  • How is coal formed?

    In time, material that had been plants became coal Coals are classified into three main ranks, or types: lignite, bituminous coal, and anthracite These classifications are based on the amount of carbon, oxygen, and hydrogen present in the coal Coal is defined as a readily combustible rock containing more than 50% by weight of carbon...
