Wegener proposed that the movement causing the continents to drift was driven by two forces: the pole-fleeing force and the tidal force. The pole-fleeing force is related to the Earth's rotation, which causes a bulge at the equator because the Earth isn&rsquo;t a perfect sphere. The second force, the tidal force, is caused by the attraction of the Moon and the Sun, which create tides in the oceans. Wegener believed that over millions of years, these forces would move the continents. However, most scientists at the time disagreed, believing these forces were not strong enough to cause the continents to drift.
