Karst topography is a geologic terrain created from the dissolution of . The slightly acidic nature of water causes a reaction with and in turn, creates various land-forms due to differential erosion. On the surface, karst topography features can vary depending upon the amount of time that erosion has occurred, but under the surface, vast networks of caves can develop and within these caves, you will find various speleothems that include which protrude from the cave roof and which accumulate on the cave floor.

Karst topography is a geological terrain created from the dissolution of carbonates. The slightly acidic nature of the water causes a reaction and, in turn, creates various landforms due to differential erosion. On the surface, the characteristics of karst topography can vary depending on the amount of time erosion has occurred, but below the surface, vast cave networks can develop and within these caves, you will find several speleothems including those that protrude from the ceiling of the cave and accumulate on the floor of the cave.

Explanation:

It is an extremely beautiful relief that is said to have undergone a chemical process of dissolution called karstification.

On the other hand, this was due to chemical weathering of rocks.

A karst is produced by indirect dissolution of calcium carbonate from limestone rocks due to the action of slightly acidic waters. Water is acidified when it is enriched in carbon dioxide, for example when it passes through a soil, and reacts with carbonate, forming bicarbonate, which is soluble. There are other types of rocks, evaporites, such as gypsum, that dissolve without the need for acidic water. The surface and underground waters dissolve the rock and create galleries and caves that, by partial sinking, form sinkholes and, by total sinking, form canyons.
