outcrop
Let an agent explain outcrops and their formation and significance, support field observation and description, describe stratotypes and geological heritage, and support geology learning and site questions.
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 outcrops and their formation and significance, support field observation and description, describe stratotypes and geological heritage, and support geology learning and site questions.
A visible exposure of bedrock or ancient superficial deposits at the surface of the Earth, occurring naturally on cliffs, mountainsides, riverbanks and coasts and artificially in quarries, cuttings and excavations, including named rock formations and groups of rocks, sandstone and other lithological outcrops, and stratotype outcrops that define geological units; outcrops are the primary sources of geological observation and are mapped, sampled and protected as geological heritage.
What it is for: Exposures of bedrock at the surface.
It can be explain formation and significance; support field description; describe stratotypes and heritage; support learning.
Distinguishing features
Exposed bedrock
Natural or artificial
Observation site
Heritage value
What it looks like
Exposed rock faces and formations.
How it is recognised
Bedrock exposed at the surface
Cliffs, riverbanks, quarries, cuttings, named formations
Soil and vegetation cover hide bedrock; a boulder is a detached rock; a landform is the shape
