  • Does limestone have value Answers

    Limestone itself is a building material. The pyramids in Egypt are made of blocks of limestone. Limestone is composed mostly of a chemical called Calcium carbonate. When this is heated, it looses a molecule of CO2 and becomes Calcium oxide. Calcium oxide is known as lime. Lime is one of the main ingredients in cement.

    Limestone is partially soluble, especially in acid, and therefore forms many erosional landforms. These include limestone pavements, pot holes, cenotes, caves and gorges. Such erosion landscapes are known as karsts. Limestone is less resistant than most igneous rocks, but more resistant than most other sedimentary rocks.
