Coal is being formed from decayed fossils and remains. These materials are smashed, “compacted” together until their chemicals merge together from the pressure of the compacting this is also how diamonds form from coal just more heat and more pressure. This process is called compaction.

Why is compaction important in the formation of coal?
Compaction happens when sediments are packed tightly together. Cementation binds the sediments together to form a rock. Dead plants buried at the bottoms of swamps can form peat. Over millions of years, the peat can become coal.

What is the formation process of coal?
There are four stages in coal formation: peat, lignite, bituminous and anthracite. The stage depends upon the conditions to which the plant remains are subjected after they were buried – the greater the pressure and heat, the higher the rank of coal.

What characteristic of swamps is important for the formation of coal?
The formation of coal begins in areas of swampy wetlands where groundwater is near or slightly above the topsoil. Because of this, the flora present produces organic matter quickly – faster in fact than it can be decomposed. In these areas, layers of organic matter are accumulated and then buried.

How is peat coal formed?
Peat is the first step in the formation of coal, and slowly becomes lignite after pressure and temperature increase as sediment is piled on top of the partially decaying organic matter. In order to be turned into coal, the peat must be buried from 4-10 km deep by sediment.

What is needed to form coal?
Coal is formed when dead plant matter submerged in swamp environments is subjected to the geological forces of heat and pressure over hundreds of millions of years. Over time, the plant matter transforms from moist, low-carbon peat, to coal, an energy- and carbon-dense black or brownish-black sedimentary rock.

What are the conditions required for the formation of fossil fuels?
Fossil fuels are compound mixtures made of fossilized plant and animal remnants from millions of years ago. The creation of fossil fuels—either oil, natural gas, or coal—from these fossils is determined by the type of fossil, the amount of heat, and the amount of pressure.

Which of the following is important for the formation of coal?
Physical alterations of peat create the pressure and make the environment suitable for coal formation. Chemical alterations, on the other hand, lead to the accumulation of peat and prevents it from bacterial decay. Thus, both these processes help in the coal formation.

What conditions are needed for coal to form?
Coal beds consist of altered plant remains. When forested swamps died, they sank below the water and began the process of coal formation. However, more than a heavy growth of vegetation is needed for the formation of coal. The debris must be buried, compressed and protected from erosion.

Does coal come from the swamp?
Coal formation Coal comes from the energy stored by land plants from swamps that lived hundreds of millions of years ago. For millions of years, a layer of dead plants at the bottom of the swamps was covered by layers of water and dirt, trapping the energy of the dead plants.

Where does coal often form once there was swamps?
COAL IS A FOSSIL FUEL As the plants died, they sank to the bottom of the swamps. Over the years, thick layers of plants were covered by dirt and water. They were packed down by the weight. After a long time, the heat and pressure changed the plants into coal.

How is peat formed?
Peat forms when plant material does not fully decay in acidic and anaerobic conditions. It is composed mainly of wetland vegetation: principally bog plants including mosses, sedges, and shrubs.

How and where is peat formed?
Peat formation is the result of incomplete decomposition of the remains of plants growing in waterlogged conditions. This may happen in standing water (lakes or margins of slow flowing rivers) or under consistently high rainfall (upland or mountain regions).

Is coal made from peat?
The precursor to coal is peat. Peat is a soft, organic material consisting of partly decayed plant and mineral matter. When peat is placed under high pressure and heat, it undergoes physical and chemical changes (coalification) to become coal.
