UNIT 8 Karst topography Alvars or limestone pavements areas composed of slabs, divided by deep fissures, generally with sharp edges. Biology and Geology 3. Secondary Education

UNIT 8 Karst topography Sinkholes or dolines are funnel-shaped depressions which form in areas on the surface of the massif where water accumulates. Biology and Geology 3. Secondary Education

UNIT 8 Karst topography Poljes are large depressions resulting from the union of a number of sinkholes. Biology and Geology 3. Secondary Education

UNIT 8 Karst topography Collapsed sinkholes are enormous cavities with very vertical walls, which are formed when the inside of the massif is so hollowed-out that the surface (the roof of the cavities) collapses. Biology and Geology 3. Secondary Education

UNIT 8 Karst topography Canyons or gorges are deep ravines with vertical walls. Biology and Geology 3. Secondary Education

UNIT 8 Karst topography Cave The systems of cavities of a karst massif are composed of galleries, which are horizontal tunnels, potholes, which are vertical shafts, or caves, which are large cavities that are formed when the systems of potholes and galleries widen and join together.
