Alfred wegener proposed the theory of continental drift - the idea that the earth's continents move over hundreds of millions of years of geologic time - long before the idea was commonly accepted. Earlier theories (eg by alfred wegener and alexander du toit) of continental drift postulated that continents ploughed through the sea the idea that the seafloor itself moves (and also carries the continents with it) as it expands from a central axis was proposed by harry hess from princeton university in the 1960s . In 1912 alfred wegener his theory of continental drift, wegener came across a paleontological paper suggesting that a land bridge had once connected africa with .

Alfred wegener & harry hess continental drift wegener studied the atmosphere as a meteorologist the theory was that they later sunk into the ocean wegener .
Harry hammond hess, a professor of geology at princeton university, was very influential in setting the stage for the emerging plate-tectonics theory in the early 1960s he believed in many of the observations wegener used in defending his theory of continental drift, but he had very different views about large-scale movements of the earth. Hess made a major contribution to the continental drift theory, which viewed continental and oceanic positions as the result of the break up of a single supercontinent (a theory first proposed by alfred wegener in 1912) suggesting a mechanism by which continents could move away from each other without tearing up a rigid seafloor, hess . Continental drift and plate tectonics alfred wegener : these symmetric stripes supported a theory by hess on sea floor spreading, which we now know exists at .

Wegener’s critics correctly pointed out, however, that the continents could not simply “plow” though the ocean floor as wegener had vaguely theorized it was hess who determined how oceanic mountain ranges, called mid-ocean ridges, are fundamental to the tectonic movement that results in the drift of continents.
