Plate Tectonics: The Story of a Model (1-B)

Scientific Issue:
Alfred WEGENER was the first to clearly introduce the idea of the horizontal mobility of continents on the Earth's surface (1912). Initially rejected, his work was later taken up to eventually lead to the theory of plate tectonics.
What arguments allowed WEGENER to bring about the idea of horizontal mobility of the lithosphere?
What additional data later led to the acceptance of this idea within the framework of plate tectonics?
