Thedevelopment of all karst landforms requires the presence of rock which is capable of being dissolvedby surface water or ground water. The term karst describes a distinctive topography that indicates dissolution (also called chemicalsolution) of underlying soluble rocks by surface water or ground water.y studying the animations and the paper model, students will better understand theevolution of Karst topography.Included in the paper and diskette versions of this report are templates for making a paper model,instructions for its assembly, and a discussion of development of Karst topography.
