The Earth is not completely round

The Earth is not completely round

The shape of the earth is not completely round shape, much like an orange , that is both the North and the South Pole are slightly pressed and the equatorial region slightly inflated . The reason for this particular size is that the daily motion of the Earth around its axis and the resultant centrifugal force.When the world was created, its temperature was very high. So the world was formed by melting fused and gaseous substances. Centrifugal force has its highest value in equatorial region, so in ancient period of creation the melting fused and gaseous substances have more tendency to move away from the axis in the equatorial region. On the other hand, the value of centrifugal force in the polar axle is zero, so the particles have not any tendency to move away from the axis. However from the beginning, particles in the Earth are interconnected force was very high. As a result the substances of the equatorial region, when some distance away from the axis under the influence of centrifugal force, the substances of the polar region came under the influence of the cohesion  force. After this,with the decreasing of temperature of earth the substances became bundled. Then the earth took this form of shape.
