Question

Give a geographical reason:

Karst landforms are seen concealed under the surface of the earth.

Answer 1

Karst landforms are seen concealed under the surface of the earth because -

1. The warmer humid climate has a greater amount of vegetation, which supplies CO₂ to sub-surface water.
2. CO₂ is necessary for the acidity of water which makes dissolving easier.
3. Water saturated with dissolved CO₂ should have easy movement.
4. The greater the permeability of the rock, the faster groundwater will flow.
5. The fractures and joints in the rocks allow the passage of water.
6. In the areas of water-soluble rocks, such as limestone and gypsum the acidic water dissolves the rock and various landforms develop underground.
7. Thus, landforms developed by underground water anywhere in the world are called karst landforms.
