Plant growth layers onto itself but doesn't decompose quickly creating a peat bog. The peat builds up in the bog, layer by layer compressing into lignite (brown coal). This continues decomposing (anaerobically)and solidifying into semi bituminous (like asphalt), bituminous (soft), semi anthracite or anthracite (hard) coal, depending on pressure, moisture and mineral content of the process. The gasses of decomposition are largely lost in this natural process.
Sometimes this process (due to the type of plant) will decompose into bitumen (tar) or oil deposits which, due to the covering material, traps the gasses of decomposition (natural gas) into pockets, which is why it is most often found when drilling for oil.

What is the source of coal energy?
Dead marsh plants. The majority of coal (and the best grades: bituminous and anthracite) is from plants that died during the Carboniferous (this was before the first dinosaurs lived). Small amounts of very low grade coal (lignite and peat) are much more recent (with some still forming now).
The first stage in the information of coal is?
Rotting vegetation is overlaid by more rotting vegetation or other material. This is compressed by the mass above and form peat. Compression of the peat continues and form lignite (brown coal) Compression continues on the lignite to form coal (clack shiny rock) Compression may continue to form anthracite , the hardest form of coal . NB with each compression watert/moisture is expelled, so coal and anthracite are very dry.
What are the five steps of coal formation?
The first step is Peat, The second step is lignite, The third step is Bitimunous, and the fourth step is Anthracrite and Their is no Fifth step.
How is coal created?
I agree with your correspondent 'Wiki User'. Coal is being formed today. Its first stage is peat formation, found on moorlands in the UK. As more material lies over it, it becomes compressed and begins to fry out. At this stage it is lignite. Continued compression changes the lignite into coal, a black bright shiny carboniferous rock. Continued compression the coal becomes anthracite. A very hard bright coal, that burns with a hot flame.
What was coal before it was made in to coal?
First plants, then dead plant material, and finally lignite.
Which list presents in correct order forms of coal from the first stage?
peat, lignite, bituminous, anthracite.
Which list presents in the correct order forms of coal from the first stage of development to the last stage of development?
The correct order of forms of coal from the first stage of development to the last stage of development is peat, lignite, bituminous, anthracite. Peat is the first stage and is the least carbon-rich, while anthracite is the last stage and is the most carbon-rich form of coal.
In the correct order forms of coal from the first stage of development to the last stage of development?
peat, lignite, bituminouse, anthracite....
In what correct order represents forms of coal from the first stage of development to the last stage of development?

Why is coal an unusual sedimentary rock?
First of all coal is not an unusual sedimentary rock, it is very abundant for the time being. The following is a tutorial from the supplied web site: Coal is clearly made up of lots of compressed bits of dead plants. But when we walk around in the world we usually see old bits of wood and leaves decaying and rotting away (that is, getting eaten by bacteria, insects, and all sorts of organisms involved in decay and recycling of organic matter). For thick layers of plant stuff to get fossilized as coal, something must be going on. Coal Formation starts with accumulation of organic matter (bits of dead plants) in a low oxygen setting such as a peat bog. The organic matter accumulates and forms a bed of peat. The peat bed gets buried by other sediments and under heat and pressure begins to transform to a low grade coal - a Lignite. More heat and pressure further metamorphose the lignite into Bituminous coal. Even more heat and pressure metamorphose the bituminous coal into a nice hard shiny Anthracite. Coal is usually classified into three grades: Lignite, brown coal; Bituminous coal, soft coal; and Anthracite, hard coal. Anthracite is dense, nice and hard, and shiny. The first step in the formation of coal is the accumulation of plant debris in low oxygen conditions, such as in this damp low spot on a moor. Peat exposed to heat and pressure from burial beneath other sediments becomes compressed and chemicaly changes into low grade coals such as this lignite, and under further heat and pressure is converted to higher grade coals. The pressure from overlying sediments that bury a peat bed will compact the coal. Peats transform to low grade lignites when they are compressed to about 20% of their original thickness. Lignite typicaly transforms to bituminous coal as it is compressed further and heated to between 100 and 200°C. This drives much of the water and other volitiles from the coal. Longer exposure to elevated temperature will further drive volatiles from the coal, and drive chemical reactions that produce anthracite. Anthracite coals are typicaly compressed to 5-10% of the orginal thickness of the peat bed, and contain less than 10% water and other volatiles.

What did Jordan Mott make the first stove for?
To burn Anthracite coal
What was coal before it was made in to coal?
First plants, then dead plant material, and finally lignite.
How does coal form?
Coal forms when dead plant material builds up and up to form peat, which is the first step. This is compacted between layers of sedimentary rock, forming a rock called lignite. Then this is compacted even more. Then, heat and pressure deep deep beneath the surface create anthracite, or coal. Coal is a metamorphic rock.
