Limestone is a sedimentary rock that is found over large areas of the United States. Using this information, explain what the environment of deposition was like at the time of limestone formation and how the mineral in the limestone formed?
What will be an ideal response?
Answer: Limestone forms in shallow marine environments, so without any additional information, it can be inferred that large areas of the United States were once covered with a shallow sea. However, limestone is often formed through the secretion of CaCO3 by marine organisms such as clams and corals, so the primary method of mineral formation is minerals formed by biological processes. This inference would be supported by the presence of marine fossils.
