Karren is a geological term that refers to a type of landform created by the erosion of limestone or other soluble rocks. This process results in the formation of small, shallow depressions or channels on the surface, often filled with soil or vegetation. Karren features are commonly found in karst landscapes, which are characterized by unique topography due to the dissolution of soluble rocks. These landforms can vary in size and shape, depending on factors such as the type of rock and the environmental conditions. Karren is significant in the study of geology and geomorphology, as it helps scientists understand erosion processes and the development of karst systems, which include features like caves and sinkholes.
