Wegener gave continent drift theory but his argument about the drifting force of continents was not so strong to convince. Pole fleeing force and tidal force can not drift such large continents.
Arthur Holmes gave convention current theory in 1930 and try to explain the forces that lead to drifting the large landmasses.

- Convention current is generated in the mantle portion. Disintegration Radioactive elements in the mantle create a thermal gradient which causes current to flow in a circular manner in the earth mantle.
- Earth has many convention currents.
- Convention currents are mainly the driving forces of continents.
