Why the sea water is salty
It is an interesting fact that why water in sea or ocean is salty? Where the salt come from? Actually the salt comes from mountain. When rain falls in mountain and river flow through mountain area the water carry too much salt from mountain. The salt regularly stored in sea.Then why the river water is not salty? It is because the concentration of salt in river water is too low then that if the sea. Then how the concentration of salt is greater in ocean? It is because the salt is not stored in instant of time but it takes millions of years. The water carry salt to water and become vapor and again returns through mountain but salt can not vaporize ans stored in the sea. In this way salt going added and added. Similarly a huge amount of other salts present in sea. So sea water is not recommended for direct use.
