Formation of Coal

Overlaying of sediments over the burial results in the formation of fossil fuels due to exposure to high pressure for a very long period of time. The 3 main types of Fossil Fuels are Coal, Oil & Natural Gas. Natural coal is formed due to the burial of plants and animals. Petroleum and natural gas are a result of the buried marine life.

15.6: Coal

Coal is classified into four main types, or ranks depending on the types and amounts of carbon present and on the amount of heat energy the coal can produce, including anthracite, bituminous, subbituminous, and lignite (highest to lowest ranked, pictured in Figure (PageIndex{1}). Figure (PageIndex{1}) Different types of coal.

16.1: Types of Fossil Fuels and Formation

There are several different types of coal ranging in quality (figure (PageIndex{b})). The more heat and pressure that coal undergoes during formation, the greater is its fuel value and the more desirable is the coal. The general sequence of a swamp turning into the various stages of coal are as follows:

Fossil | Department of Energy

Fossil energy sources, including oil, coal and natural gas, are non-renewable resources that formed when prehistoric plants and animals died and were gradually buried by layers of rock.Over millions of years, different types of fossil fuels formed -- depending on what combination of organic matter was present, how long it was buried and what temperature …
