Geoterms

• Solution occurs when water that contains carbonic acid dissolves permeable limestone
• A grike is a vertical crack that develops along a joint in limestone. It is formed by water dissolving the rock.
• A clint is a section of a limestone pavement that is separated from adjacent sections by grikes
• A karren is a small hollow that forms on the surface of a limestone clint. They are formed by rainwater and acids ponding on the surface
• Fluting occurs if the weathered hollow runs off the edge of the clints
• Abrasion is a process of erosion where the rocks and stones carried by the river erode the bed and bank over which it passes
