River: River water is sweet so we can drink it whereas sea water is salty so we cannot drink it.
If the water of all the oceans was sweet instead of salty, there would be no shortage of water in the world. According to the US National Oceanic and Atmospheric Administration, if all the salt from all the oceans is taken out and spread on the land, its layer will become very high.
Let us first know why the water of rivers is sweet, then let us tell you that rivers contain water from springs, as well as rain water and because rivers flow from far away, water is also found in it along with other substances of nature, which dissolve in it.
Which are in abundance. Therefore the water of rivers is not only sweet but is also considered clean. The amount of salt in the sea is high.
This salt is found in the sea from rivers only. Actually, there can be two reasons for salt being found in the sea. The first is that most of the salt in the sea comes from rivers. It is said that rainwater is slightly acidic, while when it falls on rocks on the ground, it destroys them and the iron formed from it dissolves in the sea through rivers. Due to this, the sea water is becoming salty.
Apart from this, the most abundant elements present in sea water are chlorine and sodium. Together, these two make up 85 percent of the ions dissolved in the sea. After this, magnesium and sulphate make up 10 percent. Due to this, the amount of residual ions in it is very less. That is why we always find sea water salty and not drinkable.
