Question

The plate tectonics theory was refined from an earlier theory. Briefly describe the earlier theory?​

Answer 1

His book The Origin of Continents and Oceans, published in 1915, is widely accepted as the beginning of modern plate tectonics, even if the theory was only widely accepted in a refined version in the 1960s. The main idea that Wegener and others had was that modern continents formed a single landmass in the past.
