WebMar 29, 2024 · Sea floor spreading further supports the continental drift theory. As molten rock rises from the Earth, it forms new crust between the plates. When this occurs, the sea floor grows wider, pushing the two continents apart. Sea floor spreading indicates that since the continents presently move apart, previous continental drift was possible … WebSupporting Wegener’s theory of continental drift, Hess explained how the once-joined continents had separated into the seven that exist today. The continents don’t change dramatically or move independently, but are transported by the shifting tectonic plates on which they rest. The theory also explained Hess’s puzzling guyots.

As new seafloor forms and spreads apart from the mid-ocean ridge it slowly cools over time. Older seafloor is, therefore, colder than new seafloor, and older oceanic basins deeper than new oceanic basins due to isostasy. If the diameter of the earth remains relatively constant despite the production of new crust, a mechanism must exist by which crust is also destroyed.
