Limestone is an organic, sedimentary rock. This means it was formed from the remains of tiny shells and micro-skeletons deposited on the sea bed. Over the years this sediment was compressed to form solid rock. Limestone is formed in layers – called bedding planes. These bedding planes contain vertical cracks called joints.

Limestone is what's known as a "sedimentary" rock, meaning that it's formed from the accumulation of other organic and stone materials that have been fused together over time. In limestone's case, this sediment includes marine fossils, such as shells and coral. That's because millions of years ago, the areas where limestone forms ...

Limestone is used as a filler in a variety of products, including paper, plastic, and paint. The purest limestone is even used in foods and medicines such as breakfast cereals and calcium pills. Limestone is also the raw material for making lime (CaO) that is used to treat soils, purify water, and smelt copper. Lime has many additional uses in ...

Limestone has a hardness of around 3 to 4 on the Mohs scale, which means it is relatively soft. One way to test the hardness of limestone is to perform a scratch test. Using a mineral of known hardness, such as a fingernail (2.5), a copper penny (3.5), or a steel nail (5.5), try to scratch the surface of the limestone.

Limestone, Chalk. What is Limestone. Limestone is a sedimentary rock primarily composed of calcium carbonate (CaCO 3). Chemically, limestone undergoes lithification, where loose sediment transforms into a solid rock through compaction and cementation. The predominant mineral calcite forms during this process.
