Explain Why Ores are Non Renewable Sources?
443332
Ores have been deposited over the length of geological history. Most sources of ore must be categorized as non-renewable because the exploitation is way faster than the regeneration rate.\n\nNew ore deposits are formed all the time, e.g. wherever rust carried off by water collects. It takes quite a long time to make these worth exploiting, though.\n\nIn case of riverine deposits (e.g. of gold) it is possible to maintain an equilibrium: the ancients of Kolchis used ram vleeces to collect gold dust in the rivers. As long as the mother lode continued to provide detritus to the river, the gold was collected as a renewable resource.\n\nWhich brings me to theoretical exploitation of volcanic deposits - either from lava deposits, or at the mid-Atlantic ridge. There still is an equilibrium of material subducted in subduction zones like before the Californian coast and material brought up in the Atlantic. One might talk about a renewable resource in this case.

There are a number of natural resources which can be classified under the following main categories : \n\n(a) Inexhaustible (that cannot be finished)\n\n(b) Exhaustible (that can be finished) \n\nRenewable exhaustible (if consumed can replenish). \nNon-renewable exhaustible (if consumed, cannot replenish) \n(a) Inexhaustible Resources cannot be exhausted by human consumption and other uses. These include energy sources like solar radiation, wind power, water power (flowing streams) and tidal power, and substances like sand, clay, air, water in oceans, etc.\n\n{b)     (i) Exhaustible Renewable Resources are those that are naturally replaced or replenished after consumption. Generally these form a cycle. Some examples are water, soil, forests (yeilding wood of other products), vegetation, natural pastures, wild life. The living beings (both animals and plants) reproduce and can thus replace the dying or killed individuals.\n\n(b)     (ii) Exhaustible Non-renewable Resources. These cannot be replaced after use. These are limited in nature. These include minerals (copper, iron etc.), fossil fuels (coal, oil etc.). Even the wild-life species (rare plants and animals) belong to this category, many of them are potentially usable and they contribute in maintaining ecological balance and impart natural beauty. (A species once finished cannot be created again).

Oil is one of the end results of a long, long process of decomposition, heat, pressure, and transformation of molecular structures.  Many people are unaware that there are multiple types of oil resulting form differences in all of the components of the process.\n\nAs a "renewable resource," you are barking up the wrong geologic age.  Once the oil available on Earth is gone - that is, the "petroleum" created through metamorphic processes in deep layers of the planet - human beings may berely live long enough for them to see more.  it takes many millions of years to create oil through purely natural processes.  And the many physical changes in the planet that cause it to begin with, including vast earthquakes, total transformation of the layers of the Earth's crust, extinction of life forms, and other events, suggest that when is more oil made in the distant future, humans might themselves be part of the matter eventually converted into petroleum.\n\nWell, no, that's hardly likely.  Decomposition would prevent that.\n\nBut, anyhow - no, oil is not a practical form of a renweable resource.  It is possible to make synthetic versions of petroleum, or to make alternative fuels that have some of the key features of petroleum, however.\n\nUltimately, humanity may discover that petroleum is much too valuable to just burn.  It is a fundamental ingredient of many kinds of medicines.  It plays a role in various types of chemistry and other applications that may not ever be replaced or reproduced artificially.\n\nAnd humans will never live long enough to get more once it is gone.

Because Mankind has found new ways to combine elements and chemicals into new compounds that have never been present in nature, and would otherwise never form naturally.  Same thing with certain "processes."  What would take nature millions of years to wear down and erode, for example, Man can accomplish in seconds with explosives.

Good grief !!  Try looking up Natural Resources Degree on yahoo search. Good Luck.....all to do with the earth's resources I should think.

Fossil fuels, such as oil, natural gas, or coal, are non-renoewable sources of energy since the supply of them on Earth is pretty much fixed.

In the context of your question,\n\nA resource is a source of material or energy that may be consumed, changed, or dispersed to the point it is no longer easily usable. Examples would be copper ore, oxygen in the atmosphere, helium gas taken from oil wells, water, sand, or even soil. Anything we do consumes or utilizes some sort of resource. Breathing uses oxygen from the air. Copper is used for wiring and piping. Helium is used for scientific research and birthday balloons. Sand is used to make concrete. Water is used for drinking, irrigation, and generating hydroelectric power. Soil is used for growing crops.  None of these are exhaustive lists, just examples. \n\nOil: Oil is a mixture of organic compounds extracted from the earth by drilling. It is created from organic materials deposited in sedimentary rock that are altered by heat, pressure, and biotic processes to create it. \nOil is used to make gasoline, diesel, airplane fuel, plastic, shampoo, rubber, antihistamines, and many other products. \n\nNatural gas: It is an organic gas that is also extracted from the earth by drilling. It is generated by a similar process to that for oil generation. It is used to heat homes, make fertilizer, and some plastics. \n\nWater: Water is found in many forms, but mostly as either fresh or saltwater. Fresh water is used for drinking, irrigation, etc. Saltwater is not as useful directly to man, but is an essential part of our environment as the oceans both support food supplies and have a large effect on the climate. \n\nWood: Wood comes from living organisms- trees. Wood can be used for building many things, including houses. It is used for fuel and is the primary source of fuel in some parts of the world.

they are nonrenewable resources.\nonce they been used once (burned) they finished with and cannot create anymore energy.\nThe world has a limited suply of these nonrenewable energy sources left.\n\nrenewable sources woud include solar (sun) wind and water power as these will never run out

No, there is a fixed amount of iron on the planet.  It is an element.\n\nA renewable resource would be one that you can use and then produce more of like trees, crops, clean water etc...

