Unlike the types of lime called quicklime (calcium oxide ... Limestone-based chalk is produced in many areas all across the United States which tends to make it more widely available. Conversely, marble is a harder, purer marking material that tends to flow faster in a chalker. Marble chalk is produced in more mountainous areas of the US, primarily in northern Georgia and western Colorado.The main component of chalk is calcium carbonate (CaCO 3), a form of limestone.

Chalk is a pure white limestone formed from the remains of tiny marine organisms (plankton) that lived and died in clear warm seas that covered much of Britain around 70 to 100 million years ago. When they died, they fell to the bottom in a rain of fine white mud. As chalk formed from the mud, layers and lumps of hard ...Chalk, composed of limestone, represents statues in this activity. Limestone contains calcium carbonate (CaCO 3), which reacts chemically with acids, causing it to deteriorate or erode. The acid causes the calcium (Ca) and carbonate (CO 3) in the limestone to separate into calcium and carbon dioxide gas (CO 2).Much of the state of Texas exposes a fossil-rich layer of Cretaceous chalk, which is a soft limestone.
