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 else can I help you with?
Is chalk made of diatoms?
No, chalk is not made of diatoms. Chalk is primarily composed of calcite, a mineral form of calcium carbonate, which originates from the skeletal remains of marine organisms like coccolithophores and foraminifera. Diatoms, on the other hand, are a type of algae with silica-based cell walls, and they contribute to different types of sedimentary rocks. While both chalk and diatomaceous earth are formed from the remains of microscopic organisms, their compositions and origins differ significantly.
Is chalk made of microplankton?
No, chalk is primarily composed of calcium carbonate, a mineral made up of the skeletal remains of plankton and other marine organisms. Microplankton are tiny organisms found in the ocean, but they are not the main component of chalk.
What is a sedimentary rock made fro the shells of dead sea creatures called?
A sedimentary rock made from the shells of dead sea creatures is called limestone. This rock forms primarily from the accumulation of calcium carbonate, which is derived from the shells and skeletal remains of marine organisms. Over time, these materials are compacted and cemented together, leading to the formation of limestone. Other types of sedimentary rocks can also include similar organic materials, but limestone is the most common associated with marine shells.
What are the remains of once-living orgainismsfound in sedimentary rocks?
All fossils are found in sedimentary rocks. Some sedimentary rocks are made of nothing but fossils such as chalk. A creature ( microscopic or larger) skeleton is deposited after death usually on the ocean floor. Sediments cover it, and over time turns into a fossil.
Group of sedimentary rock made up of dissolved minerals or the remians of living things?
Chemical sedimentary rocks form from dissolved minerals in water, such as limestone made from calcium carbonate. On the other hand, organic sedimentary rocks, like coal or limestone made from the remains of dead organisms, are created from the accumulation and compaction of organic material over time.
What kind of sedimentary rock is made from the remains of organisms or fossils?
Clastic sedimentary rocks, like conglomerate and sandstone.
Sedimentary rocks formed from the remains of once-living things are?
Organic sedimentary rocks, such as limestone and coal, are formed from the remains of once-living things. Limestone is primarily made of calcium carbonate from the shells and skeletal remains of marine organisms, while coal forms from the buildup of plant material in swampy environments over millions of years.
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.
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.
What is a good sentence for limestone?
My kitchen counter is made from limestone.
Is limestone made up of fragments of granitic and andesitic rocks?
No. Limestone is formed from precipitated calcite or from the shells or skeletal remains of marine organisms.
Is chalk made of diatoms?
No, chalk is not made of diatoms. Chalk is primarily composed of calcite, a mineral form of calcium carbonate, which originates from the skeletal remains of marine organisms like coccolithophores and foraminifera. Diatoms, on the other hand, are a type of algae with silica-based cell walls, and they contribute to different types of sedimentary rocks. While both chalk and diatomaceous earth are formed from the remains of microscopic organisms, their compositions and origins differ significantly.
A mountain in the desert is found to be made from the remains of ancient ocean organisms Which type of rock makes up the mountain?
The mountain is likely made of sedimentary rock, such as limestone or sandstone, that formed from the accumulation and compaction of the remains of ancient ocean organisms over millions of years.
Where is limestone made?
Like most other sedimentary rocks, limestone is composed of grains; however, most grains in limestone are skeletal fragments of marine organisms such as coral or foraminifera.
Is chalk made of microplankton?
No, chalk is primarily composed of calcium carbonate, a mineral made up of the skeletal remains of plankton and other marine organisms. Microplankton are tiny organisms found in the ocean, but they are not the main component of chalk.
What is the huge mass of limestone made of?
Limestone is composed of the skeletal remains of minute sea creatures. The layers are then subjected to compression and, over a very long time, hardened into a sedimentary rock.
What rock is made by the planets remains?
sedimentary rock
