Coal
density of coal
Coal is a combustible rock that forms from the accumulation of organic debris such as spores, leaves, and wood. It forms within swampy deposits known as peat bogs. As peat bogs are buried and deepened with layers of sediment, the remains of organic material undergo a chemical process. This process ......
