WebAnswer and Explanation: 1. Due to the centrifugal force, which is acting on Earth at the equator but not at the poles. With increasing latitude, the radius r r of the circle on which a point on this latitude rotates becomes smaller. The angular velocity ω ω is constant, and the centrifugal force is proportional to the product of squared ... bjp rajasthan twitterWebBasically the bulge is caused by the rotation of the Earth.
