Answer:
The evolution of karst landscape is by the interaction of water with limestone rocks.
Explanation:
- The karst topography is formed by the dissolved soluble rocks like the limestone and dolomite and featured by the sinkholes and caves.
- The development of the karst occurs when the acidic water starts to break down the surface bedrocks and cracks open in the bedding plane, as time passes these features gets wider and leads to the development of a drainage system. Carbonic acid is one of the main mechanisms for the formation of features.
- The karst landscape has a variety of small features and these include the sinkholes, limestone payments, cave pillars, stalactites, and stalagmites. Hazards associated with the karst landscape are erosion by rivers, sinkholes, and hollow holes and Karst wells, etc.
- The relations between the groundwater and surface water are water quality and quantity. The subsurface layer creates a filter and cleans water from other impurities.
