Sea water is water in or from the sea. Sea water is flowing. For human beings, the amount of water available is unlimited. Seawater is a real liquid mineral, with an average of 35.7 million tons of minerals per cubic kilometer of seawater. 80% of the more than 100 elements known in the world can be found in seawater. Why is the taste of sea water salty? Follow my steps to find out.
Why is the taste of sea water salty?
There are two kinds of cognition about the source of salt content in seawater.
The first is water circulation.
Under the sunlight, the water in the ocean evaporates continuously and gradually becomes water vapor. It rises into the air, meets the lower temperature air, condenses into rain, and falls on the ground again. The rain washes the soil and soil, and brings the soluble substances into the rivers. The rivers flow into the sea, and the salt substances also enter the ocean. Because salt cannot evaporate, after millions of years of accumulation, the salt content in the ocean continues to increase, and the sea water becomes salty.
The second view is that the soluble salts on the surface of the earth's crust are dissolved by seawater and increase the salt content. Where the earth was formed, the earth's crust was very weak, volcanic eruptions were frequent, and a large number of minerals were ejected from the earth's surface, and then gradually collected into the primitive ocean with the rain. As the soluble salts in minerals are continuously dissolved by seawater, the seawater gradually becomes salty. In particular, the fault heat accumulation reaction at the submarine large fault zone makes the salt content of seawater hundreds of times higher than that of rivers.
Why is the sea blue?
One is similar to the sky, because the wavelength of electromagnetic waves reflected from the sea just represents the blue range
The second color is defined by people. After the eyes receive a specific range of electromagnetic waves, the way to distinguish them is color, that is, the wavelength of electromagnetic waves reflected by seawater corresponds to blue in the color table of the brain to distinguish different wavelengths
