Is The Earth Like A Perfect Ball?
The earth is not a perfect sphere, but is slightly flat at the two poles, and is widest at the equator. The ‘diameter’ of the earth, that is the length of an imaginary line drawn through the center of the earth from one end to the other, is about 7,926 miles at the equator, but only about 7,900 miles from pole to pole. Thus the earth is more than 26 miles wider at the equator than it is at the poles.
The shape of the earth which is not a perfect sphere is called `Oblate spheroid’ by scientists.
Also there are four ‘corners’ where the earth’s surface bulges out slightly. These places are Ireland, and the oceans near Peru, South Africa and New Guinea.
