Instead, bacteria and archaea use a process called chemosynthesis to convert minerals and other chemicals in the water into energy.
Why are hydrothermal vents extreme environments?Hydrothermal vents are naturally forming structures found in the ocean. They usually occur on divergent plate boundaries, where tectonic plates are moving apart. The vents expel a fluid that was heated to extreme temperatures when seeping through the Earth's crust from the ocean.
What are hydrothermal vents and why are they important?Hydrothermal vents act as natural plumbing systems that transport heat and chemicals from the interior of the Earth and that help regulate global ocean chemistry. In the process, they accumulate vast amounts of potentially valuable minerals on the seafloor.
What causes hydrothermal vents?Hydrothermal vents are the result of seawater percolating down through fissures in the ocean crust in the vicinity of spreading centers or subduction zones (places on Earth where two tectonic plates move away or towards one another). The cold seawater is heated by hot magma and reemerges to form the vents.
