Explanations: answer key for all 10 questions
- Q1: What is a hydrothermal vent?
Answer: A seafloor opening releasing heated, mineral-rich water
Seawater is heated by magma below.
- Q2: Where are most vents found?
Answer: Along mid-ocean ridges
Plates spread apart there.
- Q3: Where were vent communities first discovered in 1977?
Answer: Galápagos Rift
Scientists used the submersible Alvin.
- Q4: What gives black smokers their dark color?
Answer: Metal sulfide minerals
Minerals form chimneys.
- Q5: How hot can vent water get?
Answer: Over 400 °C
High pressure keeps it liquid.
- Q6: How do vent bacteria make food?
Answer: Chemosynthesis
They use chemicals like hydrogen sulfide.
- Q7: Which animal grows up to about 2 meters at vents?
Answer: Giant tube worm
It has no mouth or gut.
- Q8: What is Lost City?
Answer: A vent field with white carbonate towers
It was found in 2000.
- Q9: Why are vents linked to the origin of life?
Answer: They provide energy and chemicals life may have used
It is a leading hypothesis.
- Q10: Which vent animal has a shell plated with iron?
Answer: Scaly-foot snail
Its iron armor is unique.
Hydrothermal Vents Challenge – Life Without Sunlight
Hydrothermal vents are openings in the seafloor where seawater, heated by magma below, gushes out loaded with minerals. Most are found along mid-ocean ridges where tectonic plates pull apart. Black smokers build chimneys from metal sulfides.
In 1977, scientists in the submersible Alvin found thriving communities at vents on the Galápagos Rift. Instead of sunlight, bacteria use chemicals in a process called chemosynthesis. Giant tube worms, clams, shrimp and crabs depend on them.
Vents changed ideas about where life can exist and may hint at how life began on Earth or could exist on icy moons. Their mineral deposits attract mining interest, raising concerns about protecting these unique ecosystems.
