layer
a relatively thin sheetlike expanse or region lying over or under another
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain layers as positioned sheetlike regions across natural and made things, describe how layers are named, ordered and studied in fields such as anatomy, geology, meteorology and engineering, support questions about layered structures, and separate this sense from other senses of the word.
A relatively thin sheetlike expanse or region lying over or under another, such as the layers of the skin from the horny outer layer downward, the layers of the atmosphere and ocean, strata of rock and soil, coats of paint and coatings, layers of a cake or of clothing, and layers in constructed and abstract structures; in this sense a layer is defined by its position within a stack and is distinct from the person or device that lays something down.
What it is for: Thin regions stacked over or under others.
It can be explain the concept; describe layers across fields; support layered structure questions; separate other senses.
Distinguishing features
Sheetlike
Stacked position
Boundaries
Cross-field use
What it looks like
Sheetlike bands in cross-section.
How it is recognised
Thin expanse over or under another
Skin, atmosphere, rock, coatings, clothing
A level is a position in a hierarchy; a coat is one applied layer; a hen that lays eggs is a different sense
