Is the Earth round? Or is the Earth flat as a pancake?
The Earth is certainly not flat. The Earth is almost spherical, like a ball. However, it is slightly fatter around the equator, so its circumference around the equator is longer than the circumference that runs north-south. This means that the Earth’s true shape is approximated by a shape called an oblate spheroid. The oblate spheroid is as accurate as most people need when referring to the Earth’s shape. However, the geoid is a more accurate means of referring to the Earth’s shape. I’ll let you read about it here if you choose: http://en.wikipedia.org/wiki/Geoid The Earth rotates around the geographical North Pole, which is not the same as the magnetic North Pole.
