Why are oceans salty?
Salt in the sea, or ocean salinity, is mainly caused by rain washing mineral ions from the land into water. Carbon dioxide in the air dissolves into rainwater, making it slightly acidic. Isolated bodies of water can become extra salty, or hypersaline, through evaporation. The Dead Sea is an example of this.
Who named the oceans?
