Why Does the Ocean Have Salt?

Answer

Water in the oceans is salty because oceans have been around for a very long time. As a result some of the salts were added into the water at a time when lava and gases were spewing from augmented volcanic activity. Carbon dioxide dissolved in water from the atmosphere creates a weak carbonic acid that dissolves minerals. These minerals form ions when they dissolve, making the water salty. The salt gets left behind while water evaporates from the ocean. It can as well be as a result of rivers that drain into them bringing in additional ions from a rock that was eroded by rainwater and streams.

The oceans have salt because the rivers that flow into them pick up salt from minerals and rocks. All this salt goes into the ocean and when the ocean water evaporates the salt does not therefore the ocean stays salty. Another reason oceans 'may' have salt is for the Earth to have a better taste. Just like humans like putting salt on food for taste.
