The earth's core is molten iron-nickel, very hot, and yet we burn oil to make heat - does this make sense?

Geothermal heat would help a lot.  First we should be certain that our homes are well insulated.  If everyone was to install a ground water heat pump, it would lower heating bills (and fuel consumption) and make it cheap to cool in the summer.  Heating and cooling are two of our biggest energy demands.  What you are suggesting makes a ton of sense.

Stated here:\n\nhttp://www.windows.ucar.edu/tour/link=/earth/Interior_Structure/interior.html&edu=high\n\nThe Earth's core heats to about 9000 degrees farenheit.  (if you have a different number, use that.)\n\nTo change Farenheit to Kelvin, you use the formula:\n\n\nK = (°F + 459.67) / 1.8\n\nso plugging in 9000 for farenheit, if my calculations are correct, the Earth's core should be about 5255.37 K

I don't think so. The Earths magnetic field is generated by the dynamo effect of the solid Ni-Fe core spinning at a different rate to the liquid Ni-Fe core around it. I can't see how humans can effect that process.\n\nI guess it might be possible to modify the magnetic field locally be producing another field that interferes with it....but I doubt we're doing anything strong enough to do that. The polar shift of the magnetic field is a natural process that has occurred thousands of times.\n\nTo answer 'my girls' question...the earths magnetic field protects us rather than harms us. If it didn't exist, we'd have little protection against the harmful radiation produced by our sun.

An intriguing theory now permeating oil company research staffs suggests that crude oil may actually be a natural inorganic product, not a stepchild of unfathomable time and organic degradation. The theory suggests there may be huge, yet-to-be-discovered reserves of oil at depths that dwarf current world estimates.\n \nThe theory is simple: Crude oil forms as a natural inorganic process which occurs between the mantle and the crust, somewhere between 5 and 20 miles deep. The proposed mechanism is as follows: \n\nMethane (CH4) is a common molecule found in quantity throughout our solar system - huge concentrations exist at great depth in the Earth.\n \nAt the mantle-crust interface, roughly 20,000 feet beneath the surface, rapidly rising streams of compressed methane-based gasses hit pockets of high temperature causing the condensation of heavier hydrocarbons. The product of this condensation is commonly known as crude oil.

Many of us would like to live our live and find out what our purpose is, so it would be rather selfish to KABOOM the the earth. It is the internal Satan we must fight. I believe that the core of the earth is fire for the sake of keeping the oceans stable. I do not believe that he is down there,.. only in a portion of our heart. We have to find solutions to extinguish the devil there.

ok first of all just because one thing the bible says is true,that wouldnt make the entire thing true and second of all,originally the Earth was a ball of molten rock that cooled down.water didnt come around till later(im not sure how though)

3200 Degrees C.\n\n"The outer core, which is responsible for the Earth's magnetic field, contains about 29.3% of the Earth's mass and has an average density of 12200-9900kg/m3 and temperature of 3200 degrees C."\nhttp://www.cobweb.net/~bug2/rock7.htm

Not a this point in our evolution......we do not have the technology to build something that will protect us from the hot temperatures\nof the inner earth.  Your question is puzzeling, am not sure what \nyou have in mind.

HI.  Great questions.  just realised i only got 2 points for answering.  anyway.  Weird magnets aren't they.  they always have a north and a south pole.  Almost like a mini Earth!  at the centre of the earth matter is so supper heated that it almost, but not quite, turns into energy. This raw force changes into a mix of matter and energy, producing and expelling a strong field of power.   When volcanoes were very active in earths early years, quite frequently this strange mix spewed into our atmoshere and solidified quickly.  magnetism was trapped during this process and magnets were born.  strange but very true.

The surface of the Earth turns to molten lava.

our earth would burn due its heat along with the sun's heat

Through some ridiculous idea, scientists have been able to continue their ridiculous campaign to convince you that the core of the Sun is the hottest even though the Sun's halo-like  corona is 300 times hotter.  Sunspots show us an interior of the Sun that is even cooler than the surface, so how can this be if the core is supposed to be even hotter?  Well it isn't, and that's not where light is created and that's not where fusion takes place.\n\nLook into the "electric universe." Do a search for it.

Of course, the inner core is solid. It is the outer core that is fluid. \n\nNo one really knows what is producing heat in the inner core, and in what proportions:\n\n1. radioactive decay\n2. tidal forces heating, due to gravity gradient of moon, sun etc graviational field \n3. exothermic reactions\n4. gravitational energy release as denser materials settle down into the middle\n5. insulation (some of the heat is still primoridial)\n6. frictional forces from movement of materials in the earth\n\nand so on. This is obviously a fairly complicated nonlinear system, and we do not understand all the physics involved.

We do not really understand what causes the earth's magnetic field, but presumably it is caused by electric currents flowing in the earth, possibly as charged pieces of molten metal move around in the outer core. \n\nSo in this way, the earth's field is due to something more like an electromagnet, which is not destroyed by heat, instead of a permanent magnet, which is destroyed by heat.

it is a little of both. yes the earth has heated but weather goes in circular movement. so there are periods of time when the earth heats up and then cools down. yes we are polluting the air and are loosing ozone, but the biggest factor is from methane gas produced by farm animals. we (Christians) are suppose to be good Stewart's of Gods gifts to us. so we need to learn to recycle, conserve and use the planet wisely. one of the things that would help the most is just planting trees. have an cooling effect on earth.

it's the same reason that if you mix oil and water in a glass, the oil will float to the top and the water will sink to the bottom.  oil has a lower density, which makes it lighter.  the heavier water gets pulled down by gravity and it displaces the oil.  since it is a liquid, the molecules of oil and water can move relative to each other.\n\nthe inside of the earth is a liquid, too - it is very hot and all but the outer surface of the earth is molten rock.  this has over time allowed the lighter minerals like quartz and feldspar to rise to the surface, while the heavier minerals like nickel and iron make up the earth's core.
