Briefly explain how coal forms. What will be an ideal response?
Coal forms from the accumulation of generations of dead plants in a swamp. The plants never decay
fully because there is no oxygen for the decomposers to use. As the plants are buried by sediments and
other plants, they are lithified and become coal.
