Limestone Scenery Limestone is made up of CalciumCarbonate. It is a sedimentary/igneous rock. It was laid down in layers on dry land/the sea bed. The junctions between the layers are called cracks/bedding planes. Weaknesses in thelayers of limestone are calledjoints/joins. Limestone is a(n) permeable/impermeablerock. This means water cannot/can pass through it. Rainwater is slightly acid/alkalineso it slowly dissolves the limestone where it is weak/strongalong the joints. PS. This is task 3 on your worksheet
