The shortest distance between two points on earth is a parabolla called the great circle distance.

Dudes, the eqeator or prime meridian do NOT go THROUGH the center of the earth AT ALL!\n\nThe answer is Axis, duh.

No, u will stuck in center. As it is familiar that the earth is more or less spherical in shape. So the "point of gravity" lies at the centre of the earth (the core we say).\n\nSo when u jump into that whole (which u digged) u will go inside, due to gravity. Once u reach the mid point (core), the gravity becomes zero. But with the old force, u will move further, making negative gravity, (that is gravity in opposite direction), from the opp direction, u will come back to the centre. \nThis will repeat until the gravity becomes zero, after that u will stuk up at the core.

Because it is the truth. Geocentric theory had placed the Earth at the certer of the Universe. We now know this to be incorrect. The heliocetric theory holds that the earth revolves around the sun and the sun is not the center of the universe. Chaos theory states that no place in the universe is special and that for us to presume that the earth is the center of the universe is False logic.

One is incorrect and the other is correct.  The heliocentric model (or Copernican model) places the sun as the center of the solar system, with the planets revolving around it, which is correct.  \n\nThe geocentric model place the earth as the center of the solar system, with the planets and the sun rotating around it.  This is incorrect.  \n\nIn the 17th Century, the astronomer Galileo was branded a heretic and excommunicated from the Church for "daring" to challenge the Vatican's misguided belief (derived from a literal reading of the Bible) that the geocentric model was correct.  Science ultimately vindicated Galileo as correct, and the Church only issued a formal retraction of the excommunication of Galileo in this century.

Just supose that the universe end in some point, that has a boundary. What would be outside? Nothing? And... what is between Mars and the Earth? Also nothing. The universe is... "the nothing", and never ends. Anyway, and suposing that you forget the relativity theory and you want to know where is the star/planet/thing that is farest from the "centre", you can say that the radius of the universe is less or equal to the speed of light times the age of the univers.

*\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, ...

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!

depends.....at the equator, from the surface to sea level, it is 6,378.135 km. from the centre to the north or south pole, at sea level, it is 6,356.750 km. remember, both of those are to sea level, and they differ because the world is not a perfect sphere.

The correct option is 'rotation of the earth'. When earth revolves, some part of it is directly facing the sun, and the other part is not. That explains the presence of day in one part of the world, and night in the other.

The earth is round and its gravitational pull draws us to its center.  Upside-down is really just pointing away from the core...from anywhere.

There are a few main parts to the earth. The earth is like a tootsie pop: a hard crunchy exterior, and it is soft inside. They are in roughly concentric spheres. The main layers of the earth are called the crust, the mantle and the core. \n\nThe outside shell of the earth is called the crust. The crust is about 5-60 kilometers thick and forms about 1% of the volume of the earth. We live on the crust. \n\nUnder the crust is a very large part of the earth called the mantle. The mantle is about 84% of the volume of the earth. The mantle is about 2800 kilometers thick.\n\nInside the mantle, is the soft middle of the earth, called the core. The core is roughly a round ball, and is about 15% of the volume of the earth, and has a radius of about 3400 Km. \n\nOf course, one can get much more detailed, but this is enough to give you a start, so you can understand what you read on the internet.

The inner core of the Earth is composed of solid metal (almost a pure alloy of iron and nickel) and extends from the center of the Earth to a radius of about 1220 kilometers (about 758 miles).  \n\nThe outer core is a 2260 km-thick (~1404 mile) shell of molten iron-nickel that surrounds the solid inner core.\n\nFor comparison, the Earth's average radius (it's not a perfect sphere) is 6371 km, so the inner core extends 1220/6371*100 = ~19% of the whole radius of the Earth.

The radius of the Earth is approximately 6,350km.\n\nFirst, convert your latitude and longitude values from degrees into radians. This is done by dividing by 360 and then multiplying by 2pi. \n\nIf the latitude was south, make it negative. \nIf the longitude was west, make it negative. \n\nSupposing you flatten out the Earth's surface for your X-Y plane:\n\nXcoordinate (in km) = longitude(in radians) * 6350\nYcoordinate (in km) = latitude(in radians) * 6350

Your teacher.\n\nThe sun is the center of our solar system (thus the terminology), and all of the planets circle around the sun.\n\nJust to clarify on one point...The sun is not the center of the universe.  It is the center of our solar system.  There are thousands of solar systems in our universe, and our sun is not at the center of these.
