Coal Rank Progression. Coal is a sedimentary deposit laid down in water that comprises preserved plant material from ages past. Over time a great thickness of plant material accumulates that is broken down into peat. This represents a storehouse of organic matter produced via photosynthesis by plants using the suns energy.Read More
