Coal is an abundant natural resource that can be used as a source of energy, as a chemical source from which numerous synthetic compounds (, dyes, oils, waxes, pharmaceuticals, and pesticides) can be derived, and in the production of coke for metallurgical processes. Coal is a major source of energy in the production of electrical power ...

Coal is a solid fossil fuel created from vegetation that was squeezed by pressure for millions of years. During the first part of the Cenozoic Era, which began about 65 million years ago, the last of the seas that had covered North Dakota drained away. Layer after layer of rotted trees and other vegetation piled up in swamps over millions of ...

Petroleum is formed from the remains of organisms that are buried deep inside the crust of our earth for millions of years. These organisms are of various types like plants and animals and they got decomposed slowly over the course of time. Due to extreme pressure and heat and also due to lack of air, these remains got transformed into petroleum.

Coal beds consist of altered plant remains. When forested swamps died, they sank below the water and began the process of coal formation. However, more than a heavy growth of vegetation is needed for the formation of coal. The debris must be buried, compressed and protected from erosion.

A diagram is given illustrating the extent of change in the plant material, in comparison with diagenetic and metamorphic intensity. Since coal beds generally include various proportions of the diverse materials resulting from the three processes, practical classification of coal is intimately related to the part each process has played.

Coal formation is a continuing process (some of our newest coal is a mere 1 million years old). Today, in areas such as the Great Dismal Swamp of North Carolina and ia, the Okefenokee Swamp of Georgia, and the Everglades in Florida, plant life decays and subsides, eventually to be covered by silts and sands and other matter. Perhaps millions

sedimentary rock, rock formed at or near Earth's surface by the accumulation and lithification of sediment (detrital rock) or by the precipitation from solution at normal surface temperatures (chemical rock). Sedimentary rocks are the most common rocks exposed on Earth's surface but are only a minor constituent of the entire crust, which is dominated by igneous and metamorphic rocks.

Answer. Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial ...

Subbituminous coal can be formed at a very low temperature of 35℃ to 80℃ while anthracite is formed under a very high temperature of at least 180℃ to 245℃. Also, favourable geology does not only contribute to the formation of coal but other factors like the presence of oxygen also contribute to the high coal deposition.

The most favorable conditions for the formation of coal occurred 360 million to 290 million years ago, during the Carboniferous ("coalbearing") Period.

Physical and chemical changes took place as a result of heat and temperature extracting out all oxygen leaving the plant layers with carbonrich content, thus resulting in the formation of coal over a period of time.

Th e process of converting coal into electricity has multiple steps and is similar to the process used to convert oil and natural gas into electricity: 1. A machine called a pulverizer grinds the coal into a fi ne powder. 2. Th e coal powder mixes with hot air, which helps the coal burn more effi ciently, and the mixture moves to the furnace. 3.

Solution. Fossil fuels are formed by decomposing dead and decaying plant or animal matter underground for millions of years. When any plant or animal dies, soil bacteria start decomposing the matter which was gradually buried by the layers of rock in the earth's crust which increases the heat and pressure inside, and as a result of heat, fossil ...

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.
