Plant matter. 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.
Coal usually forms from buried tissues of higher plants. Most of Earth’s coal originated as trees, ferns, and other tropical forest plants that lived in a warmer time in our history. That’s why the world’s coal beds are found on land.
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.
noun A formation in which there are strata of coal; a bed or stratum of coal.
Coal deposits are found in sedimentary rock basins, where they appear as successive layers, or seams, sandwiched between strata of sandstone and shale. There are more than 2,000 coal-bearing sedimentary basins distributed around the world.
Much of the bituminous coal of eastern North America and Europe is Carboniferous in age. Most coals in Siberia, eastern Asia, and Australia are of Permian origin.
Coal and petroleum are formed as a result of degradation of ancient plant life which lived millions of years ago. These dead plant matter started to pile up, eventually forming a substance called peat. Over time, heat and pressure from geological processes transformed these materials into coal.
Coal is very old. The formation of coal spans the geologic ages and is still being formed today, just very slowly. Below, a coal slab shows the footprints of a dinosaur (the footprints where made during the peat stage but were preserved during the coalification process).
Coal is called a fossil fuel because it was made from plants that were once alive! Since coal comes from plants, and plants get their energy from the sun, the energy in coal also came from the sun. The coal we use today took millions of years to form.
peat bogs
Like other ranks of coal, bituminous coal forms from thick accumulations of dead plant material that are buried faster than they can decay. This usually takes place in peat bogs, where falling plant debris is submerged in standing water.
Answer and Explanation:
Coal beds in Antarctica are proof that at one time the continent of Antarctica was much warmer and contained huge quantities of plant matter.
Coal fires occur in operating coal mines, abandoned coal mines and waste coal piles. They sometimes start because of a nearby blaze, but they can also ignite through spontaneous combustion: certain minerals in the coal, such as sulfides and pyrites, can oxidize and in the process generate enough heat to cause a fire.
The world has proven reserves equivalent to 133.1 times its annual consumption. This means it has about 133 years of coal left (at current consumption levels and excluding unproven reserves).
Coal was one of man’s earliest sources of heat and light. The Chinese were known to have used it more than 3,000 years ago. The first recorded discovery of coal in this country was by French explorers on the Illinois River in 1679, and the earliest recorded commercial mining occurred near Richmond, Virginia, in 1748.
Depending on tectonic forces, such as the stability of the earth’s crust in the area or an uplift in mountain ranges, the peat deposits ended up deep underground or closer to the surface.
Coal is a fossil fuel, formed from vegetation, which has been consolidated between other rock strata and altered by the combined effects of pressure and heat over millions of years to form coal seams. The energy we get from coal today comes from the energy that plants absorbed from the sun millions of years ago.

–Petroleum is called ‘Black Gold’ due to the following reasons- -When petroleum is extracted from the ground, the crude oil is black in colour. -It is compared to gold due to its high commercial value and due to its valuable properties.
Crude oil, natural gas and coal are fossil fuels. … The oil and gas then migrates through the pores in the rocks to eventually collect in reservoirs. Coal comes mainly from dead plants which have been buried and compacted beneath sediments.
Coal deposits are primarily found in eastern and south-central India. Jharkhand, Odisha, and Chhattisgarh accounted for almost 70% of the total known coal reserves in India.
Fuels like coal, petroleum, natural gas are formed from the dead remains of plants and animals buried under the earth millions of years ago, so these are known as fossil fuels.
COAL: There are coal deposits found along the coast of Antarctica. … These deposits were formed between 35 million and 55 million years ago when Antarctica was covered by ancient swamps. Coal forms in swamps as plants die and are buried before they can be completely decomposed.
