Anthracite, the hardest coal, forms from the greatest pressure.

Diamonds are not made from coal. Diamonds are formed deep within the earth's mantle under enormous pressure and extreme heat, from carbon.

Coal and solar energy are alike because they both are having to do with energy and they are both formed ny the sun or have sun in them. Although, solar energy is renewable and coal is non-renewable they both have some similarities.
it is formed by being burned which causes heat, which can also be converted into motion energy.
The energy in coal is stored as chemical potential energy.When the coal is burned, this chemical energy is converted to heat. The boiler converts this thermal energy into pressure of the steam.The pressure energy in the steam is then converted into rotating mechanical energy using the turbine. As the turbine spins the generator, the generator converts this into electrical energy.
(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.
Anthracite, a variety of coal, is formed from the metamorphosis of bituminous coal through natural processes of heat and pressure deep underground.

Millions of years of pressure and heat turned decaying animals and plants into coal.
coal, carbons. Formed by intense pressure.
anthracite coal is the metamorphic form of bituminous coal which is the sedimentary form. in other words it has been heated under pressure.
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.
