The observation of the alternating magnetic stripes on the seafloor was instrumental in formulating the hypothesis of seafloor spreading.
people here are stupid , really the answer is not hi
dumb question. don't want to write it all
The seafloor spreading hypothesis suggests that the primary cause of continental movement is the upwelling of magma at mid-ocean ridges, which creates new oceanic crust. The movement of this newly-formed crust pushes the existing seafloor apart, leading to the gradual separation and movement of the continents.
They proved that the seafloor was spreading.

One key piece of support that was not included in the initial support for Harry Hess's hypothesis of seafloor spreading was the mechanism of plate tectonics. This idea was developed and integrated into the theory of seafloor spreading by geologists like Robert Dietz and J. Tuzo Wilson at a later stage.
A diagram that shows how seafloor spreading works.
Gravity in the oceanic crust is responsible for seafloor spreading.
Seafloor spreading is triggered by a rift in a continental land mass.
It helped us by creating the theory of seafloor spreading which is the proof alfred needed to complete his hypothesis
