British geophysicist who was ahead of his time in suggesting that there were convection currents in Earth's interior. His model proposed that these currents rise under the oceans and fall under the continents. He also proposed that a large supercontinent was split apart when the Moon was torn from Earth, leaving the Pacific Ocean as a scar, and that the remaining pieces of continental crust floated apart.
