Limestone is a sedimentary rock composed primarily of calcium carbonate (CaCO3). It is formed when the remains of marine organisms, such as coral and shellfish, are buried and compressed over time.
Limestone is a versatile rock that has a wide variety of uses, including construction, agriculture, and manufacturing.

Types of limestone include:

Chalk: A soft, white limestone that is composed of microscopic fragments of the shells of marine organisms. Chalk is used in a variety of applications, including making chalkboards, tennis balls, and toothpaste.

Coquina: A limestone that is composed of the fragments of shells, coral, and other marine organisms. Coquina is used in a variety of applications, including making building materials, walkways, and patios.

Travertine: A limestone that is formed by the precipitation of calcium carbonate from mineral springs. Travertine is used in a variety of applications, including making fountains, sculptures, and countertops.

Oolitic limestone: A limestone that is composed of small, round grains that are called ooids. Ooids are formed when calcium carbonate is deposited around a nucleus, such as a sand grain or a piece of organic matter. Oolitic limestone is used in a variety of applications, including making building materials and ornamental objects.

Fossiliferous limestone: A limestone that contains fossils. Fossiliferous limestone is used in a variety of applications, including making decorative objects and teaching tools.

Uses of limestone include:
Construction: Limestone is used to make a variety of building materials, including bricks, blocks, and tiles. It is also used to make concrete and mortar.

Agriculture: Limestone is used to improve soil quality by adding calcium and other nutrients. It is also used to reduce soil acidity.

Manufacturing: Limestone is used to make a variety of products, including paper, plastics, and fertilizers. It is also used in the production of glass and ceramics.

Other uses: Limestone is also used to make chalk, grout, and whitewash. It is also used as a decorative stone in landscaping and architecture.

Limestone is a valuable resource that has a wide variety of uses. It is a sustainable material that can be recycled and reused. Limestone is also a relatively inexpensive material, which makes it a cost-effective option for a variety of applications.
