How does fossilifrous limestone form?
From the shells and skeletons of dead sea creatures.
What type of setting does organic limestone form?
Organic limestone forms in marine settings where marine organisms produce calcium carbonate shells and skeletons that accumulate and solidify over time. This occurs in warm, shallow waters such as coral reefs or lagoons.
Which rock was formed from skeleton and shells of sea animals and plants?
Limestone is a rock that is formed from the skeletal remains of sea animals and plants. It is primarily composed of calcium carbonate, which is derived from the shells and skeletons of marine organisms such as coral, mollusks, and foraminifera. Over time, these remains accumulate and become compacted and cemented to form limestone rock.
Which sedimentary rock is composed of fragmented skeletons and shells of sea organismscompacted and cemented together?
Limestone is a sedimentary rock composed of fragmented skeletons and shells of sea organisms. These fragments are compacted and cemented together over time to form the rock.
A mineral that forms in seawater from the skeletons of sea creatures?
A mineral that forms in seawater from the skeletons of sea creatures is calcium carbonate, often found in the form of aragonite or calcite. These minerals are produced by marine organisms such as corals, mollusks, and certain plankton as they create their shells and skeletons. Upon death, these organisms contribute to sediment that eventually compacts and can form limestone or other sedimentary rocks. This process plays a critical role in the carbon cycle and the geological carbon sequestration of the oceans.
What type of rock is Limestone made from Shells?
carbonaceous shells form limestone which in this case is a bio-chemical sedimentary rock
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.
Did shale come from limestone?
No. Limestone and shale are sedimentary rocks the form by different processes. Limestone is a biological sedimentary rock that forms from the carbonate shells of organisms. Shale is a clastic sedimentary rock the forms from the settling of fine-grained particles of mostly silicate minerals.
What does sedimentary rock form from?
Plant and animal waste, shells and skeletons
What is organic limestone?
Rock that is made from cemented animal bones and shells is what organic limestone is.Specifically, the term "organic" indicates that the rock in question contains parts from a once-living animal. Hard parts such as bones and shells may cement together. The minerals - such as calcite - which make up these hard parts will form into limestone. In comparison, chert will form from the silica-based skeletons of microorganisms that die in such watery environments as lakes and oceans.
How do coral reefs form rocks?
basic answer, they suck up calcium and other elements from the water to build their skeletons. when they die, another coral builds upon the dead skeletons.
Where does limestone form and what are the key factors that contribute to its formation?
Limestone forms in marine environments, such as shallow seas and coral reefs, where calcium carbonate accumulates from the shells and skeletons of marine organisms. Key factors contributing to its formation include the presence of calcium carbonate-secreting organisms, warm and clear waters, and minimal sediment input that could bury the accumulating calcium carbonate.
