Let us learn how coal formed
Coal is called a fossil fuel because its energy was captured around 260 million years ago during a geological period called the Permian. During the Permian, our coal mines of today were broad, flat areas of swamps located on the banks of ancient rivers. The plants that grew in these swamps dropped a large amount of leaves, branches, and seeds into the swamp borders as part of the natural cycle of growth into K over many thousands of years, the swamp environment transformed this decaying plant material into a spongy substance called paint.
If this paint remained uncovered, it finished the cane and oxidize. However, if large amounts of rain fell, mud, rocks and silt were washed down over the peak, burying and compacting it deep on the ground. Four. Erupting volcanos would vary the feet on the layers of ash. Whenever the peak became very, the plant life on the surface would reestablish and begin the process over again. Over time, the earth's geothermal heat worked on the compact and heat to drive off water and other volatile like hydrogen, nitrogen, and oxygen. This heat gradually matured the peat into hard chunks of carbon material that we now know today as coal.
