Coal Facts

 Coal is a black mineral fuel that consists mainly of the element carbon.  In addition to carbon, coal contains a variety of hydrocarbons, often traces of sulfur, and moisture.  Coal occurs as seams (layers in the rock strata) within the Earth's crust.  The depth at which coal seams are found varies enormously.  In some coalfields the seam can lie just below the surface.  Usually, coal seams are buried beneath hundreds of meters of rock.

  The properties (qualities or power) of coal have been known for at least 2,000 years.  However coal was used very little until the Industrial Revolution of the 1700s.  Before this time, firewood and charcoal provided the entire world's energy needs.  During the 1700s, coal quickly replaced charcoal as an industrial (connected with industry) fuel.  In the 1800s, coal provided the driving energy behind the great Age of Steam.  Today, coal is used mainly in the production of electricity.
