Abstract

The earth is defined as being round but in fact the true shape of the earth is described by the term Geoid which means the Polar regions are flat while the Equatorial region bulges out. The spinning of the earth develops a centrifugal force which forces the mass to spread out while simultaneously another counterforce, the centripetal force comes into play. Both the forces work in a coordinated manner. The centrifugal force throws out the mass, thereby creating a space around the central part of the earth. Consequently, the mass in Polar regions tend to fill up this space or vacuum. This causes the Polar regions to be flat. This is because the rpm (rotational speed per minute) of spinning is slower at the Polar regions when compared to the Equatorial region.
