Sedimentary rock made up of the remains of living things?
This type of sedimentary rock is called organic sedimentary rock. It forms from the accumulation and compaction of plant and animal remains, such as shells, skeletons, and plant materials. Common examples include limestone, coal, and chalk.
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.
Sedimentary rocks that are formed partially by animals and plants are called what?
Sedimentary rocks that are formed partially by animals and plants are called organic sedimentary rocks. These rocks are formed from the accumulation and lithification of the remains or traces of once-living organisms. An example of an organic sedimentary rock is limestone, which is formed from the accumulation of marine organisms' shells and skeletons.
How does bioclastic rock form?
Bioclastic rocks form when organic material, such as shells or calcareous skeletons of marine organisms, accumulate and are compacted over time. These materials are often cemented together by minerals, forming a solid rock. Factors such as wave action, currents, and biological activity contribute to the formation of bioclastic rocks.
Does the same process form all types of sedimentary rock?
#1. The classic route begins with the weathering and erosion of sedimentary, igneous, or metamorphic rocks. Through these processes, larger rock is broken up into smaller particles which are transported by moving water, ice, gravity or wind, and deposited at the bottom of a lake, a river delta, an ocean, or similar location where further movement is restricted or slowed down. The rock particles can range in size from boulders to clay particles less than .002 mm in diameter. If these rock particles are covered by additional particles, eventually the weight from above will start the process of lithification. Lithification is the compaction and cementation of particles which form rock. Compaction squeezes out the fluids and space that exist between the particles, and cementation results when the fluids that are squeezed out are replaced with minerals that were in the fluids. Once cementation occurs, the new sedimentary rock has been formed. Rocks formed in this manner include sandstone, shale, mudstone, breccia, and conglomerate and are called clastic sedimentary rocks. #2. Organic sedimentary rocks like some limestones and coal are formed largely from the remains of once living organisms. Chalk and fossiliferous limestones are formed from the skeletons of marine organisms. Coal is formed from vegetation that previously existed in swampy and marshy waterlogged soils which prevented their full decay after their death. As their remains piled up and were covered by more and more deposits, they gradually underwent compaction and cementation as described in #1. above. #3. Sedimentary rocks can also form when minerals in a body of water have so saturated the water that they precipitate out, like a cloud that is so full of moisture that it pours out rain. Some limestones are formed in this manner as the mineral calcite precipitates out of a saturated solution and undergoes the process of compaction and cementation. The supersaturated solutions can also be caused by evaporation of a body of water high in mineral content. As the water evaporates, the mineral percentage of the remaining solution becomes higher and higher, until the mineral crystallizes. Rocks such as rock salt and rock gypsum are formed in this manner. Sedimentation from precipitation and evaporation form rocks called chemical sedimentary rocks.
Sedimentary rock made up of the remains of living things?

Which sedimentary rock is made of Skeletal remains of organisms?
Limestones are sedimentary rocks made of skeletal remains. Limestones are recognizable because they react with Acid. Crystalline limestone are micro skeletons with large visible crystals. Micritic limestone is lithographic limestone and it is basically fine grained mud with micro-skeletons. Fossiliferous limestone is made with whole fossils in my experience mostly shells. Coquina is parts of skeletons pressed together. The difference between coquina and fossiliferous is that coquina doesn't have whole fossils. Lastly there is chalk. This is a lot of microorganisms remains pressed together.
What is the only sedmertary rock type that can be formed from things that were once alive?
The only sedimentary rock type that can be formed from things that were once alive is organic sedimentary rock. It is primarily composed of the remains of plants and animals, such as shells, bones, and plant matter. These organic materials undergo compaction and cementation over time to form rocks like limestone and coal.
What are the six steps of forming a sedimentary rock?
1.step Weathering-breaking rocks apart. 2.step Erosion-taking rocks away. 3.step Deposition-landing in a new destination. 4.step Sedimentary-new layers are formed pressing down on each other. 5.step Comentation-pieces of rocks are glued together.7
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.
How do organic sedimentary rocks forms?
from dead plants
What is lithified of tiny marine organisms with skeletons composed of silica?
Diatoms are tiny marine organisms with skeletons made of silica. When these diatom skeletons accumulate and become cemented together over time, they form a type of sedimentary rock known as diatomite or diatomaceous earth.

How do sedimentary rocks formed?
Are formed by the deposition of material at the Earth's surface and within bodies of water.Sedimentation is the collective name for processes that cause mineral and/or organic particles to settle and accumulate or minerals to precipitate from a solution.
