7 Οκτ 2014 · Hess’s Theory In 1962, as a result of oceanographic research conducted in the 1950's, Harry Hammond Hess proposed the theory of seafloor spreading to account for continental movement. He suggested that continents do not move across oceanic crust, but rather that the continents and oceanic crust move together.
Harry Hess published 'The History of Ocean Basins' in 1962, outlining a theory of how tectonic plates can move which was later called 'sea floor spreading'. He identified the presence of mid ocean ridges, and that ocean trenches are where ocean floor is destroyed and recycled.
This process is called plate tectonics, and it transformed the thinking of geologists. One of them, Harry Hess, was an instrumental figure in figuring out how plate tectonics worked. Hess possessed two valuable skills: careful attention to detail and the ability to form sweeping hypotheses.
20 Μαΐ 2024 · 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.
Harry Hess (1960) proposed an idea suggesting a process of sea-floor spreading Seafloor Spreading- sea floor spreads apart along both sides of a mid-ocean ridge as new crust is created. Ocean floors move like a conveyer belt, carrying continents along with them.
THE CONTINENTAL DRIFT CONTROVERSY. Volume III: Introduction of Seafloor Spreading. Resolution of the sixty-year debate over continental drift, culminating in the triumph of plate tectonics, changed the very fabric of Earth science.
20 Μαΐ 2024 · This question particularly intrigued Harry H. Hess, a Princeton University geologist and a Naval Reserve Rear Admiral, and Robert S. Dietz, a scientist with the U.S. Coast and Geodetic Survey who first coined the term seafloor spreading.
