Actually saltiness in sea water comes from the mainland, the chronology here ... In the event of rain on the mainland water will seep into the soil and little by little will come out again through the river - the river and eventually reach the sea. Well on the way towards the sea to the mainland also bring water from salt - mineral salt so filled with sea salt - mineral salt.
We know the sea has a surface that is so widespread that it is becoming one of the evaporation factor is large enough, when seawater evaporates just H20 (water) are salts of mineral salts remain with water lauu, so that sea water tastes ation. seawater salinity levels is influenced by temperature, usually the more heat the area increasingly salty seawater. then why the water in the lake was not when the water is too salty from the mainland? The answer is because the surface of the lake water is not wide enough so that evaporation is not so great, that the water that evaporates water into the lake still balance mineral resources are very limited and different from the marine mineral resources from around the world into one.
The sea water is water from the sea or ocean. seawater has a salinity average - average 3.5%. This means that the 2.5 liter (2500 ml) of sea water there are 60 grams of salt (mainly, but not entirely, salt / NaCl).
Although most of the seawater in the world has a salinity of about 3.5%, seawater is also different salt content. Most freshwater is in the east of the Gulf of Finland and in the northern Gulf of Bothnia, both part of the Baltic Sea. The most salty is the Red Sea, where high temperatures and limited circulation make high evaporation and little water input from rivers. salinity in some lakes may be higher again.
Seawater has a salinity because the earth is filled with mineral salts contained in rocks and soil. For example, sodium, potassium, calcium, etc. When the river flows into the sea, bringing salt water proficiency level. Sea waves hitting the beach also can produce salt from rocks - rocks. Over time becomes salty as sea water contains a lot of salt.
WHY ARE COLORED BLUE SEA?
There are two main optical processes in sea water, and solute or suspended in seawater, while interacting with the light coming from the sun. These two processes are absorption (absorption) and scattering (scattering). In the atmosphere, the main reason that the sky is blue is caused by light scattering at sea, water main way to interact is with the absorption of light, water absorbs red light, and to a lesser extent, water also absorbs red light, and to a smaller degree remdah, water well absorbs light yellow and green, the color can cause fluctuations depending on the depth and place. The color blue is the color most absorbed by the water, so the water appears blue. In short, the deeper depths of the ocean, the more he is bluish.
The above diagram shows the depth of light that will penetrate in the sea water. Due to the strong absorption of light in the red, making it disappear, and blue light continues to penetrate into the. From the diagram is also the reason why the water in the bathtub is white, in because of all the light is still absorbed by the water so as to make the color appear white. Meanwhile, when the sun begins to set and rise, sea water will appear red in a surface due to the light absorption.
The different colors in the sea, rivers and lakes are also caused by the plants that live in basically like algae found in the Red Sea, and tercwa sediment in the water. like the brown color is terbwa sediment from the river, so as to make the color appear cloudy.
