What is limestone?
Limestone: Limestone is a sedimentary rock composed largely of the mineral calcite (calcium carbonate: CaCO 3 ). A type of limestone known as dolomite is composed of calci…um magnesium carbonate CaMg(CO 3 ) 2 . Millions of shelled creatures die in the seas and their bodies fall to the ocean floor. Calcium carbonate is the largest constituent of the shells of sea creatures. The soft parts are eaten or rot away and the shells remain. The shells are compressed into a hard mass that we call limestone. Due to the method of formation describe above, there can be impurities mixed in with the limestone - sand, organic material etc. These change the texture and color. Limestone can be dissolved and re-deposited by precipitation and groundwater flows. Acidic water passing through limestone beds can dissolve the calcium carbonate and precipitate it out as the temperature and acidity changes or the water evaporates. Stalactites and stalagmites are formed in this manner. Uses for limestone: .
Glass making .
Ingredient in toothpaste .
Bread and cereals as a source of calcium .
Making paper white .
Sugar purification .
Making brake pads .
Preparation of wools and dyes .
Climbing walls .
A suppression of methane explosions in underground coalmines .
Manufacturing of quicklime (calcium oxide) and slaked lime (calcium hydroxide). .
Manufacturing of steel .
Lower water pH .

Where do you get limestones from?
The hard shells of living things produce some kinds of limestone. How dopes limestone form? Limestone forms in the ocean, many living things, including coral, clams, oysters,… and snails, have shells or skeletons made of calcite. There shells pile up as sediments on the ocean floor. It turns into calcite cement after millions of years which pieces together forming limestone. Limestone is also known as chalk. .
Over time coral buried by sediments will form into limestone (like the animal shells). .
And then get processed in a quarry and used by us (MORE)
