WebNov 10, 2024 · In the process, the fluids become hotter and more acidic, causing them to leach metals such as iron, zinc, copper, lead, and cobalt from the surrounding rocks. The heated fluids rise back to the surface through openings in the seafloor, known as hydrothermal vents. WebHot or molten rock (magma) beneath the ocean floor is the engine that drives hydrothermal vents. It heats the hydrothermal fluids, causing them to move upwards through the crust. Therefore, hydrothermal vents are found only in areas where there is volcanic activity and the magma is close enough to the surface to heat the fluids.
