Where did the salt in the ocean come from?

Salt in the ocean comes from the land. The elements that make up salts, such as chlorine and sodium, started out in rocks. Water and acids eroded the rocks, and rivers carried the elements into the sea. The oceans usually contain 35 parts of salts for every 1000 parts of sea water. This is lower in some places where there is a lot of fresh water coming into the ocean. It is higher where the Sun is very strong and evaporates more of the water. When all the water is gone, the salts are left behind as solid, white crystals.

Water is regularly occurring because of the fact the familiar solvent. As rain hits the lands surfaces it melts the "salts" are dissolved and finally run into the seas and oceans. Over the millennium the salts, halite, etc. have been outfitted up adequate so as that the oceans easily grew to alter into salty.

Rain falls on the earth and dissolves salt from rocks on the way down to the ocean.

The water in the ocean evaporates leaving the salt behind. The water in the air condenses as rain and starts the process all over again. Leaving the oceans to fill up with salt.

Most of the salt in the oceans came from land. Over millions of years, rain, rivers, and streams have washed over rocks containing the compound sodium chloride (NaCl), and carried it into the sea. You may know sodium chloride by its common name: table salt! Some of the salt in the oceans comes from undersea volcanoes and hydrothermal vents. When water evaporates from the surface of the ocean, the salt is left behind. After millions of years, the oceans have developed a noticeably salty taste.

Different bodies of water have different amounts of salt mixed in, or different salinities. Salinity is expressed by the amount of salt found in 1,000 grams of water. Therefore, if we have 1 gram of salt and 1,000 grams of water, the salinity is 1 part per thousand, or 1 ppt.

The average ocean salinity is 35 ppt. This number varies between about 32 and 37 ppt. Rainfall, evaporation, river runoff, and ice formation cause the variations. For example, the Black Sea is so diluted by river runoff, its average salinity is only 16 ppt.

Erosion in the ocean as a result of abrasion etc cause the material in the ocean to be eroded such as the rocks in the ocean over time the rock particles become smaller and smaller appearing like salt.
