wood-peat-lignite-subbituminous-bituminous-anthracite The wood is converted to anthracite (coal) through various stages. lignite, subbituminous,bituminous,anthracite are the major coal types formed these are ranked based on the presence of carbon ,hydrogen and oxygen content
Are there any other kinds of coal?

What is the difference in peat bituminous lignite and anthracite?
They are all derived mostly from plants.
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.
Which list presents in correct order forms of coal from the first stage?

What is the difference between lignite and bituminous coal?

Bituminous coal or black coal is a relatively soft coal containing a tarlike substance called bitumen. It is of higher quality than lignite coal but of poorer quality than anthracite. Formation is usually the result of high pressure being exerted on lignite.
Why have anthracite mining rates declined?
Most of the original markets for anthracite were relinquished long ago to natural gas, fuel oil, and other coals, such as bituminous and lignite coal.
As coal forms how does its carbon content change?
It compacts and increases as moisture and volatile hydrocarbons are driven off. Coal has a carbon content between 75 and 90 % , lignite (brown coal) hasn't completed the transformation and contains more moisture and nitrogen than bituminous or anthracite coals. Lignite has about 30 to 40% carbon content.
