Where do karsts form?
Underground rivers, also known as subterranean rivers, flow at least partly beneath the surface of the Earth. Many underground rivers are part of a karst landscape, where eroded limestone often creates caves.

Why is it called karst?
The word 'karst' has its origins in pre-Indo-European languages, from kar, meaning 'rock'. In Slovenia the word 'kras' (or 'krs'), subsequently germanicized as 'Karst', derives from the name of a barren stony limestone area near Trieste, which is still considered the type area for limestone karst.

What is a polje?
A polje, in geological terminology, is a large, flat-floored depression within karst limestone, whose long axis develops in parallel with major structural trends and can become several miles (tens of kilometers) long. Superficial deposits tend to accumulate along the floor. Drainage may be either by surface watercourses (as an open polje) or by swallow holes (as a closed polje) or ponors. Usually, the ponors cannot transmit entire flood flows, so many poljes become wet-season lakes. The structure of some poljes is related to the geological structure, but others are purely the result of lateral dissolution and planation. The development of poljes is fostered by any blockage in the karst drainage.
