what is a 6 word (or more) definition of karst topography?

Answer 1

Karst topography is a landscape created by groundwater dissolving sedimentary rock such as limestone.

Answer 2

Karst is a distinctive landscape topography largely formed by the dissolving of carbonate bedrocks such as limestone, dolomite, or marble by water. This geological process results in unusual surface and subsurface features ranging from sinkholes, vertical shafts, disappearing streams, and springs, to complex underground drainage systems and caves. The most famous of these features are caves. A speleothem is a technical term for any of the formations found in caves such as stalagmites, stalactites, columns, cave pearls, and so forth. Although caves are commonly associated with limestone and karst, not all caves are formed this way. Some famous caves are lava tubes. A lava tube is an underground conduit for magma that later drains and becomes an underground tunnel. Caves can be formed by other geological processes which you can find in some of the links listed below.

Answer 3

Karst topography is a three-dimensional landscape shaped by the dissolution of a soluble layer or layers of bedrock, usually carbonate rock such as limestone or dolomite. These landscapes display distinctive surface features and underground drainages, and in some examples there may be little or no surface drainage. Some areas of karst topography, such as southern Missouri and northern Arkansas in the USA, are underlain by thousands of caves.
