Why is the ocean salty and how does it stay that salty with fresh rain water???

Question

Please no links, I would like to know what people think or know already, not what they can research.

Answer 1

Salt is gathered and carried to the ocean by rain water through the river and stream systems in very small amounts over millions of years.Salt is to heavy to evaporate back into the atmosphere with water vapor and it becomes trapped in the ocean.Salt settles toward the ocean floor making the ocean more salty as it gets deeper.Fresh water will flow on the top of salt water at first until it can be mixed together because the salt water is heaver and more dense.

Answer 2

Water is constantly flowing down into the earth's crust, heated up by magma and returned to the ocean. It picks up minerals on the way.

That fresh rainwater is just salty ocean water that's been purified by evaporation, by the way. The salt it used to have is left behind in the ocean. So the ocean would never run out of salt no matter how much of fresh water flowed into it.

Answer 3

The water that falls on or flows into the ocean is for the most part water that was evaporated from the ocean, so it is just recycling its own water. Evaporation leaves the salt behind, so there is no salt being lost there. The salt is carried to the ocean by rivers or dissolved from minerals on the ocean floor. Salt can also be removed from the ocean water by precipitating out as mineral deposits. This has a buffering effect on the salinity level.

Answer 4

simple. minerals from rocks and other elements of the coean bed when react with other substance get decayed and salt is produced. (all chemical reactions, i.e)

waste products from animals an d plants contribute.
submarine volcanoes and earthquake produce gases and molten rocks wen solidified, ----salty reactions.

why it remains sallty? look at the expanse of ocean water, quite a large volume. there would have to be a lot a rain to get the ocean water "fresh". And besides, the reasons for the water being salty are ongoin and rains come in seasons and can never cancel off so much salt water.
