Sedimentary rocks are emplaced and then folded. Erosion takes place, followed by more deposition. Be able to order the steps of the formation of a nonconformity. Sedimentary rock layers are deposited and then intruded by a pluton. Erosion exposes the pluton at the surface. Sediments are once again deposited, covering the erosional surface.

Limestone is a sedimentary rock composed of calcium carbonate typically derived from the remains of fossil animal shells.
