- 1Bedding planeThe horizontal spaces between the layers or strata in limestone rock.
- 2Calcium carbonateA colourless or white crystalline compound, CaCO3, occurring naturally. Eg. chalk, limestone, marble.
- 3CalciteA white of colourless mineral consisting of calcium carbonate.
- 4CarbonationType of chemical weathering in which limestone is broken down by the carbonic acid in rainwater.
- 5CavernAn underground cave whose opening is also underground.
- 6Carbonic acidA mixture of rainwater (H2O) and carbon dioxide (CO2).
- 7Chemical weatheringWhen rocks are dissolved because of a chemical reaction e.g. carbonation.
- 8ClintBlocks of limestone left in between grikes.
- 9DenudationThe wearing down of the Earth's surface by erosion or weathering.
- 10ErosionThe breaking down and removal of material by water, wind or ice.
- 11FluctuatingIncreasing and decreasing at an uneven rate.
- 12Freeze-thaw actionType of mechanical weathering where rock is broken down due to water in cracks repeatedly freezing and thawing.
- 13GrikeGrooves or gaps between the limestone blocks.
- 14JointThe long vertical crack in limestone rock.
- 15KarstA limestone area with surface or underground features made by chemical weathering.
- 16Limestone pavementThe surface of a karst landscape.
- 17Mechanical weatheringThe physical breaking up of rocks into smaller pieces by putting pressure on the rock Eg. freeze-thaw action.
- 18RegolithRock fragments that have broken away from solid rock through weathering and erosion.
- 19StalagmiteIcicle-shaped structure which grows upwards from the floor of a cave , made from the deposits of calcite.
- 20The BurrenThe Burren is located in Co.Clare. It is a karst region.
- 21ScreeSmall pieces of rock created due to mechanical weathering.
- 22Limestone pillarFormed when a stalactite and a stalagmite join.
- 23WeatheringThe breakdown and decay of rocks by mechanical and chemical processes.
- 24Swallow holeHoles through which rivers in limestone areas disappear underground.
- 25StalactiteIcicle-shaped structure which grows downwards from the ceiling of a cave, made from deposits of calcite.
- 26Limestone curtainA curtain like feature hanging from the ceiling of the cave, when calcite is deposited as droplets run horizontally across a surface.
