Because fossil fuels take hundreds of millions of years to form under the Earth's surface. It will take another million years for more to be produced, so we only have a limited supply. Eventually, more fossils will be made, but by then we will have run out by how much we use them now. If we stop …using them so much than we wont die like we are going to. So essentially, all fossil fuels are considered non-renewable. ( Full Answer )
because they aren't going to never going to be more after it is used up!
The source of energy for fossil fuels is the hydrocarbons they contain which burn with oxygen to release a lot of heat. I don'y know about refining coal.
it is made from once living things when the pangea on the earth moved away
Coal, petroleum,and natural gas, are called fossil fuels becausethey were formed millions of years ago, during the Carboniferousperiod.
Both of them are because they evolved from little tiny creatures millions of years ago
because fossil fuels are a finit resource and some day in the not to distant future we will run out of it.
Coal, like oil, is made/produced through thousand of years of fossils being compressed and heated in the earth to turn into coal and oil.
The energy stored in coal (and indeed all fossil fuels) is ancient sunlight. This is how it works:- As you know plants need CO2 form the air and sunlight and water to undergo the biochemical process called 'photosynthesis'. Photosynthesis converts the CO2, and Water into sugars which are then …used by the plant to make wood and oxygen - the plant grows. You will all be familiar with the fact that wood will burn using the oxygen in the air to produce heat, water and CO2. The heat given off is the sunlight energy that the plant trapped and stored as it 'photosynthesised'. Plants therefore affectively trap and store sunlight as chemical energy. If many plants form a layer and this layer gets covered with soil and buried, the plants turn into fossils and if there are enough of them they form a layer of biological matter. Time and heat in the earth turns this biological matter into coal (and oil and gas). The coal, oil or gas will burn in air to produce heat, water and CO2. The heat is the sunlight that the plants trapped when they were living all those millions of years ago - fossil sunlight! ------------------------------------------------------------------------------------------------------ Coal contains (stores) chemical energy in the form of Carbon/Hydrogen compounds. It contains various impurities as well. When heated, these Carbon/Hydrogen compounds and some of the impurities will react with oxygen producing carbon dioxide (CO 2 ), water, and other chemicals (depending on the original constituents), releasing much of it's stored energy as heat. ----------------------------------------------------------------------------------------------------------- ( Full Answer )
The earth has a limited supply of oil, gas and coal at least inpractical terms. It takes millions of years for the earth totransform dead organic material into these fossil fuels. The supplyof fossil fuels we are using today come from organic materialsburied generally at least 20 million years ago, …and some that wereburied more than 200 million years ago. This is different from renewable materials, like wood, that can beplanted again, so the supply can be renewed. Fossil fuels are considered non-renewable sources of energy becausewhen they are burnt, they are finished. When the last barrel of oilhas been pumped out of the ground there is no more. It isnon-renewable. Similarly with coal and natural gas. The origins of most fossil fuels is over 60 million years old, fromthe dinosaur age (Mesozoic Era) and the carbon age (within thePaleozoic Era). When that supply is gone it is gone forever so itis a non renewable resource. Renewable fuel grows back or can not be depleted. For example: . Wind can't be stopped it will always blow. . Trees grow back if we allow them. . Oil is under the ground and once it is gone it is gone. Because fossil fuels take hundreds of millions of years to formunder the Earth's surface. It will take another million years formore to be produced, so we only have a limited supply. Eventually, more fossils will be made, but by then we will have runout by how much we use them now. If we stop using them so much thanwe wont die like we are going to. So essentially, all fossil fuels are considered non-renewable. Fossil fuels are considered nonrenewable resources because, fossilsfuels are made from the remains of dead plants or animals. It takesmore than a million years for the fuels to form from the fossils.It is a long process. They take millions of years to form. Humans cannot produce them or cause them to reproduce. Trees, corn and other organic matter for ethanol can be grown. Oil and coal are a product of the planet and take millions of years to form. ( Full Answer )
They have been formed over millions of years as dead animals and plants have been crushed and compressed by the weight of the ever-increasing material on top of them. Their age, along with the fact that they are unrenewable sources i.e. they will never be re-made, leads to the fact that they are fos…sil fuels. ( Full Answer )
Yes coal, oil and natural gas are non-renewable fossil fuels because it takes a long time to make them, millions of years. Yes, fossil fuels are nonrenewable because it takes million of years of fossil fuel to form.
The major producers of coal in the world, in order: . China . USA . India . Australia . Russia . South Africa . Germany . Indonesia . Poland
First of all, you spelled dose wrong. "Does" is the correct spelling. And fossil fuels and coals make electricity because those are what power the electricity to function properly.
I believe you mean coal bed gas or coal bed methane which is a fossil fuel.
