Question

explain the formation of coal​

Answer 1

Answer:

Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

Explanation:

• Plant matter in mires and wetlands, such as ferns, shrubs, vines, trees, and algae dies and accumulates on the surface. Initially, the organic matter is decomposed by bacteria, yielding carbon dioxide and methane.

• The plant matter becomes buried and is no longer exposed to air. Anaerobic bacteria then start to decompose the material. Burial and accumulation can occur for several thousands of years, producing several meters of partially decayed plant matter known as peat.

• When this peat is deeply buried, water and other compounds are squeezed out from the increasing pressure, and the lowest quality of coal, lignite, begins to form.

• Continued burial, resulting in increasing pressures and temperatures, causes this low quality lignite coal to be transformed into higher quality "black coals". the first lignite becomes sub-bituminous coal, then bituminous coal, and finally the highest quality anthracite coal. As these transformations occur, the amount of water and other compounds in the coal decreases, and the coal becomes denser. Along with this comes a higher carbon concentration.

Answer 2

• Carbon, hydrogen, oxygen, nitrogen, sulphur, moisture, and noncombustible mineral materials are all found in coal (i.e., ash).
• Carbon is released into the atmosphere when coal is burnt. Coal burning produces no fluorinated gases.
• Vegetable detritus accumulates in specific settings, resulting in coal formation.
• It's a challenging task to get coal from the mines.
• The soil that has accumulated above the coal deposit is first removed. Explosives are employed to break apart the coal once it has been exposed.
• The coal is put into carts and hauled to the surface in this manner.
• Mines are accessed and exited through an elevator that travels vertically through the shaft.
• Coal mines are prone to catching fire, and putting one out is extremely tough.
• Coal is formed over a million years. Natural calamities such as floods, tsunamis, landslides, and other natural disasters caused lush forests in wetlands on Earth millions of years ago.
• Over time, more dirt was accumulating in these woods.
• Biodegradation, mainly via mud or acidic water, protected these plants from oxidation.
• Carbon gets trapped in the buried sediments as a result of this process.
• Carbonization is the process through which plant converts to carbon dioxide. It's a long and winding road ahead of you.
