Dependencies
What this concept builds on and what it makes possible — derived from the atlas’s dependency, causal and structural relations, not from every related edge.
System context
Planetary differentiationis part ofPlanetEstablished
Planets settle into layers.
Mechanism: Heat lets a young planet's dense metal sink to a core, leaving mantle and crust.
Structural role & consequence
Interpreted from the current atlas graph — what the connections mean, not just how many there are.
100% of its relationships cross field boundaries, reaching 1 other discipline — unusual in a discipline where most concepts stay within their field.
structural · Structural graph analysis — not a claim of importance, causation or history.
Currently dark in the atlas: no key date stored · 1 of 1 of its relations lack claim-level evidence.
atlas representation · Describes the current Thinking OS representation, not the state of the world.
Structural neighbourhood: 1 → 8 → 35 concepts reachable within 3 hops.
structural · Structural reach — being reachable is not the same as being understood.

Strengths & constraints
Strengths
- Cross-disciplinary connector — 100% of its relationships cross field boundaries. structural
Constraints
- Evidence coverage currently thin in the atlas — few of its relationships carry claim-level evidence. atlas representation
- No dated history stored — the atlas records no key date for this concept. atlas representation
Conditions
- Read structurally — most of its relationships carry no external evidence yet, so claims here are graph-derived. structural
