\n Introduction
\n A living world may need a moving crust.
\n Plate tectonics is the slow movement of a planet's outer shell. On Earth, it helps recycle carbon between rocks, air, oceans, and volcanoes, which can stabilize climate over long times. It also builds continents and reshapes habitats. The process depends on heat, water, rock strength, planet size, and interior dynamics. Habitability is not only about where a planet sits, but how it works inside.

Why it matters
\n
It explains why moving plates matter for climate and life.
\n
\n
\n
What this does not mean
\n
It does not prove plate tectonics is required for every possible biosphere.
\n

\n
How it pressures the map
\n
It adds long-term climate regulation to the habitability cluster.

Plate tectonics and planetary habitability asks how a measured feature of nature should be read once competing explanations are allowed into the room. The ordinary-language version is this: Plate tectonics recycles carbon and stabilizes climate; requires a delicate planetary regime. Read it as disciplined contact with nature: the measurement matters, and so do the limits of what the measurement can say. In the scoring table, its main conversation partners are Deism (H-DEISM), God (H-GOD), God–OT (Classical Theism) (H-GOD-OT); that is a map of relevance, not a declaration that the item settles those hypotheses by itself.
\n
The basic idea is simple: Plate tectonics recycles carbon and stabilizes climate; requires a delicate planetary regime. That is the thing to notice before the technical labels and numbers arrive.
\n
Science rows are not shortcuts from a lab result to a worldview. They ask a narrower and more interesting question: what kind of reality makes this pattern, mechanism, or constraint feel expected rather than strange? The answer may help the map, but it should not pretend to be more precise than the evidence allows.
\n
If fine-tuning is new language, think of a lock with many dials: the discussion is about whether the life-permitting settings look accidental, necessary, selected, or intended.
\n
In the scoring table, this item mainly talks to Deism (H-DEISM), God (H-GOD), God–OT (Classical Theism) (H-GOD-OT), and nearby alternatives. That does not mean the item proves those views true or false; it means the clue leans, however slightly or strongly, in those directions within the model.

Read this as science or mind evidence with scope-limited worldview relevance. Its category path is Science / Fine-Tuning / Habitability Conditions, which helps set expectations for what kind of question this row can answer.
\n
\n
This matters because explanations have habits. Some worlds make this clue feel ordinary; others have to work harder to account for it. The Signal tracks that difference without pretending that one row can settle the whole journey.

\n
The current numerical weight is intentionally bounded: H-DEISM: +0.05 log10BF; H-GOD: +0.10 log10BF; H-GOD-OT: 0.00 log10BF; H-IDEALISM: 0.00 log10BF. In ordinary language, this row changes the angle of the map; it does not carry the whole argument on its back.
