Why is the ocean salty?

Ocean salt primarily comes from rocks on land and openings in the seafloor. … Rocks on land are the major source of salts dissolved in seawater. Rainwater that falls on land is slightly acidic so it erodes rocks. This releases ions that are carried away to streams and rivers that eventually feed into the ocean.
