Hydrothermal Vent
  • Hydrothermal vent- a deep-sea hot spring where
    heated seawater forces its way up through the
    crust.
  • Discovered rich communities in 1977.
  • Temperatures range from 10-20C (50-68F) to
    350C (660F).
  • Mineral particles such as sulfides and carbonates
    precipitate to form chimneys.
