Continental drift (Site not responding. Last check: 2007-11-04) |
 | | New rock is created by volcanism at mid-ocean ridges and returned to the Earth's mantle at ocean trenches. |
 | | Remarkably, in the 1928 AAPG volume, G. Molengraaf of the Delft Institute (now University) of Technology proposed a recognizable form of seafloor spreading in order to account for the opening of the Atlantic_Ocean as well as the East Africa Rift. |
 | | Confirmation of this hypothesis would have to wait for further evidence. |
