Web15 apr. 2014 · According to the findings, which also can be thought of as the "water world" theory, life may have begun inside warm, gentle springs on the sea floor, at a time long ago when Earth's oceans churned across the entire planet. This idea of hydrothermal vents as possible places for life's origins was first proposed in 1980 by other researchers, who ... Web11 jun. 2024 · Hydrothermal vents form in volcanic areas where subseafloor chambers of rising magma create undersea mountain ranges known as mid-ocean ridges. Cold seawater seeps into cracks in the seafloor and can be heated up to a raging 750° F (400° C) by interacting with magma-heated subsurface rocks.
