If the rate of seafloor spreading was faster than the rate of subduction than we would have had much more land mass on the surface on the Earth. This will cause lots of very long and very high mountain ranges in the oceans (much bigger ones that the ones that are forming now) and because of the huge amount of magma that will be pushing through they will be getting above the ocean waters and forming new land masses, and that will make the world much different from what we now it now.

In popular parlance, discussions of colonialism in Africa usually focus on the European conquests of the New Imperialism and the Scramble for Africa (1884-1914) era, followed by gradual decolonisation. The principal powers involved in the modern colonisation of Africa are Britain, France, Germany, Portugal, and Italy.
The answer is seafloor spreading. It is a progression that happens at mid-ocean ridges which are the divergent boundaries, where new oceanic crust is made through volcanic activity and then slowly moves away from the ridge. This helps clarify the continental drift theory in the plate tectonics theory.
