Studies of Earth's magnetic field and oceanographic research showed that present-day ocean basins are not as old as continents but instead, are geologically young features that resulted from the breakup of Pangaea. This supports the theory of continental drift, which suggests that the continents were once joined together in a supercontinent called Pangaea and have since moved apart.
