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...

Iron is usually attracted to a magnet. If a bar of iron is magnetized, One end of the bar will attract one pole of the magnet, and repel the other pole of the magnet. \nCopper, nickel, and zinc are not magnetic. They neither attract or repel a magnet, and they cannot be magnetized.

Well, iron is a metal that doesn't contain carbon. Both are elements i.e. substances that can't be broken down into simpler substances by a chemical reaction. Most of the known elements in the universe are metals eg. aluminium, gold, copper, but the non-metals are more abundant eg. oxygen, hydogen. They are termed metals because of their structure and the way in which they bond to other elements. Maybe by metal you meant metal alloy. Steel is an alloy (mixture) of iron and carbon. I think all alloys of iron have some carbon in them. Don't know if this is what you meant but it was good trying to think about an answer.

There are a couple of naturally occurring ferromagnetic substances, like magnetite (Fe3O4) or nickel-iron from comets, which can act as permanent magnets. The metals iron, nickel and cobalt all exhibit ferromagnetism and can be magnetized. Oxide minerals from these elements may be ferromagnetic, too.

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!

Renewable energy resources may be used directly, or used to create other more convenient forms of energy. Examples of direct use are solar ovens, geothermal heating, and water- and windmills. Examples of indirect use which require energy harvesting are electricity generation through wind turbines or photovoltaic cells (PV cells), or production of fuels such as ethanol from biomass (see alcohol as a fuel). A parameter sometimes used in renewable energy is the tonne of oil equivalent (toe). This is equal to 10,000 Mcal or 41,868 MJ of energy.\n\nIn a sense, renewable energy may be categorised as free energy, although most renewable energy sources would not normally be called "free energy". In engineering, free energy means an energy source available directly from the greater environment and which cannot be expected to be depletable by humans. Renewable energy development is concerned with the use of renewable energy sources by humans. For aspects of renewable energy use in modern societies see Renewable energy development. Modern interest in renewable energy development is linked to concerns about exhaustion of fossil fuels and environmental, social and political risks of extensive use of fossil fuels and nuclear energy.

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).

Coal, Oil, Uranium etc are earths natural resources, and definitly renewable by nature. But are they renewable at the rate we are using them, thats a question to ponder upon! :-)

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.

This is a very complex question.  \n\nThe crude oil reserves in the world are a semi-finite resource.  It takes many millions of years to create the oil that is in the earth. So it is possible to run out.\n\nCurrently there are no plans in place by any nation that could compenate for the depletion of this valuable natural resource.\n\nSome alternatives are being developed. Solar - greatly available but unfortunatly at this time the efficiency of the solar cells is not up to the task of replacing oil.\n\nWind energy - another good option but the size of a wind farm to generate suffient amounts of energy is restrictive. There is not enough land available.\n\nThermal currents on the ocean - Another way to harness solar energy but again VERY inefficient.\n\nNuclear Fission - Already in use on a large scale.  drawbacks are the waste that it produces. EXTREMELY Dangerous radiation that lasts for thousands of years.\n\nNuclear Fussion - This is the power that drives the sun. Couple different versions are being developed but at this time there are not any viable solutions. Possible in the future but currently take a lot of energy to create this engery.\n\nBio Fuels - a great alternative that is already widely in use. again the main drawback here is the amount of land that would be needed to supply the amount of fuel that we use.  We do not have enough at the current time.  We would need almost all of our current farm land to supply the energy need and not have any available for food needs.\n\nFuel Call technology - A very good source of fuel and very clean as well. however the main type of fuel cell is currently the Hydrogen Fuel cell. This is relatively expensive to make and uses some elements that could be also be depleted in the future. also Raw hydrogen is expensive to make. Even though it is thought to be the most abundant element in the universe, most of it is bound up in other compounds. (ie. water, other fuels)\n\nCoal - another very abundant fuel source. Drawback - burns with more polution.\n\nSo overall, the world would definitly change if/when we run out of crude oil.  Things will become more expensive. Polution could get worse unless other fuels can be found that are more enviormentally friendly.  \n\nNo one knows for sure if or when it will run out but there are options. Just be prepared for many different products to come to market that will replace the ones that contain crude oil and its byproducts.

It is a non-renewable fossil fuel.  Oil and natural gas are also fossil fuels.

If you're talking about electricity generated from solar panels, it's not widely done because of how expensive it is to build and construct panels. The material (Germanium or Silicon) alone costs a lot to synthesize.\n\nWind power turns out to be a better alternative, if you consider the costs and benefits. Ocean-tide power may be good source of power too.\n\nNow look up "Dyson Sphere." This is another aspect of tapping solar power; Solar power tapped to the extreme, not for electricity, but for life; A solution for the evergrowing population of mankind. A Dyson Sphere is impossible to construct, but a few hundred years from now it may be possible to create a Dyson Belt, a collection of inhabitable planetoids built and placed in orbit 93 million miles from the sun (the same distance as the Earth).

If a magnet will pick it up it is made (at least partially) of iron and can be recycled.
