Karst (/ kɑːrst /) is a topography formed from the dissolution of soluble carbonate rocks such as limestone and dolomite.

2024年7月3日 · Karst is an area of land made up of limestone. Limestone, also known as chalk or calcium carbonate, is a soft rock that dissolves in water. As rainwater seeps into the rock, it slowly erodes. Karst landscapes can be worn away from the …

2022年4月27日 · Karst is a type of landscape where the dissolving of the bedrock has created sinkholes, sinking streams, caves, springs, and other characteristic features. Karst is associated with soluble rock types such as limestone, marble, and gypsum.

2024年12月27日 · karst, terrain usually characterized by barren, rocky ground, caves, sinkholes, underground rivers, and the absence of surface streams and lakes. It results from the excavating effects of underground water on massive soluble limestone.

“ We may define karst as comprising terrain with distinctive hydrology and landforms that arise from a combination of high rock solubility and well developed secondary (fracture) porosity. Such areas are characterized by sinking streams, caves, enclosed depressions, fluted rock outcrops, and large springs.

2023年11月24日 · The characteristics of karst landscapes vary depending on factors such as: soluble bedrock type, climatic environment (more specifically precipitation and temperature), geographic position (both globally and locally), overlying soil materials, and vegetation cover (Figure 12.2.1).

Simply speaking, karst is a type of landscape. It is formed by water dissolving certain types of rocks, creating features such as caves and sinkholes. But karst is far from simple, as you’ll see in these pages. Where is karst? Why is karst important?

2023年11月24日 · Karstification is a process dominated by chemical dissolution of soluble bedrock (Figure 12.1.1). It starts as carbon dioxide from the atmosphere dissolves in rainwater falling to the surface of the Earth.

2021年3月24日 · Karst topography refers to a type of subterranean limestone caverns landscape, as well the mysterious-looking formations like caves, surface sinkholes, and rocky, overhanging cliffs, as a result of a specific natural occurrence.

Karst is the land of caves, sinkholes, and sinking streams and is formed when soluble rocks are dissolved by water. Karst occurs worldwide and in the United States, approximately 20 percent of the land surface is karst.
