According to Wegener, the following two forces are responsible for the flow of continents:
1. Gravity or flotation force: This force causes the drifting of land towards the 1 equator. As: the flow of India and Australia.
2. Tidal force: Due to this force, the drift of land turns towards the west like the flow of North – South America. This flow is due to the combined tidal forces of the Sun and the Moon. In it, the landmass is believed to be drawn by the sun and the moon towards the west.
