(Jaleb) Well not exactally it is formed by pressure but not by fire.
Coal is formed by the burial and heating of large quantities of organic matter. Brown coal is a low-grade form of coal, formed by moderate burial and pressure. Black coal is formed by increasing pressure and temperature, removing more of the volatiles and resulting in a more carbon-rich coal.
Millions of years of pressure and heat turned decaying animals and plants into coal.
No one invented coal it was discovered. It is dead animals/trees who have been under alot of pressure for millions of years and formed coal
anthracite coal is the metamorphic form of bituminous coal which is the sedimentary form. in other words it has been heated under pressure.
Wood is formed from plant matter like trees; coal is a type of rock that is formed under great pressure over millions of years.
Anthracite, the hardest coal, forms from the greatest pressure.

Anthracite, a variety of coal, is formed from the metamorphosis of bituminous coal through natural processes of heat and pressure deep underground.
