The observation of the alternating magnetic stripes on the seafloor was instrumental in formulating the hypothesis of seafloor spreading.
One observation that was not instrumental in formulating the hypothesis of sea floor spreading is the distribution of terrestrial fossils across continents. While these fossils provided evidence for continental drift, they did not directly relate to the mechanisms of sea floor spreading, which is primarily supported by observations such as the age of oceanic crust, magnetic stripe patterns on the sea floor, and the presence of mid-ocean ridges.
One day while scientists were exploring the sea floor, they discovered sea-floor spreading, thus proving Wegener's hypothesis to be correct.
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.
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.
No, Alfred Wegener did not use sea-floor spreading, ridge push, or slab pull to develop his hypothesis of continental drift. Wegener proposed his theory in 1912, long before these concepts were formulated in the mid-20th century as part of the theory of plate tectonics. Instead, Wegener based his hypothesis on evidence such as the fit of continental coastlines, fossil distribution, and geological similarities across continents. The mechanisms of sea-floor spreading and plate tectonics were developed later to explain the movement of continents.

Because of sea floor spreading
Granitic strips in the ocean floor ... Novanet
evidence supporting the idea of sea-floor spreading.

people here are stupid , really the answer is not hi
dumb question. don't want to write it all
