what landform is not common in an area of karst topography?
plateau
karst topography is found throughout the driftless area. this is characterized by caves and cave systems, disappearing streams, blind valleys, underground streams, sinkholes, springs, and cold streams. disappearing streams occur where surface waters sinks down into the earth through fractured bedrock or a sinkhole, either joining an aquifer, or becoming an underground stream. blind valleys are formed by disappearing streams and lack an outlet to any other stream. sinkholes are the result of the collapse of the roof of a cave, and surface water can flow directly into them. disappearing streams can re-emerge as large cold springs. cold streams with cold springs as their sources are noted as superb trout habitat. due to the rapid movement of underground water through regions with karst topography, groundwater contamination is a major concern in the driftless area.

danxia landform









































the danxia landform () refers to various landscapes found in southeast, southwest and northwest china that "consist of a red bed characterized by steep cliffs". it is a unique type of petrographic geomorphology found in china. danxia landform is formed from red-coloured sandstones and conglomerates of largely cretaceous age. the landforms look very much like karst topography that forms in areas underlain by limestones, but since the rocks that form danxia are sandstones and conglomerates, they have been called "pseudo-karst" landforms. they were formed by endogenous forces (including uplift) and exogenous forces (including weathering and erosion).
