How do black smokers create life?
Black smokers support ecosystems of unique life forms. The smokers eject sulfides that feed bacteria at the bottom of an unusual food chain that exists only in the inky blackness of the ocean floor. Seawater descends through fractures in the oceanic crust flanking spreading ridges.
What are black smokers the result of?
“Black smokers” are chimneys formed from deposits of iron sulfide, which is black. “White smokers” are chimneys formed from deposits of barium, calcium, and silicon, which are white. Underwater volcanoes at spreading ridges and convergent plate boundaries produce hot springs known as hydrothermal vents.
What is significant about black smokers for biology?
Although life is very sparse at these depths, black smokers are the centers of entire ecosystems. Sunlight is nonexistent, so many organisms, such as archaea and extremophiles, convert the heat, methane, and sulfur compounds provided by black smokers into energy through a process called chemosynthesis.
What kind of life is found around black smokers?
Types of organisms
Organisms found near black smokers are those such as 3-foot-long tubeworms, shrimps, crab, and anemone. The biggest discovery of these vents was that these organisms get their energy from the planet and not from a star.
What are black smokers made out of?
Metal sulfides and oxides (zinc sulfide, iron sulfide, copper-iron sulfide, manganese oxide, and iron oxide) precipitate from the vent fluids as fine-grained particles, most of which form a plume of “smoke.” Because bottom seawater is denser than the mix of seawater and hydrothermal fluid in the plume, the plume rises …
Is the Pompeii worm an animal?
The Pompeii worm (Alvinella pompejana) is an extremophile—an animal that thrives under extreme conditions.
Where do black smoker bacteria live?
Most bacteria and archaea cannot survive in the superheated hydrothermal fluids of the chimneys or “black smokers.” But hydrothermal microorganisms are able to thrive just outside the hottest waters, in the temperature gradients that form between the hot venting fluid and cold seawater.
How are white smokers different?
Compared to black smokers, white smokers usually emit cooler plumes and form smaller chimneys. Vents with even cooler, weaker flows are often called seeps. They appear to shimmer because of differences in water temperatures or bubble because of the presence of gases, like carbon dioxide.
Why is it so unusual that life is found near these vents?
The floor of the deep ocean is almost devoid of life, because little food can be found there. But around hydrothermal vents, life is abundant because food is abundant. Hot, mineral-rich fluids supply nutrient chemicals.
How hot do black smokers get?
Existing at a depth of more than 2000 m, black smokers emitted a strong flow of black, smoky water, superheated to over 400°C (750°F).
What is the PH of a black smoker?
Black smokers are very acidic typically with a ph. of 2 (around that of vinegar). A black smoker is a type of vent found at depths typically below 3000m that emit a cloud or black material high in sulphates.
What are black smokers and what do they represent?
Definition of black smoker
: a vent in a geologically active region of the sea floor from which issues superheated water laden with minerals (such as sulfide precipitates) also : a rock chimney covering such a vent.
How hot is a white smoker?
White smoker fluid is usually cooler (only 250-300°C!) and flows more slowly than the black smoker fluid. The chimneys generally are smaller as well. The white color comes from minerals that form when the fluid exits the chimney and mixes with seawater.
What is the deepest spot in all the ocean?
The deepest part of the ocean is called the Challenger Deep and is located beneath the western Pacific Ocean in the southern end of the Mariana Trench, which runs several hundred kilometers southwest of the U.S. territorial island of Guam. Challenger Deep is approximately 10,935 meters (35,876 feet) deep.
How do the smoker chimneys grow?
Massive amounts of sulfide minerals (metal-bearing sulfur compounds), such as pyrite, chalcopyrite, and sphalerite, along with silica and the calcium sulfate mineral anhydrite, precipitate out and eventually form towering, chimney-like structures.
What is the ultimate food source in the vent community?
Chemosynthetic bacteria are the primary producers and form the base of vent food webs. All vent animals ultimately depend on the bacteria for food.
What is the source of energy in the black smoker ecosystem?
They are unusual in that the main source of energy is not light from the sun but the heat from molten rock. At certain points, sea water penetrates cracks in the ocean floor and comes into contact with the lava produced by active volcanoes.
What eats Pompeii worm?
These bacteria use a process called chemosynthesis to produce sugar from the chemicals spewed out by hydrothermal vents. Predators: Many of the crabs, lobsters, and other creatures can feed on the Blind Shrimp. Predators: Large fish, octopus, blind crabs and squids.
