High Quality Content by WIKIPEDIA articles! The evolution of tectonophysics is closely linked to the history of the continental drift and plate tectonics hypotheses. The continental drift hypothesis had many flaws and scarce data. The fixist, the contracting Earth and the expanding Earth concepts had many flaws as well. Wegener had data for assuming that the relative positions of the continents change over time. It was a mistake to state the continents "plowed" through the sea. He was an outsider with a doctorate in astronomy attacking a established theory between geophysicists. The geophysicists were right to state that the Earth is solid, and the mantle is elastic (for seismic waves) and inhomogeneous, and the ocean floor would not allow the movement of the continents. But excluding one alternative, substantiates the opposite alternative: passive continents and an active seafloor spreading and subduction, with accretion belts on the edges of the continents.
