You do realize that it is still hard for the scientist to determine the actual shape of earth?

I never claimed it being flat and there is a big difference between cone shaped and egg shaped..

however earth is shaped I wouldn't be able to answer that more of what I have been hearing from some scientists who could be very wrong and the same goes for you..

**What is the shape of the Earth?** Posted on

2 March 2009 by

John To first approximation, out planet is a sphere. But how accurate is that approximation? What’s a better approximation? How good is that? This post will answer these questions and some related questions.

**How well does a sphere describe the Earth’s shape?** The Earth’s polar diameter is about 43 kilometers shorter than its equatorial diameter, a difference of about 0.3%.This is due to the equatorial bulge caused by the Earth’s rotation.

**What’s a more accurate description of the Earth’s shape?** An oblate spheroid.

**What is an oblate spheroid?** It’s the shape you get by spinning an ellipse around it’s minor axis. That says if you were to take a cross-section of the Earth containing the polar axis, the shape you get would be an ellipse. The polar axis would be the minor axis and the equatorial axis would be the major axis. But if you were to take a cross-section through the equator, or any plane parallel to the equator, you’d get a circle.

**What is a prolate spheroid?** A

*prolate* spheroid is what you get by spinning an ellipse around its

*major* axis.

**What is an ellipsoid?** An ellipsoid satisfies the following equation.

A sphere is an ellipsoid with a = b = c. An oblate spheroid is an ellipsoid with a = b > c. A prolate spheroid is an ellipsoid with a = b < c. A scalene ellipsoid is an ellipsoid for which a, b, and c are all distinct.

**How good is the oblate spheroid model?** The error in approximating the Earth’s shape as an oblate spheroid is less than 100 meters, two orders of magnitude better than the spherical model.

**How are other planets shaped?** The other planets in our solar system are also oblate spheroids with Saturn being the most oblate: the polar diameter of Saturn is about 10% shorter than its equatorial diameter.
