Black smokers are hydrothermal vents located on the ocean floor that emit dark plumes of mineral-rich, superheated water. These vents are found in areas where tectonic plates diverge or spread apart, allowing seawater to penetrate into the Earth’s crust. As the water seeps deeper into the crust, it is heated by the high temperatures and pressures found there.
The hot water then rises back up to the ocean floor through fissures in the crust, carrying dissolved minerals and gases with it. When the superheated water meets the cold seawater, the minerals in the water solidify and form chimney-like structures around the vents, which can reach heights of up to 60 meters (200 feet).
The name “black smokers” comes from the dark color of the plumes emitted by the vents, which are caused by the high concentrations of sulfur and other minerals in the water. These vents support unique ecosystems that are not found anywhere else on Earth, including communities of bacteria and other microorganisms that can survive in the extreme conditions around the vents.
