Global warming - Carbon dioxide | Britannica
Global warming - Global warming - Carbon dioxide: Of the greenhouse gases, carbon dioxide (CO2) is the most significant. Natural sources of atmospheric CO2 include outgassing from volcanoes, the coustion and natural decay of organic matter, and respiration by aerobic (oxygen-using) organisms. These sources are balanced, on average, by a set of physical, chemical, or biological processes

Calcium carbonate - Wikipedia
Calcium carbonate is a chemical compound with the formula Ca CO 3.It is a common substance found in rocks as the minerals calcite and aragonite (most notably as limestone, which is a type of sedimentary rock consisting mainly of calcite) and is the main component of pearls and the shells of marine organisms, snails, and eggs., and eggs.
What is Calcium Carbonate? - Industrial Minerals …
Large deposits of marble are found in North America and in Europe; e.g., in Carrara, Italy, the home of the pure white "statuario" from which Michelangelo created his sculptures. Calcium carbonate, as it is used for industrial purposes, is extracted by mining or quarrying.

What exactly is rust? - NCH Europe
Most of us know rust as a reddish-brown flaky coat on metal and think nothing more of it, however rust is the term commonly used for the corrosion and oxidation of iron and its alloys, such as steel. Technically rust is Hydrated Iron (III) Oxide, also known as iron oxide (Fe²O³), as it is caused when iron reacts with oxygen and water - this reaction is known as oxidizing.
