Where does the salt come from in the ocean?

Answer 1

Salts in the ocean mostly come from black smokers and white smokers. While it is true that rivers contribute some salt to the oceans the amount is exceedingly small. Also, Lovin' the Lord made a mistake. His statement; "It comes from the rocks and rivers. That's how we know the Earth can't possibly be millions of years old, because the seas would be too salty if they were more than a few thousand years old"; neglects to mention one thing: Oceanic Plate Subduction. As oceanic plates get subducted under continental plates a certain amount of water and pelagic sediments from the accretionary wedge also get subducted. Sodium in ocean water probably converts calcium plagioclase (bytownite or labradorite) into a more sodic plagioclase (andesine or or oligoclase). This process could explain the "Andesite Problem", not that it concerns religious nuts determined to foster Mesopotamian Mythology on Science.

Answer 2

The ocean is salty because most of the rivers and streams which are strewn with rock and plant debris empty into it.The rocks contain many minerals and salt(especially sodium chloride)which dissolve in the water.These are carried to the sea by the rivers.
When these sea waters evaporate due to the heat of the sun,they leave the salt behind.The evaporated water come back to the land again as rain and the rivers again carry this water to sea.As this cycle is repeated, the amount of salt increases(as it is going for millions of years)but the water content remains the same.
If the seas also have an outlet to let out the salt,the oceans water may not be salty.

Answer 3

The salt in sea is made up of weathering and erosion process.... the rocks are broken and the salts from them goes in the ocean....hope that helps ..for more info. use this source! :-))

It comes from the rocks and rivers. That's how we know the Earth can't possibly be millions of years old, because the seas would be too salty if they were more than a few thousand years old.
