What is a classified coal group?
A classified coal group refers to categorizing coal based on its properties and characteristics, such as moisture content, sulfur content, energy content, and caking properties. This classification helps in determining the best use for the coal and its quality for different end uses. Examples of classified coal groups include anthracite, bituminous, and lignite.
What is the grain size of coal?
The grain size of coal can vary, but it typically ranges from fine particles to larger chunks. Coal can be classified based on its grain size as fine, medium, or coarse coal. The grain size of coal can impact its combustion efficiency and handling characteristics.
What rock group does coal belong to?
Anthracite coal is considered metamorphic. All other types are sedimentary.
What type of resource is coal?
Coal is a non-renewable resource that is classified as a fossil fuel. It is formed from the remains of plants and trees that lived millions of years ago and undergo a process of decomposition under high pressure and heat.
Is coal a metal or non-metal?
Coal is a sedimentary rock composed of carbon, sulfur, hydrogen, oxygen and nitrogen. Harder forms of coal can be classified as metamorphic rock. Coal is not a metal.
What type of rock can coal be classified as?
Coal is classified as a sedimentary rock.

What can anthracite be classified as?
Anthracite is a type of coal.
Why are coal and rock limestone classified as organic sedimentary rocks?
The material comprising the rocks coal and limestone are derived from organisms. Therefore, they are classified as organic sedimentary rocks.
What metamorphic rock is currently known as coal?
Anthracite coal is classified as a metamorphic rock. I've included two wikipedia links on this subject.
Coal is not classified as a mineral because it comes?
Coal is not classified as a mineral because it is formed from the remains of plant material, rather than being naturally occurring inorganic solid with a crystalline structure. Minerals are defined as naturally occurring, inorganic substances with a specific chemical composition and crystal structure, which coal does not meet all of these criteria.
What is the grain size of coal?
The grain size of coal can vary, but it typically ranges from fine particles to larger chunks. Coal can be classified based on its grain size as fine, medium, or coarse coal. The grain size of coal can impact its combustion efficiency and handling characteristics.
Is coal metamorphic?
Most coal is sedimentary, but anthracite is bituminous coal that has undergone metamorphosis to become a metamorphic rock.
Why isn't coal classified as a mineral?
Coal is not classified as a mineral because it is formed from organic matter, such as plants, and not from inorganic processes like minerals. Minerals are naturally occurring inorganic substances with a specific chemical composition and crystal structure, while coal is a combustible black or brownish-black sedimentary rock made up of organic materials.
What rock group does coal belong to?
Anthracite coal is considered metamorphic. All other types are sedimentary.
What are resources in Germany?
The only abundant natural recourse that Germany has is coal, all other can be classified as scarce.
Is coal an organic sedimentary rock?
Most coal is classified as an organic sedimentary rock. The exception would be anthracite, which is metamorphosed bituminous coal.
