Carbonate rocks precipitate from ____.

Question

Quizplus · Accepted Answer

Carbonate rocks form through precipitation of minerals, such as calcite or aragonite, from water that is enriched in calcium and carbonate ions. These ions can come from a variety of sources, such as carbon dioxide dissolved in seawater or the weathering of limestone. However, the precipitation process itself does not involve the physical incorporation of planktonic organisms or fossil material, which are typically associated with the organic build-up of sedimentary rocks like limestone. Therefore, option B is the best choice as it directly relates to the precipitation process of carbonate rocks.
