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.
Foundations · builds on
Planetary mantledepends onConvectionEstablished
planetary mantle depends on convection.
Mechanism: Slow convection in the mantle carries heat from the core and drives the plates at the surface.

Planetary mantlecausesPlate tectonicsEstablished
planetary mantle causes plate tectonics.
Mechanism: Mantle convection is the engine of plate tectonics — it drags the rigid plates across Earth's surface.

System context
Planetary mantleis part ofEarthEstablished
planetary mantle is part of Earth.
Mechanism: The mantle is Earth's thick middle layer of hot, slowly flowing rock; its convection drives the plates of the crust above.

Structural role & consequence
Interpreted from the current atlas graph — what the connections mean, not just how many there are.
Removing this node severs the only sampled structural route between Convection and Geothermal gradient — a non-redundant bridge here.
structural · Structural removal simulation — not a historical or causal counterfactual.
50% of its relationships cross field boundaries, reaching 5 other disciplines — unusual in a discipline where most concepts stay within their field.
structural · Structural graph analysis — not a claim of importance, causation or history.
Directly enables 1 concept; following enables/causes relations, 1 concept is downstream across 2 disciplines.
structural · Follows only enables/causes dependency edges — not general relatedness.
Currently dark in the atlas: no key date stored · 4 of 4 of its relations lack claim-level evidence.
atlas representation · Describes the current Thinking OS representation, not the state of the world.

Strengths & constraints
Strengths
- Cross-disciplinary connector — 50% 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
- Non-redundant bridge — removing it severs a sampled route between neighbouring clusters. structural
- No dated history stored — the atlas records no key date for this concept. atlas representation
Conditions
- Its dependency reading rests on 1 foundation relation. structural
- Read structurally — most of its relationships carry no external evidence yet, so claims here are graph-derived. structural

Seen through each discipline
How this concept sits in each of its fields — derived from its real connections in the graph, not asserted.
Through this lens it connects to Earth and Plate tectonics.

Stocks and flows
A stock is an amount that accumulates; flows are the rates that add to or drain it. The stock changes only when inflow and outflow differ.
Think of a bathtub: the water level (stock) rises or falls depending on the tap (inflow) and the drain (outflow).
Levels & hierarchy
Systems nest inside systems — parts form wholes that are themselves parts of larger wholes, each level with its own rules and language.
Pick the right level for the question: you rarely explain traffic with quantum physics. Zoom in for mechanism, out for behaviour.
- Connects 4 other ideas across 2 disciplines.
