Answer:
surface drainage systems
Explanation:
Karst is a kind of topography that is formed from the dissolution of soluble rocks (e.g. limestone, dolomite, and gypsum). It is composed by an underground drainage systems with sinkholes and caves, so a stream cannot be formed in this kind of topography.
The solubility of limestone in water and weak acid solutions leads to karst landscapes. Flowing rivers, can be found in areas away from karst topography. Sinkhole is not associated with areas of Karst topography.
Karst topography may contain sinkholes or funnel-shaped holes in the surface of the land, caverns, caves, and underground rivers. Karst topography varies greatly, from steep jagged cliffs to soft rolling hills; from microscopic in size to hundreds of square miles. Karst regions are found all over Earth.
