Answer 2

200 and 300 million years ago
growth of huge tropical ferns and giant trees, which grew and died in vast swamp areas. The dead plants fell into the boggy waters, which tended to exclude oxygen and bacteria, so that they only partially decomposed to produce a peat-like material. This fossilized plant debris was the beginning of coal, but only the beginning.
Vegetation continued to grow forming vast, thick peat beds which were later to turn into coal.
swamp gradually became submerged by shallow seas, where they were covered by sediment. these sediments would later become sedimentary rock. This cycle of swamp followed by submersion was often repeated a number of times, so that a sequence of horizontal bands of peat and inorganic, sedimentary rock was built up. This formed the first stage, called the biochemical stage. Coal formation occurred in other geologic periods as well.
What this is saying is first it began with decaying vegetation it continued to on like this for thousands of years
bands of peat were altered by the action of pressure and temperature during the second, or geochemical stage, to form the various kinds of coal found today.
The study of fossils is called paleontology. The creation of coal from fossils is part of geology.
that is why coal is called a fossil fuel.
