What are other sources of salt ?
In addition to salt brought in by rivers, there are other sources of salt in the ocean. One is underwater volcanoes . as volcanoes erupt on the ocean floor, heat from the volcanic eruption causes minerals to dissolve and salts are released into the water . another continual source of salt is hydrothermal vents in the ocean floor. A hydrothermal vent is an opening in the seafloor from which hot , salty water flows into the ocean. You can think of a hydrothermal vent as a chimney in the ocean floor.
