Le Charbon
Le charbon est une roche sédimentaire combustible, riche en carbone, de couleur noire ou marron foncé, formée à partir de la dégradation partielle de la matière organique des végétaux. Il est exploité dans des mines, appelées charbonnages. Souvent appelé houille, il était autrefois appelé charbon de terre en opposition au charbon de bois. Source : wikipedia
