What is the origin of the coal?
It is generally accepted that most coals formed from plants that grew in and adjacent to swamps in warm, humid regions. Material derived from these plants accumulated in low-lying areas that remained wet most of the time and was converted to peat through the activity of microorganisms.
What is the original source of the coal energy?
the sun
Coal is called a fossil fuel because it was made from plants that were once alive! Since coal comes from plants, and plants get their energy from the sun, the energy in coal also came from the sun. The coal we use today took millions of years to form.
What is the origin of coal and petroleum?
Coal and petroleum are formed as a result of degradation of ancient plant life which lived millions of years ago. These dead plant matter started to pile up, eventually forming a substance called peat. Over time, heat and pressure from geological processes transformed these materials into coal.
What is made from coal?
Coal also has a myriad of other uses, including in cement production, carbon fibers and foams, medicines, tars, synthetic petroleum-based fuels, and home and commercial heating.
What is the origin of coal quizlet?
coal is formed from dead/decayed plants that are fossilized for millions of years and is applied heat and pressure.
Why is coal the main source of energy?
Coal is a major source of energy in the production of electrical power using steam generation. In addition, gasification and liquefaction of coal produce gaseous and liquid fuels that can be easily transported (e.g., by pipeline) and conveniently stored in tanks.
Why is coal the best source of energy?
It is by far cheaper than nuclear, natural gas, oil. Coal also provides a stable source of energy (no Arab oil embargoes, no sudden scarcity like you experience with natural gas) and there is a very plentiful supply both in the U.S. and in other foreign countries.
What is the origin of coal and its percentage of carbon?
Heat and pressure produced chemical and physical changes in the plant layers which forced out oxygen and left rich carbon deposits. In time, material that had been plants became coal. These classifications are based on the amount of carbon, oxygen, and hydrogen present in the coal.
Why coal is the best energy source?
Cheapest source of energy. It is by far cheaper than nuclear, natural gas, oil. Coal also provides a stable source of energy (no Arab oil embargoes, no sudden scarcity like you experience with natural gas) and there is a very plentiful supply both in the U.S. and in other foreign countries.
Where is coal found quizlet?
It is a combustible black or dark brown rock consisting mainly of carbonized plant matter, found mainly in underground deposits and widely used as fuel. Where does Coal come from? The energy in coal comes from the energy stored by plants that lived hundreds of millions of years ago in swampy forests.
What is coal and how is it formed quizlet?
coal is fossil fuel that have been transformed by heat and pressure overtime that it transform in to a carbon rich rock. It formed by heat and pressure turning the sediment that deposited over plants in to hydrocarbons.
How is coal made by nature?
Coal is made from trees or plants that decayed on the ground for millions of years. The remains of various plants and trees then mixed with the other components of the ground and eventually going through several natural processes making them more like solid rocks.
How long does it take to make coal?
We have been taught that it takes millions of years for coal to form. However, in a laboratory, researchers have made low-quality coal in less than one year. It takes eleven years to produce coal that is very close to “Natural” coal.
Is coal a rock, mineral or fossil?
Coal is a sedimentary rock . Coal is an energy mineral (legally a mineral, scientifically a rock). Coal is fossil fuel (because it is derived from fossil plant remains). Coal is a solid hydrocarbon (because it consists mostly of carbon, hydrogen, and oxygen; in contrast, oil is a liquid hydrocarbon, and natural gas is a gaseous hydrocarbon).
Where did coal come from?
Coal is a combustible sedimentary rock. It was formed from plant remains that have been compacted, hardened and chemically altered over geologic time. The coal deposits although exist in nearly every region, but commercially exploitable deposits occur in Europe, Asia, North America and Australia.
