It is a sedimentary rock, and is therefore formed when layers of sand/mud and animal remains fall to the bottom of an ocean or lake, and slowly decompose and are crushed together by the weight of the water, forming a rock. This is why sedimentary rocks often contain fossils- its those dead animals.

∙ 11y agoRemember that limestone is the result from natural processes in the ocean and other marine waters, so it is not intentionally created by any one organism. When any shelled sea creature dies, its shell collects near the bottom of the water. Here, it decays and becomes a part of the rock known as limestone. So, limestone is made of decayed calcium, or calcite.

Almost - but a chemicalelement cannot decay! The primary mineral of this sedimentary rock is calcite,calcium carbonate, which is a chemical compund(CaCO3). Limestone will also form from the compound precipitating from solution in the sea-water - which isalso the source for that taken up by the shell-fish, although many species secrete it as aragonite rather than calcite.

Is limestone an organic and chemical sedimentary rock?
Limestone made from shells would be an organic sedimentary rock.
Why is limestone called a organic rock?
Limestone is not generally referred to as an organic rock. It is primarily composed of calcium carbonate, which is a mineral. However, in some cases, limestone can contain remnants of organic matter such as shells, coral, or other marine organisms, which can give it a slightly organic origin. This is why some people may refer to limestone as an organic rock.
Is limestone made from clastic organis or chemical?
A purely chemical sedimentary limestone would contain no fossil remnants, organic limestone would.
What organic sedimentary rock is made of microscopic shells?
Limestone and chalk.
What are two important important organic rocks?
Limestone and coal are two important organic rocks.
Is limestone from shells chemical organic or clastic?
Limestone made from shells would be an organic sedimentary rock.
Is limestone an organic and chemical sedimentary rock?
Limestone made from shells would be an organic sedimentary rock.
Is limestone made by shells organic?
No. Carbonates are considered to be inorganic.

Is limestone that is made from shells a organic rock?
Yes, mostly gravel from a landslide, and organic rocks
Is limestone made from clastic organis or chemical?
A purely chemical sedimentary limestone would contain no fossil remnants, organic limestone would.
What organic sedimentary rock is made of microscopic shells?
Limestone and chalk.
What is an inorganic sediment for earth science?
coal or limestone. coal is made of once living organisms so it's organic. limestone is make from the shells of little organisms so it's also organic.
What rock is a deposit of organic limestone on land?
Chalk is one limestone formed from organic processes. There are others.
Sediment is made from pieces of?
Sediment is made from clay, gravel, some organic matter, weathered limestone and basalt.
Is sandstone organic?
Sandstone is not an organic sedimentary rock, but limestone is.
How many types of limestone are there?
Limestone can be classified as organic, chemical, or bioclastic.
