WebHydrothermal Floor Vents Christian Kaiser Hydrothermal vents are found near mid ocean ridges, divergent plate boundaries, where tectonic plates are moving apart. They are usually more than 2000 meters below the ocean's surface. These vents are formed when lava spews from an underground volcano and mixes with the cold ocean water. The cold … Web1 jan. 2015 · This discovery began more than two decades of intensive exploration of the oceans for additional evidence of seafloor hydrothermal activity.
