What rocks was formed skeleton and shells of sea animals and plats in the ocean?
limestone. A rock made up mainly of the shells or fragments of shells of megascopic (clams, oysters, snails) animals is a coquina. If the rock is composed of the shells (tests) of microscopic plants and animals it may be called chalk. Limestone can be a hardened chemical precipitate of CaCO3 without an organic source, and take many forms: oolite for example.
What is the difference of phytoplakton and plakton?
Plankton, is a microscopic plant found in water. Phytoplankton, is a microscopic plant, made up of microscopic plants.
Is oil called a fossil fuel because it is made from the remains of microscopic animals and plants?
yes
What are Organic rocks made from dead plants and animals?
Soil is made up of a mixture of decayed organic material, living organisms, and minerals. The organic materials come from dead plants like banana peels and last year's leaves. The living organisms range in size from moles to microscopic bacteria. The minerals come from the rocks underground, which are classified as bedrock. Soil is made up of many layers. This is because plants grow on top of the soil and rocks are found underground. The type of soil that forms in a region will depend upon the climate, the bedrock underground, or the plants growing there. Although all soils are made of these basic ingredients, there are many variations. In forests for example, the soil may be deep, rich, and may have a dark brown color. In sandy areas the soil will be dry with a dusty gray color. In tropical regions the soil is often very deep and bright red.

How is a limestone cave formed?
Limestone is a sedimentary rock made up of calcite (CaCO3) as its main mineral. Some limestones were formed by chemical deposition and others by the accumulation of shells from minute sea creatures. Many invertebrate animals (animals with no backbones) take calcite from sea water to construct their shells. When they die the shells fall to the sea bed. Areas where there is little deposition of mud or sand will be ideal for the formation of limestone. One type of limestone which is very pure is called chalk, but most other limestones contain variable amounts of mud or sand or other material.
What organic sedimentary rock is made of microscopic shells?

Is limestone an organic and chemical sedimentary rock?
Limestone made from shells would be an organic sedimentary rock.
Is coquina a metamorphic rock?
It is a sedimentary rock made almost entirely of bones and shells.
A type of organic sedimentary rock made of the mineral calcite and formed largely from the shells of ocean animals?
Any Type Of Limestone
What class of sedimentary rocks are made of fragments from rocksminerals and shells?
The class of sedimentary rocks that are made of fragments from rock minerals and shells is called alabaster. It is a fine-grained sedimentary rock.
What kind of rock is made of sedimentary rock?
The answer is organic sedimentary rock.
What sedimentary rocks are made of fragments of rocks minerals and shells?
Bioclastic sedimentary rocks.
How organic sedimentary rock made?
Organic sedimentary rocks are formed from the accumulation of once living things. Coal is an example of a sedimentary rock.
What kind of sedimentary rock is made from the remains of organisms or fossils?
Clastic sedimentary rocks, like conglomerate and sandstone.
