Some hydrothermal vents form roughly cylindrical chimney structures. These form from minerals that are dissolved in the vent fluid. When the superheated water contacts the near-freezing sea water, the minerals precipitate out to form particles which add to the height of the stacks.
Hydrothermal circulation in the oceans is the passage of the water through mid-oceanic ridge systems.. The term includes both the circulation of the well-known, high-temperature vent waters near the ridge crests, and the much-lower-temperature, diffuse flow of water through sediments and buried basalts further from the ridge crests.

The hydrothermal vents wouldn't normally be thought of as able to sustain a reliable habitat due to the turbulent nature of the vent fluid. However, researchers have found that the vents are stable for most of the year except for a 40 °C temperature spikes in the month of April.
The evidence suggests that deep-sea hydrothermal vent viral evolutionary strategies promote prolonged host integration, favoring a form of mutualism rather than classic parasitism. [32] As hydrothermal vents outlets [clarification needed] for sub-seafloor material, there is also likely a connection between vent viruses and those in the crust. [39]
New seafloor forms in places where magma is forced upward toward the surface at a mid-ocean ridge and cools to form volcanic rock. The hydrothermal vents spew into the cold sea the super-heated ...
Lost City and other hydrothermal vent systems support vastly different lifeforms due to Lost City's unique chemistry. A variety of microorganisms live in, on, and around the vents. Methanosarcinales-like archaea form thick biofilms inside the vents where they subsist on hydrogen and methane; bacteria related to the Bacillota also live inside ...
Hydrothermal vein ore deposits consist of discrete veins or groups of closely spaced veins. Veins are believed to be precipitated by hydrothermal solutions travelling along discontinuities in a rockmass. [10] They are commonly epithermal in origin, that is to say they form at relatively high crustal levels and moderate to low temperatures.
Hydrothermal vents at the bottom of the ocean spit out liquids that can reach temperatures of over 750 degrees Fahrenheit, according to National Geographic. Some organisms—extremophiles—have ...
