Is it true that an ocean-covered world obtains essential nutrients to support life via specific geological and atmospheric mechanisms?

Yes. Geological and atmospheric processes, such as hydrothermal venting, plate tectonics, and chemical cycling, play critical roles in supplying essential nutrients and maintaining habitability on ocean-covered or water-rich worlds.

Verdict: SUPPORTED · 4 sources for, 0 against · Last checked 4 Aug 2026

The analysis

The provided papers collectively support the claim that planetary-scale geological mechanisms (such as mid-ocean ridge hydrothermal activity, plate tectonics, and mantle-surface volatile cycling) and atmospheric or chemical interactions supply the necessary nutrients and chemical gradients to sustain life on ocean-covered or water-rich worlds. None of the papers refute this relationship.
