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 dolines and their formation and kinds, describe their role in karst hydrology and hazards, identify notable examples, and support geography, caving and conservation questions.

A closed depression in karst terrain formed by the dissolution of soluble rock such as limestone or by collapse into underground cavities, ranging from small bowl-shaped hollows to large compound uvalas, and including water-filled cenotes of the Yucatan, deep collapse dolines such as foibas, estavelles that alternately absorb and release water, and sumideros where streams sink underground; dolines are characteristic karst landforms, important for groundwater and often of ecological, archaeological and cultural significance.

What it is for: Karst depressions from dissolution or collapse.

It can be explain formation and kinds; describe hydrology and hazards; identify examples; support conservation questions.

Distinguishing features

Karst origin

Closed drainage

Dissolution or collapse

Groundwater link

What it looks like

Bowl-shaped or steep-sided hollows in limestone landscapes.

How it is recognised

Closed karst depression

Solution and collapse dolines, uvalas, cenotes, foibas

A crater is volcanic or impact; a kettle hole is glacial; a sink in a kitchen is unrelated
