| Question | Answer |
| Bedding plane | The horizontal spaces between the layers or strata in limestone rock. |
| Calcium carbonate | A colourless or white crystalline compound, CaCO3, occurring naturally. Eg. chalk, limestone, marble. |
| Calcite | A white of colourless mineral consisting of calcium carbonate. |
| Carbonation | Type of chemical weathering in which limestone is broken down by the carbonic acid in rainwater. |
| Cavern | An underground cave whose opening is also underground. |
| Carbonic acid | A mixture of rainwater (H2O) and carbon dioxide (CO2). |
| Chemical weathering | When rocks are dissolved because of a chemical reaction e.g. carbonation. |
| Clint | Blocks of limestone left in between grikes. |
| Denudation | The wearing down of the Earth's surface by erosion or weathering. |
| Erosion | The breaking down and removal of material by water, wind or ice. |
| Fluctuating | Increasing and decreasing at an uneven rate. |
| Freeze-thaw action | Type of mechanical weathering where rock is broken down due to water in cracks repeatedly freezing and thawing. |
| Grike | Grooves or gaps between the limestone blocks. |
| Joint | The long vertical crack in limestone rock. |
| Karst | A limestone area with surface or underground features made by chemical weathering. |
| Limestone pavement | The surface of a karst landscape. |
| Mechanical weathering | The physical breaking up of rocks into smaller pieces by putting pressure on the rock Eg. freeze-thaw action. |
| Regolith | Rock fragments that have broken away from solid rock through weathering and erosion. |
| Stalagmite | Icicle-shaped structure which grows upwards from the floor of a cave , made from the deposits of calcite. |
| The Burren | The Burren is located in Co.Clare. It is a karst region. |
| Scree | Small pieces of rock created due to mechanical weathering. |
| Limestone pillar | Formed when a stalactite and a stalagmite join. |
| Weathering | The breakdown and decay of rocks by mechanical and chemical processes. |
| Swallow hole | Holes through which rivers in limestone areas disappear underground. |
| Stalactite | Icicle-shaped structure which grows downwards from the ceiling of a cave, made from deposits of calcite. |
| Limestone curtain | A curtain like feature hanging from the ceiling of the cave, when calcite is deposited as droplets run horizontally across a surface. |
