limestone
Let an agent explain limestone by type and formation, support building and heritage uses, describe karst and groundwater, and address safety and environmental aspects of quarrying and use.
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 limestone by type and formation, support building and heritage uses, describe karst and groundwater, and address safety and environmental aspects of quarrying and use.
A sedimentary rock composed mainly of calcium carbonate, formed from marine organisms, shells and chemical precipitation, including varieties such as chalk, oolite, coral stone and named building stones like Portland and Istrian stone; limestone is used for construction, cement, lime and agriculture, forms karst landscapes and holds fossils and groundwater.
What it is for: Construction, industry, agriculture and landscape.
It can be identify limestone types; explain formation and karst; describe uses in building and industry; address weathering and conservation.
