Wher does from huge Chlorine (NaCl) come into Sea water, Wat is the source of Chlorin?

Question

There r only few known Minerlas (probably only 2), it cannot give rise to such an huge amount of Chlorine in the sea water. Then where from these many amount of Chlorine in NaCl came from???

Answer 1

The NaCl in sea water comes from the land masses. It is leached out of the earth where it exists as a mineral (halite). Because it is very soluble, a large quantity is dissolved by rainwater, more than other minerals. Over the years, minerals are added to the seas by rivers carrying dissolved salts from the ground. Sea water is evaporated eventually (the hydrologic cycle, see http://en.wikipedia.org/wiki/Hydrologic_cycle, but the minerals stay behind. So their concentration builds up slowly. Over thousands of years, the salt concentration gets to what it is today. It is still rising. But the salt came from the land.

Answer 2

EROSION, to put it simply. Over billions of years the rivers erode the banks of the landmass that they are on, carrying dissolved ions of whatever particular type of rock they are eroding. As the water cycle takes place, it evaporates the water and leaves the minerals behind, explaining the large mass of sodium in the oceans. The only reason sodium is so abundunt in the ocean is because it is so abundant on land. Many minerals are composed of sodium and break down into sodium and other products when they erode. It's chemical properties also help it be transported to the oceans and allow it to remain a free ion in solution (Na+) wheras other elements may re-deposit themselves somewhere else or combine with some other element.

Answer 3

Normal table salt is NaCl or sodium chloride.

Answer 4

huge blouder in the sea that contain minerals, include NaCI,
