Timeline of the development of tectonophysics (before 1954) scheduled for mid 1912. So he hurried up to present his Continental Drift hypothesis. Mainly Charles Lyell, Harold Jeffreys, James D. Dana, Charles Schuchert, Chester Longwell, and the conflict with the Axis powers slowed down the acceptance of continental drifting . Timeline of the development of tectonophysics (before 1954) The evolution of tectonophysics is closely linked to the history of the continental drift and plate tectonics hypotheses. The continental drift/ Airy-Heiskanen isostasy hypothesis had many flaws and scarce data. The fixist/ Pratt-Hayford isostasy, the contracting Earth and the expanding Earth concepts had many flaws as well. The idea of continents
Continental Divide of the Americas such as the International Hydrographic Organization add a sixth: Canada's Northwest Passage basin. Using just the five, there are four secondary continental divides and three secondary triple points, the two mentioned previously and a third near Hibbing, Minnesota, where the Northern Divide intersects the Saint Lawrence Seaway divide. Since there is no true consensus on what a continental divide is, there is no real agreement on where the secondary triple points are located. However, the main Continental Divide described in this article is a far more distinctive geological feature than the others and its two main triple points are much
