KIDS TRIVIA

Detailed explanation-1: -Limestone (calcium carbonate CaCO 3) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of CaCO 3. Limestone forms when these minerals precipitate out of water containing dissolved calcium.

Detailed explanation-2: -Travertine, tufa, caliche, chalk, sparite, and micrite are all varieties of limestone.

Detailed explanation-3: -Limestone is a sedimentary rock, which means it was formed from small particles of rock or stone that have been compacted by pressure. Sedimentary rock is important because it often contains fossils and gives clues about what type of rock was on the Earth long ago.

Detailed explanation-4: -Limestone is usually a biological sedimentary rock, forming from the accumulation of shell, coral, algal, fecal, and other organic debris. It can also form by chemical sedimentary processes, such as the precipitation of calcium carbonate from lake or ocean water.

Detailed explanation-5: -The minerals calcite and dolomite are the main ingredients of limestone. Both are calcium-bearing carbonate minerals, meaning that they contain the chemical elements calcium (symbol Ca), carbon (symbol C) and oxygen (symbol O).
