WebTo put in plainly, the hydrothermal vent is a hot spring created when seawater encounters hot magma. ... The very high pressure of the deep sea is the reason why the water does not boil is such extreme … Life has traditionally been seen as driven by energy from the sun, but deep-sea organisms have no access to sunlight, so biological communities around hydrothermal vents must depend on nutrients found in the dusty chemical deposits and hydrothermal fluids in which they live. Previously, Benthic oceanographers assumed that vent organisms were dependent on marine snow, as deep-sea organisms are. This would leave them dependent on plant life and thus the sun. …
WebSince their discovery, submarine hydrothermal vent systems have been pointed out as important places where chemical evolution on Earth could have occurred; and their role in the process has been highlighted. Similarly, some hypotheses have considered these systems in origin of life scenarios. WebHydrothermal vents are analogous to hot springs on land. They are usually found in water between 2,000 and 4,000 m deep; however, shallow water vents have been observed …
