The correct answer is: Limestone.
Limestone is a sedimentary rock composed mainly of calcium carbonate (CaCO3). It is the most common sedimentary rock type and the most widely used rock in construction. Limestone is formed when calcium carbonate-rich water, such as from springs or streams, precipitates out of solution and forms solid deposits. These deposits can be either clastic (made up of fragments of other rocks) or chemical (formed by the precipitation of minerals from solution).
Limestone is a very versatile rock and can be used for a variety of purposes, including:
- Construction: Limestone is a popular building material because it is strong, durable, and easy to work with. It is used to make bricks, concrete, and other building materials.
- Agriculture: Limestone is used as a fertilizer to improve soil quality and reduce acidity.
- Industrial: Limestone is used in the production of cement, glass, and other industrial products.
- Energy: Limestone is used in the production of lime, which is used in steelmaking and other industrial processes.