Because if you ise say a gallon of them that we call "A" than you will never the same "A" again because you used it
The following percentages are approximate and do vary significantlyfrom sample to sample (even when from the same vein): . 80% carbon . 5% hydrogen . 5% oxygen . 1.5% nitrogen . 0.75% (low) to 1.5% (high) sulfur Any element on the periodic table can and does occur in minor(parts per thousand)… or trace (parts per million or billion)amounts (including uranium).

No, they are not considered a renewable resource. Fossil fuels are non-renewable because they were make millions of years ago, and when we use them up, as we may do soon, especially oil, there is no more left. Renewable means it comes back, like the power of the sun.
Plants use the energy from the sun to make food. They depend on sunlight to power chemical reactions vital for life. In a number of instances, plants that lived long ago died, and their remains built up in a layer or layers. As more and more overburden was deposited on top of the layer, compression …and time changed the "plant material" into coal. This gives rise to the idea that the fossil fuel coal contains energy from the sun. ( Full Answer )
Fossil fuels, coal and oil won't be found in Antarctica, because The Antarctic Treaty bans drilling or mineral exploration.
Yes, Bituminous coal is fossil fuel, formed from the debris of plant matters buried under the earth millions of years ago and underwent several physio-chemical changes to acquire the state.
Coal, oil, natural gas, etc. are forms of petroleum and yes, petroleum in all forms, is a fossil fuel.
fossil fuels does have coal in it because when the smoke comes up, coal in already in it!!! I am not 100% sure this is right.............
they both are made using natural gas and come from either mines or out of the ground
Coal powers some electricity plants in China.Some of China's coal comes to us in the u.s. However when we use coal it powers fossil fuel plants and nuclear plants around the u.s. and even the world.
Coal is a hydrocarbon rock formed from geologically trapped deposits of plant matter which were formed over millions of years. The oldest coal deposits are as much as 350 million years old; the youngest are about 15 million years old. Deposits that are younger than that do not have all the physical …properties of coal--they are more like peat beds. Since it takes millions of years for coal to form, it is considered a fossil fuel, rather than a renewable resource. ( Full Answer )
When you burn something, you are causing an exothermic reaction to occur. When that heat is released from the reaction, is causes more to burn, keeping the exothermic reaction going.
Because we can only use them once . When we've used them, they've gone. This is the opposite of renewable sources of energy like sunshine or wind power which we can keep on using over and over.
Fossil fuels are considered a non-renewable resource because they take millions of years to form under earths pressure. So once there gone you have to wait a long time before you can have them again.
Coal is formed over millions of years by pressure and heat on decomposed vegetation accumulated in shallow swamps, the result is a sedimentary carbonaceous rock known as coal...
Biomass fuels are meant to mimic or replace the functions of fossil fuels. The Department of Energy defines biomass as "any plant derived organic matter available on a renewable basis." These organic matter consist of products such as wood, crops, alcohol fuels, landfill gas, agricultural waste and …residues, and garbage. Biomass fuels are just beginning to be developed and their potential is still being cultivated.. ( Full Answer )
Because they contain carbon, a chemical element present in all lifeforms on earth. They are formed from ancient plants and animals, I'm sure wikipedia can give you some more information.
the simple answer is this, they are all found it the earths crust or diameter
Not usually (usually the exact opposite, in fact). It would be possible to call some kind of fuel hybrid that for some reason burned in a particularly clean way or produced more energy for the same carbon emission level "green", but even then it would only be green compared to standard fossil fuel …standards. ( Full Answer )
It takes too long for these resources to be replaced. We're talking millions if not billions of years. So in practical sense, in our lifetime, or in the foreseable future, they are non renewable.
I believe you are asking is what scientific endeavors or challenging tasks exist related to fossil fuels. One challenging task is to find new sources of fossil fuels and to find best means to produce the discovered fuels. To do this requires people skilled in the following disciplines: Geophysics …Geology Mechanical Engineering Chemical Engineering Petroleum Engineering - including drilling, production and reservoir. A second challenging task is to set regulations and procedures so fossil fuels can be produced in a safe manner and to reduce the impact to the environment. Scientists study the impact to the environment, particularly air pollution to burning gasoline in our cars. This requires environmentalists, environmental engineers, marine biologists, lawyers (to write laws and regulations) and the other engineering disciplines mentioned above. You may find many of the challenges to the future of fossil fuels by doing a google search on the internet. ( Full Answer )
Most likely because fossil fuels are not minerals. They are ultimately composed of organic matter which came from living things that died and became buried under sediment. Through a lot of time and a great amount of pressure the fossil fuels were developed. This is also why fossil fuels are consider…ed non-renewable resources because it takes so long to make them. That's all :) JAE HERMOSA ( Full Answer )
Fossil fuels-including coal, natural gas, and oil-are formed from the fossilized remains of prehistoric plants and animals, and fossil fuels provide about 95% of the world's total energy.

When dead animals die, after many years they start becoming part of the earth like soil when natural causes cause pile on top of them. After many years they turn to coal. It is actually a renewable source since everything dies but since it takes so long to make its considered non-renewable. Sorry if… any information is wrong. :P ( Full Answer )
Coz burning coal produces lots of heat which is released into atmosphere. It also generated flyash polluitng the surrounding environment.
