Karst landscapes are shaped by the erosion of soluble carbonate rocks such as limestone, creating features such as sinkholes, caves and underground rivers. In a piece for The UNESCO Courier ...

Florida, rich in limestone, is especially susceptible to sinkholes. "Sinkholes are most common in what geologists call, 'karst terrain'," the US Geological Survey (USGS) explains. "These are ...

When water collects in sinkholes, sometimes ponds are formed. Due to the local Karst landscape and humid climate, a sinkhole more than 950 feet deep in Xuan'en County, China, has become home for ...

The ceilings therefore collapsed to the bottom, opening up the enormous sinkholes. China's tiankeng are unique, according to Zhu Xuewen, a researcher at the Institute of Karst Geology at the ...

Sinkholes are part of a karst landscape that forms when soft, soluble rocks, such as limestone or dolomite, dissolve with water. The soluble limestone and dolomitic rocks, combined with melting snow ...

forming underground caves and cracks called karst formations (Figure 2a). Further erosion of bedrock along the cave ceilings caused collapses leaving visible sinkholes. Figure 2b shows areas of on ...

These sinkhole-susceptible areas are areas called "karst terrain," which covers about 20 percent of the U.S. We asked USGS geologist David Weary for his thoughts. He told Business Insider in an ...

A karst is a type of landscape formed when limestone in the ground is dissolved by water and creates features such as sinkholes and caves. In her previous report nominating the Munro Karst caves ...
