MORE ABOUT KARST TOPOGRAPHY

What is karst topography?

Karst topography is a kind of landscape with a lot of sinkholes, caves, and underground streams. It is especially common in areas with frequent rain and ground made of easily dissolved rock, such as limestone.

Karst topography occurs when an area whose ground is loaded with soluble rocks gets a large amount of rain. Rainwater typically is at least somewhat acidic, and soluble rocks, such as limestone, will crack or dissolve when repeatedly exposed to acidic rain. Given enough time—maybe millions of years—ground water seeping into the dirt and rock will create vast networks of caves, tunnels, and streams underground. Above ground, the surface can look different depending on what part of the world the karst topography occurs in. However, one common effect is the creation of sinkholes, caused by the surface rock being weakened so much by water that it finally collapses.

Examples of karst topography can be found on every continent except Antarctica. Around 15 percent of the entire Earth’s landmass is some form of karst topography.

Why is karst topography important?

Topography refers to the features of a natural area (or a description or map of those features). Karst comes from a German word for the rocky region that covers parts of Italy and Slovenia. This area is now known simply as “the Karst.”

Karst topography can be found all over the world. Areas with karst topography are known as being great sources of clean drinking water because of how easily water flows through such areas without being contaminated. For these and other reasons, many regions of karst topography are the focus of nature preservation.
