

The ocean has a way of removing salt by geologic processes which takes salt water down into the ocean crust and returns water with most of the salt left in the crust. These processes are still the subject of scientific study with specific detailed mechanisms for removing the salt still being debated. Though the mechanism requires refinement, we know there is roughly that same amount of salt removed as there is added and the puzzle of why the ocean do not get saltier has mostly been answered.

Salts from rocks in the rivers are washed into the ocean.

It has or had minerals that formed before the time of dinosaurs. So the minerals produced salt and viola! salty seas.

If freash water flows out to the sea, why is the sea still salty? The magnesium, sulfate, calcium, and potassium make up 99 percentof the dissovled solids in the sea.

The runoff water in the rivers carry with it minute amount of salts which collectively build up the elevated content found in the ocean.

Answer 4

-- As a river flows through land, it dissolves salt and other minerals from

the bottom and from its banks.

-- Eventually, the river flows into an ocean or sea, along with the salt and

other minerals dissolved in it.

-- When water evaporates from the ocean or sea, only the H2O evaporates.

The salt and other minerals stay there, in the ocean or sea.

-- The water vapor floats around in the atmosphere, eventually falls as rain,

So the rivers are continuously carrying more salt and other minerals into

the oceans and seas, and none of it ever leaves. The oceans and seas

Answer 5

Salt made its way into sea water by being dissolved and carried there in solution. It is probably inaccurate to say that salt forms in sea water.

Answer 6

salt, and lots of it

Answer 7

salt.
