The most common calcium compound on Earth is calcium carbonate, found in limestone and the fossilised remnants of early sea life; gypsum, anhydrite, fluorite, and apatite are also sources of calcium.
Soil additive made from pulverized limestone or chalk.
The primary active component is calcium carbonate.
Chemical decomposition caused by heat.
Calcium carbonate (limestone or chalk) decomposes into calcium oxide and carbon dioxide when heated. The chemical reaction is as follows:
Natural void in the ground, specifically a space large enough for a human to enter.
Limestone caves are often adorned with calcium carbonate formations produced through slow precipitation.
Outer covering of a hard-shelled egg and of some forms of eggs with soft outer coats.
The chicken eggshell is 95-97% calcium carbonate crystals, which are stabilized by a protein matrix.
Substance which neutralizes stomach acidity and is used to relieve heartburn, indigestion or an upset stomach.
Rarely, long-term use of calcium carbonate may cause kidney stones.
Form of terrestrial limestone deposited around mineral springs, especially hot springs.
It is formed by a process of rapid precipitation of calcium carbonate, often at the mouth of a hot spring or in a limestone cave.
Hard, protective outer layer usually created by an animal that lives in the sea.
A seashell is usually the exoskeleton of an invertebrate (an animal without a backbone), and is typically composed of calcium carbonate or chitin.
Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO3).
Aragonite is a carbonate mineral, one of the three most common naturally occurring crystal forms of calcium carbonate, CaCO3 (the other forms being the minerals calcite and vaterite).
