The Groeber’s vision on “The Expanding Earth” is presented based on his pioneering work published in the late 50’s. This essay provides an explanation of various mechanisms and phenomena that would act on planet Earth, such as its expansion over time and the development of convective currents explaining the variation of paleogeography of the continents and oceans over time. The theory began to gain adherents among geologists and it is still partially valid, but does not adequately explain the mobility of the continents. To justify this hypothesis Groeber explains how in an expanding Earth dominated by extensional efforts, compressive efforts could uplift mountain ranges, produced by convective currents and the Benioff zone. He discusses aspects of both theoretical geology and those obtained through field evidence. This new contribution highlights significant elements related to a theoretical change in geology at a time when the paradigm of fixed continents and the geosynclinal theory was being abandoned, trying to explain the mobility of the continents through the expanding Earth. Although we know today that it was a failed act, it is interesting to emphasize the robustness of Groeber’s reasoning in order to explain that mobility. © 2017, Asociacion Geologica Argentina.
