Peat is effectively a low-grade coal. The difference is that the plant material has been compacted under less pressure, and for less time. Here's the process:
- Plants thrive during an interglacial period, or because of a circumstantial warm breeze giving the right conditions. The best conditions are in marshy deltas.
- For whatever reason, the plants all die, and the dead, decomposing material is covered before it has been totally degraded, sealing it from oxygen.
- Over tens of thousands of years, layers of material build up on top of the material, building downward pressure on it, as well as heat. This pressure increases the proportion of carbon in the material.
- Eventually, the now peat has become a fairly solid material. Over hundreds of thousands of years, it will become coal.
The peat may surface at some point because of tectonic forces causing uplift, or some other cause of exposure to the surface.

What mineral has a structure and a chemical composition that indicate the conditions under which it formed?
Peat
What are the stages of peat?
The bog is drained. The peat is harvested. The peat is transported. The peat is marketed. >They are the 4 stages of peat.
Second stage soft brown rock formed by layers of sand and mud that covers peat?
I am just researching this for my daughther and the answer is ... lignite
Where can peat be found?
Peat occurs in former bogs and swamps. Ireland is famous for its peat.
What is the leading theory of the formation of fossil fuels?
Fossil fuels are believed to have formed from the underground heating and compression of thick layers of dead vegetation formed many centuries ago. An example of this process can be seen from the formation of peat from layers of plant material beneath peat bogs. The release of methane from swamps is another example of the genral process.
Is peat found in swamps?
Yes, peat is found in swamps. Peat is formed in swamps. Moss is found hanging from trees in swamps. Have you heard the term "peat moss"........
Is Peat thought to be the original material from which coals are formed?
yes
How were the Norfolk broads formed?
They were formed by peat digging and the sea levels rising and flooding the pits!
What is a peat bog?
A peat bog is a type of wetland characterized by the accumulation of peat, which is made up of decayed organic matter like dead plants. Peat bogs are important for storing carbon, regulating water flow, and providing habitat for unique plant and animal species. They are found in cool, damp climates around the world.
What mineral has a structure and a chemical composition that indicate the conditions under which it formed?
Peat
What is formed when pressure sqeezes moisture out of peat?
Dried peat. Only after subsequent layers of sediments have been deposited on top, year after year, century after century, eon after eon, will the pressure lithify the peat into coal.
Where is coal begin to form from?
Coal is formed from plants, which turned into peat, then lignite, then coal.
What do peat brown coal and black coal have in common?
They are all formed from the sedimentation of plant matter.
How is coal created and where does coal it come from?
coal is created by the deposition and compaction of huge plant(organic) material deposited into a basin,with the increasing depth the high rank of coal is formed. The order is:- peat>lignite>bituminous>anthracite Peat is formed at shallow depth and on moving downward anthracite is formed at greater depth.
What is the difference between peat based compost and peat free compost?
Peat adds acid. So, if you need to add acid to your soil, you want to use something with peat. We added peat to our blueberry plantings. If you don't need the acid, then get the peat-free stuff. Peat based compost,as the name suggests, contains peat. Peat free compost does not contain peat but some other organic matter. This excercise is driven by the Green lobby who fear that the planet will run out of peat and implode.
What are the stages of peat?
The bog is drained. The peat is harvested. The peat is transported. The peat is marketed. >They are the 4 stages of peat.
How does peat become coal?
Peat is formed where thick deposits of sphagnum mosses accumulate. The aerobic environment at the base of the peat bog preserves the biomass while the overhead burden compresses it. Peat can be burned as a fuel, but it is still essentially plant material (like wood). Coal is formed when an accumulated biomass of plant material is subsequently covered by sediments and then buried deep in the earth. This burial process compresses the material much much more and the heat in the earth alters the chemistry of the biomass, forming new chemicals that were not made by the plants and turning the biomass into a rock - COAL. There are no plants left, only their fossilised impressions.
