Cemented shells of marine organisms form which kind of sedimentary rock?
The cemented shells of marine organisms form limestone, which is a type of sedimentary rock. Limestone is predominantly composed of the mineral calcite and can contain fossilized remains of shells and other marine organisms.
Which kind of sedimentary rock is formed by cemented shells of marine organisms?
Limestone is a sedimentary rock formed by cemented shells of marine organisms such as corals and shellfish. The accumulation of these shells, along with other calcium carbonate materials, over time creates limestone rock.
When marine organisms die their shells eventually become what rock?
When marine organisms die, their shells can eventually become limestone rock through a process called lithification. This process involves the compaction and cementation of the shells over time, creating a solid rock formation.
How was the rock made?
Chalk is a form of limestone composed of the skeletons and secretions of small marine organisms.
What type of sedimentary rock is made from dead organisms?
Limestone is a sedimentary rock that is often formed from the remains of dead marine organisms such as shells and coral. This type of rock is composed mainly of calcium carbonate.
Many caves in the eastern US were formed with what kind of sedimentary rock that contained remains of ancient marine life?
I believe it is Bioclastic sedimentary rock--coquina although it was formed by shells of marine organisms.
Which mineral-calcite or quartz- is foind in limestone rock?
Limestone mainly consists of the minerals calcite and aragonite. It is considered to be a sedimentary rock with marine organisms.
What happened in the past to cause limestone to look the way it does now?
Limestone is a sedimentary rock formed from the compression of marine organisms over millions of years. These organisms, like coral and shells, accumulated on the ocean floor and were compressed into solid rock by pressure and time. The presence of calcium carbonate in these marine organisms is what gives limestone its characteristic appearance.
What is an organic sedimentary rock composed of cemented shells?
An organic sedimentary rock composed of cemented shells is called limestone. Limestone is primarily made up of the mineral calcite, which is derived from the shells of marine organisms like coral and mollusks. Over time, these shells accumulate and compress to form solid rock.
Where does limestone originate from?
Limestone originates from the accumulation of marine organisms such as coral and shells over millions of years, forming sedimentary rock.
Is Oil formed from the accumulation of dead marine organisms and found in sedimentary rock layers?
Yes, oil is formed from the accumulation of dead marine organisms over millions of years. As these organisms decompose and are buried under layers of sediment, the high pressure and temperature transform them into oil. Oil is typically found in sedimentary rock layers where it has accumulated over time.
What rock is made from organisms that live under water?
Limestone is a rock primarily composed of calcium carbonate, which often forms from the accumulation of the shells and skeletons of marine organisms, such as corals and mollusks. Over time, these organic materials can compact and cement together to create limestone deposits. Other similar rocks include chalk, a soft, white form of limestone made from microscopic marine organisms.
