9 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 the layers of limestone are called joints/joins. Limestone is a(n) permeable/impermeable rock. This means water cannot/can pass through it. Rainwater is slightly acid/alkaline so it slowly dissolves the limestone where it is weak/strong along the joints. PS. This is task 3 on your worksheet