Carbon dioxide is produced at an unsustainable rate. This builds up in the greenhouse gases in the atmosphere and is causing global warming.
Fossilized wood, also known as petrified wood is more akin to stone than that of coal or the original wood, filled with mostly silicates such as quartz. As such it is no longer technically would and hence it will not burn. A fossil fuel takes centuries of decomposition and compression and is mostl…y carbon or hydrocarbons. Wood however will usually not be allowed to grow even as long as a single century before it is harvested. Also wood is not nearly at the right concentration of carbon to be a viable fossil fuel. Finally, although you would not think it, burning wood is technically environmentally friendly, or at least carbon neutral. For fossil fuels, the process takes too long to match consumption and is finite. Wood upon burning, technically only gives off enough carbon dioxide to be absorbed by the other trees aiding in their growth and as such, allowing them to absorb more CO2. Obviously on the scale of a forest fire or that of the energy industry, the balance is overexploited but even still you would be more enviro concious if you were to burn wood over fossil fuels, which are full of other elements like sulphur. I may have gone off at a tangent but I hope this answer helps. ( Full Answer )
Although it is renewable, it takes so long to do so and we're using it up too fast it's considered non-renewable.
When we factor in the cost of the carbon pollution, and what itwill cost the earth in the future, we can see that the burning offossil fuels (coal, oil and natural gas) is extremely expensive.Just the cleanup from one tropical cyclone costs into the billionsof dollars. Insurance companies are very w…orried about climatechange. ( Full Answer )
Hardly. Use of coal as fuel has been declining since the increase in the use of oil in the late 19th century. The overall consumption of coal has increased over that time, quite a different matter, as the overall consumption of all fuels has increased. But the total consumption of fuels has a smalle…r and smaller use for coal, as other fuel uses increase at a faster rate. Just for a few well known examples. Railway locomotives were almost exclusively operated on coal, yet are now almost exclusively diesel/electric for long haul and electric for urban uses. Homes were by and large heated with coal in urban settings 100 years ago, those have been replaced in the majority by natural gas or electricity, and lesser by oil. Most manufacturing companies worldwide used coal to power machinery, much of that has been replaced with centralized utility plants providing electricity, with less small power plants (satellites) relying on their own power production, yet those that do have converted to oil or gas for fuel. So even though most electricity is produced by coal worldwide, its use is declining in most developed countries. The increase in use of coal in developing countries is more a factor of a total increase in fuel use in those countries. ** in the 1930s and 40s there were thousands of operating coal mines in 34 US states. Today there is less than half as many mines in 26 states. With an increasingly greater percentage of coal being mined in western states like Montana, Wyoming and Utah. Coal is no longer mined north of Pennsylvania in the east. ( Full Answer )
It is decomposed. Coal is also taken out from the depths of the Earth where it is smashed by rocks, lumps of trees and dead and burned animals.
A finite resource is something that can only be consumed once without possibility of being recycled for re-use. Because fossil fuels are burned, they cannot be reused and are therefore a finite resource.
They are produced during the fossilization process of carbon richorganic material. Heat and pressure deep in the earth's crust causechemical changes.
Why are fossil fuels considered to be nonrenewable while biomass fuels are considered to be renewable?
It takes millions of years for organic matter to decay into fossil fuels (oil, natural gas, and coal). It takes just a few weeks to grow biomass and turn it into fuel. Fossil fuels (coal, oil and natural gas) started as organic matter 300 million years ago. They were subjected to intense temperatu…res and pressure and over millions of years turned into coal and oil. So now, when we dig them up and burn them, they are finished. We can only use them once. They are non-renewable. Biomass fuel is really any kind of vegetation that is burnt to produce electricity. Ideally this is residue from other crops, like the remains of sugar cane (bagasse) after they crush out the sugar juice. All these crops can grow quickly, in one season, so they are renewable. We can always grow more. Another advantage of biomass over fossil fuels is that it doesn't contribute to the build up of carbon dioxide in the atmosphere (because when it grows it removes an equivalent amount), but that's another question. A: Fossil Fuel comes from decayed and compressed animal and vegetable matter that was crushed under the ground millions of years ago. When we burn it as coal, oil or natural gas, then that is gone. It doesn't "renew" like sunshine or wind, that is still there after we use it. So all fossil fuels are non-renewable . Biomass is vegetable material that grows quickly, in a season. It absorbs carbon dioxide from the atmosphere, and releases that same carbon when it is burnt, so it is part of the natural carbon cycle. Because we can grow it again quickly, biomass is considered renewable. ( Full Answer )
Notice the word "fossils " this is no mistake. After millions ofyears of heat and pressure the fossils became oil and other fuelsthat we use. Once gone they are gone because we don't have the timethat it took for the death of dinosaurs to make it.