What are black smokers and why are they important quizlet?
Black smokers form when sea water seeps into the cracks of the earths crust toward the hot rocks below. Then the hot rocks heat the water up to extreme temperatures while this happens the water slowly collects minerals from the rocks surrounding it. Eventually the water shots back up through the earths crust.
What are vent fields?
(Gun.) a flat raised surface around a vent.
Does the Pompeii worm swim?

What eats giant tube worms?
Few deep sea creatures such as deep sea crabs and shrimps, large brown mussels and giant clams are predators of giant tube worms (they feed on plumes).
What is the difference between a black and a white smoker?
White smoke can often mean material is off-gassing moisture and water vapor, meaning the fire is just starting to consume material. White smoke can also indicate light and flashy fuels such as grass or twigs. Thick, black smoke indicates heavy fuels that are not being fully consumed.
What determines a black smoker what chemicals are released?
The black “smoke” is caused the presence of iron and sulfur, which combine to become iron monosulfide, which has a black color. When the iron monosulfide solidifies, it created the black chimneys. “White smokers” are the cooler cousins of black smokers. These vents release cooler water then “black smokers”.
What are white smokers in the ocean?
A white smoker is a hydrothermal vent emitting alkaline high-pH hydrothermal fluid on the ocean floor. These fluids are cooler (260–300°C) than those emitted by black smokers (360°C) and are sited away, or “off-axis,” from the mid-ocean ridges.
What are white smokers formed of?
Cooler vents produce “white smokers” that are dominated by deposits of calcium-rich minerals, including anhydrite gypsum (CaSO4) and calcite (CaCO3). Minerals in ocean crustal rocks are rich in calcium, which dissolves easily on cold seawater.
How hot was the water coming out of the black smokers?
As the hot water — which can reach temperatures of over 700 degrees Fahrenheit — escapes from the vents and comes in contact with the near-freezing water of the ocean bottom, the metals quickly rain out of their solution.
What are ocean ridges?
Mid-ocean ridges occur along divergent plate boundaries, where new ocean floor is created as the Earth’s tectonic plates spread apart. As the plates separate, molten rock rises to the seafloor, producing enormous volcanic eruptions of basalt.
How do tube worms eat?
Tubeworms do not eat. They have neither a mouth nor a stomach. Instead, billions of symbiotic bacteria living inside the tubeworms produce sugars from carbon dioxide, hydrogen sulfide, and oxygen. The tubeworms use some of these sugars as food.
Why do we believe that life on Earth may have formed near hydrothermal vents?
Summary: By creating protocells in hot, alkaline seawater, a research team has added to evidence that the origin of life could have been in deep-sea hydrothermal vents rather than shallow pools.
Why are hydrothermal vents black smokers useful in the study of early life on Earth?
Inspired by these findings, scientists later proposed that hydrothermal vents provided an ideal environment with all the ingredients needed for microbial life to emerge on early Earth.
Where are most vents located?
It heats the hydrothermal fluids, causing them to move upwards through the crust. Therefore, hydrothermal vents are found only in areas where there is volcanic activity and the magma is close enough to the surface to heat the fluids. Most of the vents scientists have discovered are along the Mid-Ocean Ridge.
How hot are geothermal vents?
Life at hydrothermal vents
Initially the temperature of the fluid released from hydrothermal vents is extreme – it can reach over 400°C. But despite the scalding heat, the environment around the vents is habitable for a range of animals.
Why is the Lost City so hot?
The water venting at Lost City is generally 200°F. The fluids do not get as hot as the black smokers because it is not heated by magma; rather, the heat comes from serpentinization, a chemical reaction between seawater and mantle rock.
Did life originate in hydrothermal vents?
By creating protocells in hot, alkaline seawater, a UCL-led research team has added to evidence that the origin of life could have been in deep-sea hydrothermal vents rather than shallow pools.
What are black smokers at mid-ocean ridges answer choices?
Black smokers are the largest type of ocean vent, and eject the hottest fluids. Vent fluids spew out of tall chimneys at rates of up to 5 meters per second (16 feet per second). The “smoke” blown from black smokers is a dense cloud of particles, mostly metals such as iron and copper.
Has anyone been to the Mariana Trench?
