Salt in the sea comes from erosion that is caused by water, and rivers are responsible for carrying the dissolved salts to the oceans. Lack of a few processes in the sea can be a reason for the salt to increase. Fortunately, but there are many processes, known as salt sinks, that help to remove salt from oceans at precisely the same speed as they get added.
How do the salts get removed from the oceans
One of the significant sinks is water evaporating. Once the evaporation of seawater happens, there’s a rise in salt concentration. But how does that remove the salt content from the sea? This occurs when water becomes supersaturated in some places, and they are not able to keep all the dissolved salt. This further results in sediments that later become sedimentary rocks.
The second sink, spray’s seawater, back onto the land with the help of wind, where the water evaporates and leaves salt deposits behind. The other sinks depend on some chemical processes.
Sea Life also helps in removing salt from the ocean. Many animals extract the salt from the water in the form of poop. They get deployed onto the ocean floor and further become part of the sediment layer there. Same as evaporite minerals, they eventually become a part of sedimentary rocks.
This is the process of how salt gets removed from the ocean. Now coming back to the question that does the sea continue to get saltier? The answer is, most probably, NO. The salts sink removes the same amount of salt from the sea. So it kind of balances it out and the salt quantity remains the same in the sea.
There’s a probability of it changing because of global warming, but till now they are not saltier than before.
