9. Karst Landscapes Flashcards
Karst landscape
Exposed areas of land made up of soluble rocks such as limestone
Porous rock
Contains empty spaces in which fluids, such as water, can be stored
Pervious rock
Has joints and bedding planes that allow water to pass through it
Soluble rock
Can be dissolved by carbonic acid through the process of carbonation
Aquifer
A body of rock that is capable of holding groundwater
Groundwater
Precipitation that has infiltrated the soil beyond the surface and collected in empty spaces underground
Water table
The upper level of an underground surface in which the soil is saturated with water
Joints
Vertical cracks in limestone
Bedding planes
Horizontal cracks in limestone that separate layers of rock strata
Grikes
Joints in rocks become wider, forming a series of gaps
Clints
The rest of limestone, not gaps, is divided into sections of flat-topped segments
Karrens
Small hollows that develop on clints
Flutings
Channels in the edges of clints, dissolved by rainwater
Enclosed depression
Enclosed hollows at the surface of limestone, can range up to hundreds of metres in depth and several kilometres in diameters
Doline/ sinkhole
Type of enclosed depression, small to medium in size
