*\nGetting to the Core\nDon't believe Jules Verne. The center of the Earth is not a nice place to visit, unless you like hanging out in a blast furnace. The outer core of the Earth, about two-thirds of the way to the center, is molten iron. Deeper yet, at the inner core, the pressure is so great -- 3.5 million times surface pressure -- that iron solidifies, even though the temperature is believed to exceed 11,000 degrees Fahrenheit, hotter than the surface of the sun.\n\nDespite rapid advances in high-pressure laboratory techniques, it's not yet possible to duplicate these conditions experimentally, and until Stixrude and Cohen's work, scientists could at best make educated guesses about iron's atom-to-atom architecture -- its crystal structure -- at the extremes that prevail in the inner core. Using a quantum-based approach called density-functional theory, Stixrude and Cohen set out to do better than an educated guess. With recent improvements in numerical techniques, density-functional theory had predicted iron's properties at low pressure with high accuracy, leading the researchers to believe that with supercomputing they could, in effect, reach 3,000 miles down into the inner core and pull out what they needed.\n\n\nCRYSTAL AT THE CENTER OF THE EARTH: Anisotropy of Earth's Inner Core  [New Window] \nThere's a giant crystal buried deep within the Earth, at the very center, ...

That's an interesting question.  Very little would happen that you would notice at the edge.  The center of gravity for a sphere (like the Earth) is the geometric center of the shpere and at any point on the sphere, a straight line could pass from the center of the sphere, through your feet and through your head when you are standing erect.  Because the curvature of the Earth is hard to detect where you stand, you sense that you are standing perpendicular to the ground.\n\nThe center of gravity of an Earth-sized cube would also be the geometric center of the cube.  However a cube has six sides and the very center of each side would be the only six places on the cube where you could stand erect perpendicular to the surface.  At any other point, especially as you approach an edge or corner, a straight line should pass through the center of the cube, your feet and your head, but you would be standing erect at an angle to the surface.  Right on the edge, a straight line could pass throught the center of the cube, the edge, your feet and your head as you stand erect relative to gravity.  As you step over an edge, the slope of the angle would begin to tilt the opposite way as you leave the edge toward the center of the next side.\n\nThere is an interesting point that when the British performed the original land surveys of India near Mt. Everest, the results were in error because they neglected to account for the gravitational pull of the mountain that affected perpendicularity of their plumb bob.  This effect might also create an abberation near the edges and corners of your cube.  At any rate, you would stand erect parallel to any plumb bob that you held.

There is no populated geographic center of the Earth.  The center of the Earth is many miles underground and obviously not occupied.  \nIf you mean, which country is at the center of the surface of the Earth, there's no answer to that either, because the Earth is a sphere, and there are no edges from which to measure a center.

Drilling into the crust can not possibly affect the internal temp of the earth. We can NOT possibly dig deeper than that. easy. Next question.

Anywhere you are,is the center of the surface of the Earth.More technically,If you want to be in the actual center,you would have to go to the core.

Depends on how you define "middle." The center of the earth is the core, which is just short of 4000 miles down from the equator. If you're talking about the definition of "middle" in terms of the surface, then the only natural center is the Equator, which divides the southern and northern hemispheres. Since the Earth's rotation is uniform (at least in terms of unaided human scale observations), any attempt to define longitudinal hemispheres winds up being wholely artificial. The prime meridian (0 degrees longitude) is simply defined as the line that runs between the north and south poles that passes through the center of a particular telescope located at the Royal Observatory in Greenwich, England. There are historical reasons why that line was chosen, but at the end of the day, it's as good as any other one that you might choose. It's just that nowadays, it's what everyone agrees upon. So the middle of the western hemisphere is at 90 degrees west, 0 degrees latitude, which is very near the Galapagos Islands in the Pacific ocean and the middle of the Eastern hemisphere is in the middle of the Indian ocean, southeast of Sri Lanka.\n\nThe middles of the northern and southern hemispheres are the respective poles.

