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 coal as a rock and fuel and its ranks and types, describe mining, use and trade, present environmental, health and policy issues with attribution, and support geology and history questions.

A combustible black or brownish sedimentary rock formed from compressed plant remains over millions of years, ranked from lignite through sub-bituminous and bituminous coal to anthracite by carbon content, and classified petrographically into components such as vitrain, clarain, durain and fusain and into thermal coal for power and metallurgical coal for steelmaking; coal powered industrialisation, remains a major but declining energy source, and is the largest single source of energy-related carbon dioxide emissions.

What it is for: Combustible sedimentary rock and fuel.

It can be explain ranks and types; describe mining and use; present environmental and policy issues; support geology questions.
