In the Malham Cove area of the Yorkshire Dales, the landscape has been shaped by the erosion of limestone outcrops via chemical weathering, naturally acidic rain water and erosion through the movement of water and ice. Scars are bands of rock exposed by glaciers as they move through a valley. Underneath, scree is formed by broken rock which has fallen into the valley. Glaciation is also responsible for the exposure of flat limestone pavements. These have been further eroded by rainwater to form clints and grykes. Thanks to Ordnance Survey.
Students should produce annotated diagrams explaining the formation of physical features of limestone landscape. Compare with glacial features in other areas. Study of limestone can be linked to Chemistry topics related to its composition and reactivity.
