Book excerpt: Excerpt from The American Journal of Science, Vol. 2 If the earth were not rotating and its materials were homogeneous with respect to depth, the actual surface of the earth would be a true sphere. The earth is rotating and, therefore, the combination of the gravitational force and the centrifugal force would make this ideal earth have a surface which would be a spheroid of revolution.
