Limestone is a sedimentary rock composed mainly of calcium carbonate (CaCO3). It is the most common sedimentary rock on Earth, and it is found in a variety of colors, including white, gray, brown, and black. Limestone is formed when the remains of marine organisms, such as coral, algae, and shellfish, are buried and compacted over time.
