Detailed explanation-1: -Coal is fossil fuel or fuel that comes from the remains of prehistoric plants or animals. The formation of coal occurs over millions of years via a process known as carbonation. In this process, dead vegetation is converted into carbon-rich coal under very high temperature and pressure.

Detailed explanation-2: -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.

Detailed explanation-3: -Coal is formed when dead plant matter submerged in swamp environments is subjected to the geological forces of heat and pressure over hundreds of millions of years. Over time, the plant matter transforms from moist, low-carbon peat, to coal, an energy-and carbon-dense black or brownish-black sedimentary rock.

Detailed explanation-4: -coal, oil, or natural gas. Fossil fuels formed from the remains of ancient plants and animals.

Detailed explanation-5: -Oil, natural gas, and coal were the resultant fossil fuels (see Figure 1 for an example of coal formation). Each fossil fuel is formed slightly different due to organic matter composition, the amount of time the fuel remains buried, and the temperature and pressure conditions of the geographic region.
