Why do areas with limestone bedrock not exhibit karst topography?
Usually, they do, but it can not happen if: -water table too low -limestone altered to silica, dolomite -limestone is silty
Limestone and dolomite are two of the key rock forms found in karst topography.There are several books on this and the following web sites
Karst Topography is the device of underground caves and sinkholes in a (somewhat) flat limestone terrain. Carbonic acid (H2CO2) etches out limestone alongside fractures in the limestone, in the approach turning out to be this topography.
