GEOLOGY

Detailed explanation-1: -A landscape that is characterized by numerous caves, sinkholes, fissures, and underground streams. Karst topography usually forms in regions of plentiful rainfall where bedrock consists of carbonate-rich rock, such as limestone, gypsum, or dolomite, that is easily dissolved.

Detailed explanation-2: -A karst terrain is a land surface produced by water dissolving the bedrock and is characterized by sinkholes, cavern systems and disappearing streams and springs. The Alafia River watershed is a textbook example of karst topography.

Detailed explanation-3: -Sinkholes are most common in what geologists call, “karst terrain.” These are regions where the types of rock below the land surface can naturally be dissolved by groundwater circulating through them. Soluble rocks include salt beds and domes, gypsum, limestone and other carbonate rock.

Detailed explanation-4: -Sink Holes – It is one of the most common features in Karst Topography.

Detailed explanation-5: -Types of Karst Topography Some karst regions are sharp jagged hills, while others are soft rolling hills with depressions that used to be sinkholes. These sinkholes are characteristic of karst landscapes, and are places where the surface collapses in on itself, creating a funnel-shaped hole in the ground.
