how do the sea water contains salt?

Answer 1

Here is a fairly good explaination:

"Scientific theories behind the origins of sea salt started with Sir Edmond Halley in 1715, who proposed that salt and other minerals were carried into the sea by rivers, having been leached out of the ground by rainfall runoff. Upon reaching the ocean, these salts would be retained and concentrated as the process of evaporation (see Hydrologic cycle) removed the water. Halley noted that of the small number of lakes in the world without ocean outlets (such as the Dead Sea and the Caspian Sea, see endorheic basin), most have high salt content. Halley termed this process "continental weathering".

Halley's theory is partly correct. In addition, sodium was leached out of the ocean floor when the oceans first formed. The presence of the other dominant ion of salt, chloride, results from "outgassing" of chloride (as hydrochloric acid) with other gases from Earth's interior via volcanos and hydrothermal vents. The sodium and chloride ions subsequently became the most abundant constituents of sea salt.

Ocean salinity has been stable for billions of years, most likely as a consequence of a chemical/tectonic system which removes as much salt as is deposited; for instance, sodium and chloride sinks include evaporite deposits, pore water burial, and reactions with seafloor basalts[6] Since the ocean's creation, sodium is no longer leached out of the ocean floor, but instead is captured in sedimentary layers covering the bed of the ocean. One theory is that plate tectonics result in salt being forced under the continental land masses, where it is again slowly leached to the surface."

Answer 2

The Oceans are a salt sink. Minerals are extracted from continental rocks by the various types of errosion, carried to the seas by rivers and deposited. Some mineral salts remain in solution while others are locked up in sediments. This is why the salinity of the Oceans doesn't change over time, as one would normally expect them to become saltier and saltier.

Answer 3

I think patois is close to the answer but she/he?still short of the exact answer or explanation. As a GEOLOGIST I could confidently say that constant replinishment of salt is aptly done by the silent effluence of lava material along the plate boundries that criss cross the ocean floor where the more reactive salt forming elements readily go into solution with abundant water supply offered by the ocean water.At same time the what patois is telling is also a matter of fact that contributes to salt content of ocean.

Answer 4

Years and years ago in a far far country a king ordered to distroy all the salts in his country. The princess was so sad to hear this. So she ask the neighbouring country prince to help her to save the salt from this ferocious king.The price took the salt in 100s of ships and carried them to the near by continent .But the king however got the message. He came with his military and destroyed all the ships and the drowned the ships.And that day onwards the sea has salt in it.

Answer 5

To answer your question, we should go to the Earth's origin. When Earth originated, it is very hot and gradually, it cooled and atmosphere formed. It began to rain. For many years it continued to rain and the water which fall on the soil began to absorb the salts which are present in the earth. In summer, some of the water evaporated and salt remained in the remaining water. Thus concentration of salt increased and came to the present position. Thus seas are so salty....

Answer 6

The sea ends at beaches of islands. The beaches contain sand, which s the unpurified form of salt. As the sand dissolves into the water, they become salt.

Answer 7

All water bodies, lakes, rivers, seas etc. contain salt.These rivers pour into the sea taking all that salt.There, the water is evaporated and salt is left behind.Overtime, this salt is colected in large quantities and makes it salty.

Answer 8

Salt that is produced by the evaporation of sea water and that contains sodium chloride and trace elements such as sulfur, magnesium, zinc, potassium, calcium, and iron.

Answer 9

from the dirt, the bottom of the oceans would be land if there was no water there. salt if water soluable, which means that salt will dissolve in the water. only by osmosis filtration or boiling the water to steam will separate the solution
