Here's why:
* Karst topography is formed by the dissolution of soluble rocks, primarily limestone and dolomite, by acidic water. This process creates characteristic features like:
* Sinkholes: Depressions in the ground caused by the collapse of the roof of an underground cavern.
* Caves: Underground cavities formed by the dissolution of rock.
* Canyons: Deep, narrow valleys carved by erosion.
* Springs: Places where groundwater emerges at the surface.
* Volcanoes are formed by the eruption of magma and lava, a completely different geological process. They are not associated with the dissolution of soluble rocks and would not be found in karst landscapes.
