Limestone and its uses

Using Limestone                                                                 There are many uses for Limestone a few of them are: Limestome is mostly made up of calcium carbonate (CaCO3), and this substance is a important raw material used to make glass, cement and concrete.
 * Making buildings
 * As th base for roads and railways

Limestone is heated when making glass and cement. The heat decomposes (breaks down) the calcium carbonate in it to form calcium oxide (CaO) and carbon dioxide (Co2). This process is called theramal decomposition.

Quarrying- Good or Bad
Advantages- Disadvantages-
 * Limestone is a important raw material
 * Quarries provide jobs
 * Some lime stone is expostred to other countries, which helps the UK economy
 * Jobs in quarries also help local ecomonies, because the workers spend their money in local shops and businesses
 * Quarries produce dust and noise
 * Digging a quarry destroys habitats for wildlife
 * Quarries spoil the scenery (although they are usually landscaped after quarrying has finished and can become wildlife reserves or recreation areas).
 * Lorries taking the limestone away, causes extra traffic, noise and pollution
