Underground Limestone Features Stalagmite Stalactite Cavern Chemical Weathering By Jonathan Kirk Malham Cove All images taken from “google images”
Stalagmite Stalagmites are formed when water drops down and evaporates so depositing calcium carbonate on the ground and this builds up making stalagmites.
Stalactite Stalactites are formed when rain water falls from the roof of the cavern evaporating the water and depositing calcium carbonate (calcite).
Cavern Caverns are created when water runes underground and a chemical reaction causes limestone to be eroded, this continues to create a cavern.
Chemical Weathering Chemical weathering is the process at which limestone is weathered to create caverns and caves. CaCO3 + H2O + CO2 (Limestone calcium carbonate) (water) (Carbon dioxide from the atmosphere) Ca(HCO3)2 Calcium bicarbonate
Malham Cove Malham Cove has 3 types of rock: Silurian Limestone, Conbrifirous limestone, Bowland Shales. There is impervious rock where the surface rivers are and then porous rock where the swallow holes are this allows for the erosion of the limestone so caves and caverns can be created. This is essential for the creation of stalagmites and stalactites. Case study
