Ever wonder why the salty sea water, where the salty taste? Is it because the fish sweat? The answer of course is ridiculous. We should know the answer scientifically. Hopefully this article can discuss curiosity about the source of salinity of sea water.
Sea water has an average salinity of 3.5%. This means that in 1 liter (1000 mL) contained 35 grams of sea salt (mainly, but not entirely, salt / NaCl).

Although most of the sea water in the world has a salinity of about 3.5%, sea water is also different salt content. The most bargaining is in the eastern Gulf of Finland and in the northern Gulf of Bothnia, both part of the Baltic Sea. The most salt is in the Red Sea, where high temperatures and limited circulation makes high evaporation and little input of water from the rivers.
Sources saltiness
Sea water has a salinity because the earth is filled with mineral salts contained in rocks and soil. For example sodium, potassium, calcium, etc.. If the river water flowing into the ocean, the water carrying salts.
In the event of rain on the land, the water will seep into the ground and little by little will come out again through the dam rivers eventually reach the sea. Well on the way to the sea when the water from the mainland also carry mineral salts so that the sea was filled mineral salts.
We know the sea surface has a very wide so it is becoming one of the evaporation factor is large enough, at the time of the evaporating sea water evaporates is H2O (water) are mineral salts remain with sea water, that's salty sea water so as.
Levels of salinity of sea water is influenced by the temperature, the more heat is usually the area increasingly salty seawater.
Why not salty lake?
Lake water level is not sufficiently broad so as evaporation is not so great, that the water that evaporates with the water coming into the lake and the balance is still very limited mineral resources with different marine mineral resources from around the world into one.
