what keeps seawater salty?

Question

what are the factors that regulate the salinity of seawater?

Answer 1

Influx of trace amounts of salt from rivers and glacial melts, salt derived from submarine volcanism, water temperature, ocean currents, ocean depth, ice cover, and rate of evaporation in seawater.

Answer 2

Certain processes increase the salinity of seawater by removing fresh water. These processes include evaporation and the formation of sea ice (salts do not become part of the ice). Processes that decrease salinity are processes that add fresh water to the ocean, such as precipitation, runoff, and the melting of icebergs and sea ice.

Answer 3

sodium chloride (NaCl) is found in higher concentrations around the shore lines and coastal regions of the planet. this is from the intense evaporation having the least amount of seawater to be dilluted with due to shallow waters.

if you go swimming out past the breakers in the ocean you can easily open your eyes underwater and it not sting a bit. very close to your own bodies concentration of salts. but up near the surf/shallow water line, it can sting like crazy because it is much higher concentration.

Answer 4

As you know, people go to the beach every summer. During many of those months, it is hot. People then start sweating and look at each other and say "Dang it's hot, let's go hop in the ocean and cool off." The sweat on their bodies then is washed into the ocean, replenishing the salt content of the water. (Please don't ask about the Uric acid content of the water.)
