Coal
Coal is a combustible black or brownish-black sedimentary rock formed from the remains of plant life, often used as a fuel source for Energy production. It is composed primarily of carbon, along with various other elements such as hydrogen, oxygen, and sulfur. The formation of coal occurs over millions of years, as plant matter is subjected to high temperatures and pressures, transforming it into a carbon-rich substance. Coal has been a crucial component of Industrialization, powering factories, trains, and other machinery. However, its use has also been linked to Environmental pollution and Climate change, prompting a shift towards more sustainable energy sources like Renewable energy and Solar power.
