Hydrothermal Vents- Chapters 2, 5, 16
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 10-20⁰C (50-68⁰F)
to 350⁰C (660⁰F).• Mineral particles such as sulfides and
carbonates precipitate to form chimneys.
