How is a anthracite coal formed?
anthracite coal is the metamorphic form of bituminous coal which is the sedimentary form. in other words it has been heated under pressure.
What is the density of coal?
Density of Coal may vary, depends on the type (structure) and form. Below are some density of coal : - Coal, Anthracite, solid 1.506 gr/ml - Coal, Anthracite, broken 1.105 gr/ml - Coal, Bituminous, solid 1.346 gr/ml - Coal, Bituminous, broken 0.833 gr/ml
How many forms of coal are there?
Coal is classified into four general categories, or "ranks." They range from lignite through sub-bituminous and bituminous to anthracite, reflecting the progression of individual deposits of coal to increasing heat and pressure. Anthracite coal has the highest carbon content, frequently associated with home heating. Bituminous coal is the most plentiful form of coal in the United States, and is used primarily to generate electricity and make coke for the steel industry. Sub-bituminous coal ranks below bituminous. This coal generally has a lower sulfur content than other types, which makes it attractive for use because it is cleaner burning. Lignite coal is a geologically young coal which has the lowest carbon content, 25-35 percent. Sometimes called brown coal, it is mainly used for electric power generation. Hope it helped :)
Is lignite a form of coal?
Yes. Lignite is also known as brown coal. It is not exactly the same as coal (bituminous or anthracite) but it is near the beginning of the process that makes coal. Lignite has about 1/3 to 1/2 the carbon content of coal.
What are the different names of coal?
The names for the different types of coal depends on the organic content. The coal with the lowest percentage of organic matter is anthracite. (around 10 % organics) Then comes steam coal, bituminous coal. (around 20 %) Lignite is a form of coal with high organic content (around 50 %) Peat is a coal precursor (half way to being coal) (More than 50 %)
What is the deff of anthracite?
Anthracite is metamorphosed bituminous coal, a coal with the highest percentage of carbon of the coal varieties.

Are sandstone and mudstone sedimentary rocks?
no not all of them for example like Bituminous coal or coal, is form by plant remains
Did animals and plants form bituminous coal?
Bituminous coal is largely the product of ancient plant remains, although some animals would have contributed to a very small percentage of its mass.
What is the density of coal?

What is the hardness of the Metamorphic rock?
Depends on which one. Diamond is a metamorphosed coal/carbon that is the hardest natural substance known. Marble is metamorphosed limestone that is much softer. It's safe to say that all metamorphosed rocks are harder than they were in their pre-metamorphosed form.

What are the four stages of coal formation.?
The materials formed at each step of the process are 1) Peat 2) Lignite 3) Sub-Bituminous and Bituminous Coal 4) Anthracite (may also form from oil) The final stage, which most coal does not reach, is graphite or pure carbon.

What is the original form of anthracite coal?
Anthracite forms from the metamorphism of bituminous coal. The metamorphism occurs due to pressures and temperatures from depth of burial or stresses derived from plate movements.
