Why Are Seas and Oceans Salty?

This has occurred since the emergence of organic organisms (ie, in living things) of the earth. They urinate - right now. They will pee.

In science, there is a concept of catchment catchment. In other words, even if we go into the lake "enter the land" without looking into rivers and streams, urine falls into the groundwater area, later becomes a river, and finally to the ocean. It is also clear that the urine of toilets (cities and villages) also flows to the sea and the sea.

Therefore, from a chemical point of view it is possible to say jokingly that sea and ocean water is not water but urine - "homeopathic dilution"

Chemical water from the liquid gradually evaporates, but salt still exists. Therefore, salt concentrations in the oceans and the oceans are slowly increasing.

The main salt that gives salty taste to seawater is sodium chloride. This can be extracted from sea salt sediment (including ancient dry salt mine called rock salt) or extracted during seawater desalination. We will first use the salt obtained by these methods, after industrial refining - for the production of foods

But salt water is not just salt present in urine. Sea water also contains soluble natural minerals and plant substances such as algae, bacteria, decaying corpse, feces, meteorites, and other cosmic bodies falling to the earth. The list may be expanded by herbicides, chemical fertilizers, other industrial derivatives (including those wastes).

Sea water usually contains a complete set of chemical elements called trace elements. Their intake of our organisms is very important to maintain health. Therefore, add the appropriate amount of sea water to the food - this is correct.

However, it is best not to drink raw seawater diluted with fresh water. It contains microorganisms, some of which are pathogenic

Remember that in seawater there are many chemical interactions among the elements in it.

In addition, bacteria play an important role in changing the chemical composition of seawater.

The sea, the sea of ​​the world, or a simple ocean is over 70% of the salt water covering the surface of the earth. It relaxes the climate of the planet and plays an important role in water circulation, carbon cycle and nitrogen circulation. It has been traveled and explored since long ago and scientific research in marine oceanography generally ranged from the voyage of Captain James Cook to the Pacific exploration from 1768 to 1779. The word "ocean" is also used to mean a smaller, partially inland oceanic part.

The sea is a large salt water surrounded by the sea. To put it more broadly, the "sea" is an interconnected system of earth's salt and salty oceans, coming from various sources like rain and atmospheric rainfall. It is considered a global ocean or a few ocean boundaries. The oceans calm the earth's climate and play an important role in water cycle, carbon cycle and nitrogen cycle. It also focuses on the phenomenon of rainfall distribution. Because the wind that brings water from the ocean brings rain to nearby lands. Modern scientific research oceans and oceanography came widely after the exploration of British challengers of the 1870s. The sea is usually divided into five large sea areas. The International Hydrology Institute is called the four oceans (Atlantic, Pacific, India, Arctic) and the second stage like the Mediterranean is known as the ocean.

Water is an important resource for every life. You can find water in many parts of the earth: in the sea, rivers, lakes, ponds ... water has three quarters of the earth's surface. Saltwater is called sea water, and the water in rivers and lakes is sweet, but these areas are areas that meet salt water and fresh rivers, so the resulting mixed water is called brackish water. Animals living in the water are called aquatic animals such as aquatic animals. Fish, algae or whales. Is the sea and the freshwater ocean inland water (freshwater)? There are still plenty of water in the body, more than half of all are presumed to be water. Fruits, vegetables, and many foods contain plenty of water.
