What is Lime? | Graymont

The lime cycle consists of first burning of limestone to form quicklime. Hydrated lime can then be produced by adding water to the quicklime. At this point, carbon dioxide in the atmosphere or from industrial processes react with hydrated lime to convert it back to limestone. This cycle is called the lime .

Limestone in the geological carbon cycle? | Yahoo Answers

Apr 11, 2011 · Best Answer: CO2 can be pulled out of the atmosphere and dissolved in the world's oceans. The evidence of this is the abundance of creatures who build their shells out of Calcium Carbonate (CaCO3). When the shells are abandoned (or the creature dies) and the shell falls to the seafloor, the CO2 from the atmosphere will soon lithify into the rock, limestone.

Beer stone was a popular kind of limestone for medieval buildings in southern England. Limestone and (to a lesser extent) marble are reactive to acid solutions, making acid rain a significant problem to the preservation of artifacts made from this stone. Many limestone statues and building surfaces have suffered severe damage due to acid rain.

The Carbon Cycle - earthobservatory.nasa.gov

Over time, layers of shells and sediment are cemented together and turn to rock, storing the carbon in stone—limestone and its derivatives. Limestone, or its metamorphic cousin, marble, is rock made primarily of calcium carbonate. These rock types are often formed from the bodies of marine plants and animals, and their shells and skeletons ...