An ore has minerals or metals suspended in a base, unwanted material that needs to be refined to make the pure mineral or metal usable.\n\nA gem is a crystaline material that has some intrinsic value.

We don’t actually ‘use’ raw materials. When we build something out of iron that iron is still here in Erath and available for re-use. When we burn wood the carbon and water change form, but they still exist in Erath and are available for re-use.\n\nSo the raw materials in anything besides a nuclear reaction can never be finished in any meaningful way. They are still available. At worst they will simply become more expensive to obtain.\n\nSo no, nothing humans can possibly do will cause the end of the world. Humans are like the mites living in the fleas living on the rats living on the turds of the elephant. We are totally insignificant and powerless to alter the world in any way that has any meaning.\n\n>>>> biodiesel is best alternative fuel.\n\nBiodeisel isn’t even a practical alternative fuel. It requires more petroleum to produce a gallon of bioideisel than the biodeisel can actually replace. \n\nEven if it wasn’t a massive waste of petroleum to produce, there simply isn’t enough land in the world to produce enough biodiesel to replace more than a few percent of current petroleum, much less other fuels.

ore is mined, then heated very hot. the rock and metals separate. the slag is filtered off the top.

We live in a world with scarce resources. In other words, wood is scarce, steel is scarce, human labor is scarce; our resources on this planet are not infinite.\n\nWhen these resources are applied to things that are demanded MOST by consumers, you don't have economic waste. \n\nEconomic waste exists when our scarce resources are applied to areas that are NOT in high demand by consumers.\n\nProfits and Losses tell us where resources should be applied. When you see high profits, you see the marketplace providing a signal that this is an area of high demand.\n\nWhen you see large losses, it is also a signal. But this signal says that this is an area of low demand. Resources should be removed and applied to where demand is higher.\n\nIn order to have Profits and Losses, you MUST have Prices.\n\nIn order to have Prices, you MUST have Private Property.\n\nCapitalism is a system that contains Private Property, Prices, and Profits and Losses.\n\nUnder Socialism, there is NO Private Property, hence NO Prices, hence NO Profits and Losses.\n\nIt's obvious why one works, while the other fails.

Coal is actually the world's most plentiful fossil fuel, but it is alos the dirtiest.  \n\nIt is non-renewable.  \n\nCoal mining is difficult and dangerous.  All over the world hundreds of coal miners die every year because of the hazards of mining it.\n\nBurning coal produces emissions of sulphur dioxide, nitrogen oxides, and carbon dioxide which contribute ot acid rain and global warming.\n\nStrip mining, while safer for the miners, destroys large ares of landscape.\n\nCoal fired power stations need huge amounts of fuel, whihc means covering large areas of countryside close to the power station with piles of coal.\n\nI have attached some websites that should give more information.  I hope this helps.

Renewable resources include such energies as wind, solar (sun) power, geothermal (heat from the ground) and hydro (water).  They are beneficial for the Earth because they do not produce harmful emissions and can, theoretically, last forever.  They are often considered a hindrance (or just annoying) to society because they are rarely cheap to harness (or at least not cheaper than fossil fuels) and a suitable infrastructure is not properly in place for such energies.\n\nNon-renewable resources, on the other hand, include such energies as fossil fuels (this is turned from crude oil into gasoline), natural gases (burnt in many processes for energy), wood (this is considered non-renewable if the rate at which it is used is greater than the rate at which it is created), coal (burnt in many processes for energy) and pretty much any Hydrocarbon.  Non-renewable resources are considered useful and valuable because they are generally cheap to use and have been used throughout history.  For this reason, the infrastructure around non-renewable resources is substantially greater than that of its renewable counterpart.  These energies cause a greater problem than they solve because went used, they produce harmful emissions such as carbon dioxide.  These chemicals are detrimental to one’s health and are a contributing factor in the Greenhouse Effect (the leading cause of global warming in the world).\n\nObviously, renewable resources pose a brighter prospect for the future.\n\nI hope this was an informative answer!

It is renewable since warmth from the sun generates new wind all the time.\n\nThis is the opposite of oil.  Oil takes so long to produce that we use it up much faster than it is created in the earth.  We can actually use up all the oil.
