Hydrothermal vents are the result of seawater percolating down through fissures in the ocean crust in the vicinity of spreading centers or subduction zones (places on Earth where two tectonic plates move away or towards one another). The cold seawater is heated by hot magma and reemerges to form the vents.Hydrothermal vents are the result of seawater percolating down through fissures in the ocean crust in the vicinity of spreading centers or subduction zones (places on Earth where two tectonic plates move away or towards one another).

How do deep-sea vent organisms survive in such extreme conditions?
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.
What are hydrothermal vents and where do they form?
Hydrothermal vents are naturally forming structures found in the ocean. They usually occur on divergent plate boundaries, where tectonic plates are moving apart. The vents expel a fluid that was heated to extreme temperatures when seeping through the Earth's crust from the ocean.
How did life on Earth start deep-sea vents?
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.
How are hydrothermal vents formed quizlet?
Hydrothermal vents are formed along divergent plate tectonic boundaries in the deep ocean. Cold sea water seeps into the cracks and fissures along these boundaries. They are heated by the hot underlying magma under the ocean floor. The hot water is forced back up to the ocean floor, carrying dissolved minerals.
What is the deep sea vent theory?
The theory goes: At the time of life's origin, the early ocean was acidic and filled with positively charged protons, while the deep-sea vents spewed out bitter alkaline fluid, which is rich in negatively charged hydroxide ions, Lane told LiveScience.
What are bacteria living in deep sea vents called?
Bacterial Diversity. The most abundant bacteria in hydrothermal vents are chemolithotrophs. These bacteria use reduced chemical species, most often sulfur, as sources of energy to reduce carbon dioxide to organic carbon.
Who created the deep-sea vent theory?
A set of famous experiments by chemist Stanley Miller in the 1950s showed that amino acids – the building blocks of proteins – could be synthesized in this way. The final major theory for the origin of life hinges on the last major ecosystem discovered on our planet: deep-sea hydrothermal vents.
What is the deep-sea vent theory?
The theory goes: At the time of life's origin, the early ocean was acidic and filled with positively charged protons, while the deep-sea vents spewed out bitter alkaline fluid, which is rich in negatively charged hydroxide ions, Lane told LiveScience.
Who discovered deep-sea vent theory?
It was February 1977, and Robert Ballard, a marine geologist at Woods Hole Oceanographic Institution (WHOI), sat aboard the research vessel Knorr 400 miles off the South American coast, staring at photos before him.
