Sedimentary Rock

Coal

Coal is a combustible black or brownish-black sedimentary rock that is primarily composed of carbon, along with various other elements such as hydrogen, sulfur, oxygen, and nitrogen. It is formed from the remains of plants that lived and died millions of years ago, undergoing a process of heat and pressure over time. Coal is widely used as a fuel source for electricity generation and industrial processes due to its high energy content.

Uses: Electricity generation, steel production, cement manufacturing, industrial heating.

Chemical Composition: Primarily carbon, with smaller amounts of hydrogen, sulfur, oxygen, and nitrogen.