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

Earth's core is thought to be made of molten nickel-iron. The core is about 2100 miles in radius, with a temperature of approximately 13,000 degrees Fahrenheit.

Well, I appreciate the fact that you include a waiver for many of the things that would make this task impossible, that helps a lot ;)\n\nIf some explorer were able to dig a hole straight through the center of the earth, the digger would slowly find the apparent effects of gravity decreasing as he or she approaches the center.  On the surface of the earth we feel a good, solid 1G because we have this huge mass effectively "underneath" us but our explorer would slowly be working his way down until only a portion of said mass is "underneath" them... the rest is above them and around them.  By the time they reach the center, they would essentially have a nearly equal amount of mass in all directions, all pulling with pretty much the same amount of force.  Yup, they'd feel like they were floating and would have trouble discerning any "up" or "down" by then.  When they start digging the rest of the way through, they are no longer digging "down", and the further from the center of the earth it will feel more like digging up.  By the time they break through to the other side, they're back to a nice steady 1G.\n\nI hope this helps you, and I hope you don't need the equasions.  We're talking about some serious calculus here and I'm not sure I'm up to that right now ;)\n\nDuckie

Let me ask you, what would it be like of you were at the end of the Earth? Would it be like a cliff that you could jump off? That is silly because the Earth is round. It has a finite surface area but no edge. The edge is the surface you are standing on. Every place on Earth is the edge. It is believed that in a similar way the 3D universe is curved in the 4th dimension, so that it has a finite volume but no edge. Or you could say you are at the edge all the time but don't know it since you cannot perceive the 4th dimension.

The Core.  There was nothing even remotely correct about it... except that maybe people usually live on the outside of the earth, and the earth is made up of rock.\n\nWhen that movie came out, all the geologists at my school got together and watched it and either sat around with mouths agape or laughing out loud.

Technically you'd start digging up when you reached the centre of the core and entered the 'the half' whether you'd immediatly feel the shift is questionable... I think as you got right close to the centre of the earth your sense of up and down would weaken, so it wouldn't be until you'd got some way away that you'd feel like you were going up...and yes once you'd got up you would fall back down due to gravity. Think of the gravity as those like the force on those playground things you can spin in circle and the centrifugual force can be used to mkde you spin faster or slower as you hold yourself close in or furtehr out...the further out you are the more you feel the froce...the closer in the less obvious it is.\n\nEdit: 8928 the core is solid... your talking about the mantle in which even rocks are molten.

Earth is an oblate spheroid, resembling a sphere flattened at the poles.\n\nThe volume of an oblate spheroid is\n\n    V = 4/3 X 3.14 X a^2 X b\n\nwhere π is the mathematical constant pi, and a and b are the equatorial and polar radii.\n\nSubstituting a = 6,378,135 m and b = 6,356,750 m\n\nThe Huge EarthThe mean radius of the earth is approximately 6.4 million meters (exact = 6.37 x 106 m). Its volume is then:\n\n(4/3) x 3.14 x 64000003 m3\n\nThis comes to 1,097,509,500,000,000,000,000 cubic meters.

I'll be back after i look it up.\n\nOk, here's what I found below.  Also, what I found reminds me of journey to the center of the earth.  So I think that about covers it.

I think,to a good approximation, at the centre you would not feel an appreciable gravitational field from the mass of the earth. \n\nIt's a nice result in physics that if you're on the interior of a spherical shell of mass then you feel no gravitational force. You can think of the centre as being surrounded by layer after layer of spherical shells of radius ~0 up to the radius of the earth.\n\nIf you do the calculation, once you start going interior to the earth the gravitational attraction varies linearly with distance from the centre-going from 9.81m/s^2 at the surface to 0 m/s^2 at the centre.\n\nOutrageous!

A molten core of super heated metal (believed to be Iron and Nickel) is spinning at the center of the earth faster than the exterior of the earth is rotating.\n\nCharged Particles create a magnetic field when they move.
