Alfred Wegener In November 1926 Wegener presented his continental drift theory at a symposium of the American Association of Petroleum Geologists in New York City, again earning rejection from everyone but the chairman. Three years later the fourth and final expanded edition of “The Origin of Continents and Oceans” appeared.

Continental Drift: Theory & Definition Continental drift was a theory that explained how continents shift position on Earth's surface. Set forth in 1912 by Alfred Wegener, a geophysicist and meteorologist, continental drift also explained why look-alike animal and plant fossils, and similar rock formations, are found on different continents.late tectonics is the widely accepted theory that Earth's crust is fractured into rigid, moving plates. In the 1950s and 1960s, scientists discovered the plate edges through magnetic surveys of the ocean floor and through the seismic listening networks built to monitor nuclear testing.

Continental drift Continental drift is the movement of the Earth's continents relative to each other, thus appearing to drift across the ocean bed. The speculation that continents might have 'drifted' was first put forward by Abraham Ortelius in 1596. second problem was that Wegener's estimate of the velocity of continental motion, 250 cm/year, was implausibly high. (The currently accepted rate for the separation of the Americas from Europe and Africa is about 2.5 cm/year). And it did not help that Wegener was not a geologist.

When Continental Drift Was Considered Pseudoscience It was a century ago this spring that a little-known German meteorologist named Alfred Wegener proposed that the continents had once been massed together in a single supercontinent and then gradually drifted apart. He was, of course, right.

Continental drift Continental drift is the movement of the Earth's continents relative to each other, thus appearing to drift across the ocean bed. The speculation that continents might have 'drifted' was first put forward by Abraham Ortelius in 1596.he British geologist Arthur Holmes championed the theory of continental drift at a time when it was deeply unfashionable. He proposed in 1931 that the Earth's mantle contained convection cells that dissipated radioactive heat and moved the crust at the surface.

Geology: Who proposed the concept of continental drift? In line with other previous and contemporaneous proposals, in 1912 the meteorologist Alfred Wegener amply described what he called continental drift, expanded in his 1915 book The Origin of Continents and Oceans and the scientific debate started that would end up fifty years later in the theory of plate tectonics.

Continental drift Antonio Snider-Pellegrini's Illustration of the closed and opened Atlantic Ocean (1858). Continental drift is the movement of the Earth's continents relative to each other, thus appearing to drift across the ocean bed.The speculation that continents might have 'drifted' was first put forward by Abraham Ortelius in 1596.he theory of continental drift was not accepted for many years. One problem was that a plausible driving force was missing. A second problem was that Wegener's estimate of the velocity of continental motion, 250 cm/year, was implausibly high.

How Did Alfred Wegener Support His Theory of Continental Drift? Quick Answer. When Alfred Wegener first made his case for continental drift, he relied on two main lines of argument: the shape of the continents and the relative positions of glacial till deposits. Evidence later accumulated from other areas of research, but the theory was not taken seriously until well after Wegener's death. Continue Reading

Alfred Wegener Continental drift theory. Alfred Wegener first thought of this idea by noticing that the different large landmasses of the Earth almost fit together like a jigsaw puzzle. The Continental shelf of the Americas fit closely to Africa and Europe, and Antarctica, Australia, India and Madagascar fitted next to the tip of Southern Africa.

Who came up with the theory of plate tectonics? Rating Newest Oldest. Best Answer: Plate tectonic theory arose out of the hypothesis of continental drift first proposed by Alfred Wegener in 1912 and expanded in his 1915 book The Origin of Continents and Oceans that said in part that all the continents once been together in a single land mass that had drifted apart.

Continental Drift: Theory & Definition But geologists soundly denounced Wegener's theory of continental drift after he published the details in a 1915 book called The Origin of Continents and Oceans.. Part of the opposition was because Wegener didn't have a good model to explain how the continents moved apart.

- The theory of plate tectonics and continental drift were proposed at the beginning of the last century by a German scientist, Alfred Wegener. Before his time it was believed that the planet's features, such as mountains, were caused by the crust shrinking as the Earth cooled after it was formed.

ART NOTES Alfred Wegener, early in the twentieth century, was the first, leading, scientific proponent of continental drift. He marshaled geometric, paleontological, paleoclimatic, and geological evidence to support continental drift; but his ideas were largely rejected in England and the United States.
