So, accumulating ten feet of plant debris will take a long time. About ten feet of plant debris will compact into just one foot of coal. The weight of these materials compacts the plant debris and aids in its transformation into coal. These are typically washed into the swamp by a flooding river. Once a thick layer of plant debris is formed, it must be buried by sediments such as mud or sand. To form the thick layer of plant debris required to produce a coal seam, the rate of plant debris accumulation must be greater than the rate of decay. In addition, insects and other organisms that might consume the plant debris on land do not survive well under water in an oxygen-deficient environment. This lack of oxygen allows the plant debris to persist. Swamp waters are usually deficient in oxygen, which would react with the plant debris and cause it to decay. When a plant dies and falls into the swamp, the standing water of the swamp protects it from decay. Coal forms from the accumulation of plant debris, usually in a swamp environment.
