where to the salts in the sea come from?

Answer 1

All the previous answers are wrong. Although some salt comes from continental sources, the salinity of the ocean is controlled by black smokers and white smokers. These features spew out hot water containing ions ("salts") that come from contact with basalt, and transfer much more salt than could ever be accounted for by erosion of land minerals.

Answer 2

i think i have a different answer,if your talking about the pacific ocean which contains "salt water". Basically in Hawaii (which contains a lot of salt water) it starts by the waves crashing on the rocks on the beach (or the volcanic rocks). Then the water on the rocks dries from the sunlight. Apparently the evaporated substance eventually breaks down to small particales and washes back into the sea. The process repeats over and over, cause well the waves can't be controlled so the water is surrounded by almost like a substance from the sea just added elements fromthe rocks.

Answer 3

Rain falls on and flows over the land.
At some point it reaches the sea from which it evaporates and does it over again.
Each time it disolves whatever salt it can.
The soluble salts wind up in the sea.

Answer 4

baSALT is one of the most common igneous rocks, and it's not just a clever name.

The mineralogic structures that make up basalts leave the elements that make salts fairly easy to remove from the rock, including sodium, potassium, chloride, fluoride, and others.

Answer 5

Sodium Feldspars. Most common mineral within the earth. Erosion of them = saltly ocean.

Answer 6

Breakdown of elements in rocks

Answer 7

runoff of rainwater from land picking up Cl and Na and eventually washing into the oceans

Answer 8

Yes it is the breakdowns of elements of rocks but it also is basically sulfur
