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.
