Meaning of Karst Topography or Limestone Region

Limestone region refers to a large stretch of land occupied by limestone which possesses a unique type of topography. Limestone is a sedimentary rock of organic materials made up of calcium carbonate. They are derived from accumulation of corals and shell in the sea. When magnesium is present it is termed DOLOMITE. Chalk is a very pure form of limestone, white and rather soft.

EVALUATION

  1. Explain the term karst topography.

 

Characteristics of Karst Topography

1. Solubility:

Limestone is in soluble but is made soluble by the action of rain water which dissolves carbon dioxide to form a weak acid which in turn acts upon it (limestone) to make it soluble.

2. Absence of Luxuriant Vegetation Cover:

There is complete absence of thick vegetation cover in limestone region.
