Coal

Definition

Coal is a combustible black or brownish-black sedimentary rock formed from decomposed plant material that has been subjected to heat and pressure over millions of years. It serves as a major source of energy and has played a crucial role in the industrial development of various regions, including its extraction and use in electricity generation and steel production.
