How do you use the word calcareous in a sentence?
People can find a calcareoussubstance in limestone.
Are bits of shells considered as a sediment?
Yes, coral beaches are a sedimentary deposit, much as a sand beach would be. Bits of shell also precipitate out of water to congeal into limestone formations, or the bodies of calcareous coccolithophores settle to form chalk deposits, as in the famous white cliffs of Dover. Limestone is regarded as a sedimentary rock.
List 2 kinds of rock that are easily weathered by carbonic acid?
Limestone Chalk Calcareous sandstone Dolomite
How do calcareous oozes form?
Calcareous oozes form when the calcium carbonate shells and skeletons of marine organisms, such as foraminifera and coccolithophores, accumulate on the ocean floor. Over time, these calcareous remains compact and cement together to form a sediment known as calcareous ooze.
What are calcareous materials?
Calcareous materials are those that contain calcium carbonate or are derived from it. They are commonly found in materials such as limestone, chalk, and marble. These materials are often associated with marine environments and can be important components of natural structures like coral reefs.

What isThe most abundant chemical Sedimentary rock?
The most abundant chemical sedimentary rock is limestone, which is primarily composed of the mineral calcite (calcium carbonate). Limestone forms from the accumulation of marine sediments like shells, coral, and other calcareous materials over time. It is a versatile rock used in construction, agriculture, and industry.
How are the raw materials used in processing cement procured?
Raw materials used in processing cement are,Calcareous materials (limestone)Argillaceous materials (clay)GypsumCoal dust.
Which group of protists forms part of limestone and how?
Foraminifera, a group of single-celled protists with calcareous shells, contribute significantly to limestone formation. When these organisms die, their shells accumulate on the ocean floor and, over geological time, are compacted and cemented together to form limestone rock. This process occurs in marine environments, where the accumulation of foraminiferal remains can lead to extensive limestone deposits.
What would you call the calcium carbonate deposits?
It depends on the context - in geology they maybe called limestone deposits. In a corrosion sitaution they may be called calcareous deposits
What role does carbon dioxide play in forming limestone as a chemical precipitate?
The reaction is:Ca(OH)2 + CO2 = CaCO3 + H2O