While thousands of climbers have successfully scaled Mount Everest, the highest point on Earth, only two people have descended to the planet’s deepest point, the Challenger Deep in the Pacific Ocean’s Mariana Trench.
Who has been to the Mariana Trench?
On 23 January 1960, two explorers, US navy lieutenant Don Walsh and Swiss engineer Jacques Piccard, became the first people to dive 11km (seven miles) to the bottom of the Mariana Trench. As a new wave of adventurers gear up to repeat the epic journey, Don Walsh tells the BBC about their remarkable deep-sea feat.
Are there monsters in the Mariana Trench?
Despite its immense distance from everywhere else, life seems to be abundant in the Trench. Recent expeditions have found myriad creatures living out their lives at the bottom of the sea-floor. Xenophyophores, amphipods, and holothurians (not the names of alien species, I promise) all call the trench home.
Why are black smokers important?
Although life is very sparse at these depths, black smokers are the centers of entire ecosystems. Sunlight is nonexistent, so many organisms, such as archaea and extremophiles, convert the heat, methane, and sulfur compounds provided by black smokers into energy through a process called chemosynthesis.
How are black smokers formed?
The particles are predominantly very fine-grained sulfide minerals formed when the hot hydrothermal fluids mix with near-freezing seawater. These minerals solidify as they cool, forming chimney-like structures. “Black smokers” are chimneys formed from deposits of iron sulfide, which is black.
How do animals survive in hydrothermal vents?
Organisms that live around hydrothermal vents don’t rely on sunlight and photosynthesis. Instead, bacteria and archaea use a process called chemosynthesis to convert minerals and other chemicals in the water into energy.
Which hydrothermal vent has the highest temperature?
Lying more than 3,800 meters (12,500 feet) below the surface, the Pescadero Basin vents are the deepest high-temperature hydrothermal vents ever observed in or around the Pacific Ocean. They are also the only vents in the Pacific known to emit superheated fluids rich in both carbonate minerals and hydrocarbons.
What color is the giant deep sea Tubeworm?
Perhaps the most noticeable characteristic of these worms is their bright red plume. This is a specialized organ used for exchanging compounds such as oxygen, carbon dioxide, and hydrogen sulphide with the seawater. The bright red color comes from the presence of large amounts of hemoglobin (blood).
Does chemosynthesis require oxygen?
Chemosynthesis may be coupled to both aerobic and anaerobic respiration. Aerobic chemosynthesis depends on oxygen, which ultimately originates from photosynthetic processes occurring in the photic zone.
What kind of life is found around black smokers?
Types of organisms
Organisms found near black smokers are those such as 3-foot-long tubeworms, shrimps, crab, and anemone. The biggest discovery of these vents was that these organisms get their energy from the planet and not from a star.
What do black smokers contain?
The so called “black smokers” are hydrothermal vent chimneys formed by accumulations of iron sulfide, while “white smokers” are chimneys formed by accumulations of barium, calcium, and silicon.
Can anything survive in around a hydrothermal vent?
Most bacteria and archaea cannot survive in the superheated hydrothermal fluids of the chimneys or “black smokers.” But hydrothermal microorganisms are able to thrive just outside the hottest waters, in the temperature gradients that form between the hot venting fluid and cold seawater.
Where would you most likely go to find black smokers quizlet?
Hydrothermal vents such as black smokers are found at spreading centers. A seamount is a volcanic projection that does not rise above the surface. What are submarine canyons and how are they formed? Submarine canyons cut into the continental shelf and slope, often terminating the deep seafloor.
What role do hot spots and mantle plumes play in the breakup of a supercontinent?
Hot spots and mantle plumes melt the overlying continental lithosphere into liquid, creating a liquid-filled rift within the landmass. When hot mantle plumes reach the lithosphere, they weaken the lithosphere and create faults in the crust. Ultimately, the supercontinent breaks apart at these faults.
What happened when the spreading center that generated the Farallon plate collided with the North American plate?
What happened when the spreading center that generated the Farallon plate collided with the North American plate? The spreading center ultimately subducted beneath the coast of California. This event destroyed this spreading center and replaced it with a transform fault system.
Is it hot at the bottom of the ocean?
No matter how warm the surface of the ocean gets, the ocean’s huge volume and deep basins keep temperatures at the bottom of the ocean at only slightly above freezing. At the abyssal zone, the part of the sea closest to the vents, it’s way too cold to even dip a pinky into the water.
Is the Pompeii worm an animal?
