Hydrothermal vents are openings in the seafloor that release hot, mineral-rich water due to volcanic activity. Found along mid-ocean ridges, these vents support unique ecosystems. Organisms near vents adapt to extreme conditions, relying on chemosynthesis for energy. Studying hydrothermal vents helps scientists understand Earth's geology, chemistry, and the possibility of life in extreme environments. #ocean #ecosystem #geothermal
