Web1 okt. 2024 · 1. Introduction. Plate tectonics is the central unifying theory for geology and geophysics. The original definition of plate tectonics [] has recently been modified to include a description of the driving force as ‘A theory of global tectonics powered by subduction in which the lithosphere is divided into a mosaic of plates, which move on … WebA Meteorologist, a Geologist, and the Theory of Plate Tectonics. Alfred Wegener produced evidence in 1912 that the continents are in motion, but because he could not explain what forces could move them, geologists rejected his ideas. Almost 50 years later Harry Hess confirmed Wegener’s ideas by using the evidence of seafloor spreading to ...
