WebTheory and Evidence of Seafloor Spreading. Seafloor spreading is a geologic process where there is a gradual addition of new oceanic crust in the ocean floor through a volcanic activity while moving the older rocks away from the mid-oceanic ridge. The mid-ocean ridge is where the seafloor spreading occurs, in which tectonic plates —large ... WebNov 19, 2024 · Scientific evidence for seafloor spreading supports this theory. For example, the age of the seafloor closest to the ridge is the youngest, and it progressively gets older as the distance from the ...
