Accumulated, compacted and altered plants form a sedimentary rock called coal. It is not only a resource of great economic importance, but a rock of intense fascination to the student of earth history. Although coal forms less than one percent of the sedimentary rock record, it is of foremost importance to the Bible-believing geologist. Here is where he finds one of his strongest geological ...

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed if dead plant matter decays into peat and over millions of years the heat and pressure of deep burial converts the peat into coal.

History of the use of coal In ancient times. The discovery of the use of fire helped to distinguish humans from other animals.Early fuels were primarily wood (and charcoal derived from it), straw, and dried dung. References to the early uses of coal are meagre.

Coal is a remnant of past life—a sort of fossil—that began as a tangle of plants on the surface of ancient Earth. In the process of photosynthesis, plants use sunlight, water and CO 2 to grow, releasing oxygen to the atmosphere. When they die and decay, the carbon in their tissues usually returns to the atmosphere as CO 2 or a gas called methane (CH 4).

The history of coal mining goes back thousands of years. It became important in the Industrial Revolution of the 19th and 20th centuries, when it was primarily used to power steam engines, heat buildings and generate electricity. Coal mining continues as an important economic activity today. Compared to wood fuels, coal yields a higher amount of energy per mass and can often be obtained in ...

Coal - Origin of coal: It is generally accepted that most coals formed from plants that grew in and adjacent to swamps in warm, humid regions. Material derived from these plants accumulated in low-lying areas that remained wet most of the time and was converted to peat through the activity of microorganisms. (It should be noted that peat can occur in temperate regions [e.g., Ireland and the ...

Coal Origin and Properties . It is generally accepted that coal originated from plant debris including ferns, trees, bark, leaves, roots and seeds some of which accumulated and settled in swamps. This unconsolidated accumulation of plant remains is called peat. Peat is being formed today in marshes and bogs.

Carbonaceous material accounts for more than 50 percent of coal's weight and more than 70 percent of its volume. Coal is widely used as a fuel, and its combustion products are used as raw material for a variety of products including cement, asphalt, wallboard and plastics.
