Hess's hypothesis of seafloor spreading provided a mechanism for continental drift, explaining how and why continents moved apart. It also incorporated evidence from oceanic crust age, magnetic striping, and sea-floor topography, filling the gaps in Wegener's original theory. This new explanation laid the foundation for the development of the theory of plate tectonics.

What was the fatal weakness in wegeners theory?
One of the fatal weaknesses in Wegener's theory of continental drift was the lack of a plausible mechanism to explain how continents could move through the solid rock of Earth's mantle. Additionally, Wegener was unable to adequately explain what forces could be responsible for moving the continents.

Why is cell theory a theory and not a hypothesis?
Cell theory is a theory given by R. Virchow in 1855 .It is a theory not a hypothesis because it has been proved thus it can not be considered hypothetical , that's why is not called hypothesis.
What does a hypothesis become after it is tested and proven?
A hypothesis, or group of hypotheses, that is accepted as consistently valid is a theory. Either a hypothesis or a theory can be ultimately disproven. One definition of a theory is an accepted hypothesis.
How is a hypothesis and a theory alike?
Both a hypothesis and a theory offer an explanation of some observed phenomenon. The difference is that a hypothesis must have confirmation to become a theory.
