To learn more about this topic, start your googling with these keywords:

• Salt: chemical compounds made of positively- and negatively-charged particles called “ions” like sodium and chloride
• Convection current: the movement of fluid, like water, due to a difference in temperature and/or density
• Hydrothermal vent: a fissure on the seafloor that takes in dense ocean water and discharges water heated by volcanic activity below the seafloor.
