WhatsApp: +86 18203695377Answer: Coal is formed when peat is changed physically and chemically. Thisprocess is called coalification. During this process peat undergoes many changes as a result of bacterial decay,heat, and time. Peat deposits contain everything from pristine plant parts,such as roots, bark, spores, etc.
WhatsApp: +86 18203695377Ever wonder where a "fossil fuel" gets its name? Fossil fuels are compound mixtures made of fossilized plant and animal remnants from millions of years ago. The creation of fossil fuels—either oil, natural gas, or coal—from these fossils is determined by the type of fossil, the amount of heat, and the amount of pressure.

WhatsApp: +86 18203695377Fossil fuels are nonrenewable sources of energy formed from the organic matter of plants and microorganisms that lived millions of years ago. The natural resources that typically fall under this category are coal, oil (petroleum), and natural gas. This energy (and CO 2) was originally captured via photosynthesis by living organisms such as plants, algae, and photosynthetic bacteria.
