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.
Enables · leads to
Foundation (structure)requiresSoilEstablished
A foundation depends on the soil.
Mechanism: A foundation must transfer load into the soil beneath it, so its design depends on the soil's bearing capacity.
System context
Permafrostis aSoilEstablished
permafrost is a kind of soil.
Mechanism: Permafrost is soil (or rock) that stays frozen for at least two years; thawing it releases trapped carbon and destabilises the ground.

Sedimentis part ofSoilEstablished
sediment is part of soil.
Mechanism: Sediment is a major ingredient of soil: weathered mineral particles mix with decayed organic matter, water and air to form the layer plants root in.

Soil horizonis part ofSoilEstablished
Horizons are the layers of a soil.
Mechanism: Weathering and biology sort a soil into stacked layers from surface litter down to bedrock.
Soil organic matteris part ofSoilEstablished
Soil organic matter is a part of soil.
Soil textureis part ofSoilEstablished
Soil texture is a part of soil.
Structural role & consequence
Interpreted from the current atlas graph — what the connections mean, not just how many there are.
Removing this node lengthens the structural route between Farm machinery and Foundation (structure) from 2 to 8 steps (they stay connected — alternative routes exist).
structural · Structural removal simulation — not a historical or causal counterfactual.
60% of its relationships cross field boundaries, reaching 8 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.
Currently dark in the atlas: no key date stored · 10 of 10 of its relations lack claim-level evidence.
atlas representation · Describes the current Thinking OS representation, not the state of the world.
Structural neighbourhood: 10 → 25 → 50 concepts reachable within 3 hops.
structural · Structural reach — being reachable is not the same as being understood.

Strengths & constraints
Strengths
- Cross-disciplinary connector — 60% 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
Dependency radial
What this concept builds on (left) and what it makes possible (right) — derived from dependency and causal relations.
What builds on this
1 concept build on this directly, 1 in total, across 2 disciplines.
Structural downstream reach along dependency edges — not a claim of historical necessity.
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 Soil horizon, Sediment, Desertification and Permafrost.
