wegener's theory Alfred Wegener (1880 - 1930). Alfred Wegener proposed the theory of continental drift at the beginning of the 20th century. His idea was that the Earth's continents were once joined together, but gradually moved apart over millions of years.efore Wegener developed his theory, it was thought that mountains formed because the Earth was cooling down, and in doing so contracted. This was believed to form wrinkles, or mountains, in the Earth's crust. If the idea was correct, however, mountains would be spread evenly over the Earth's surface.

- • Alfred Wegener published a book proposing that the continents had been connected. • He called this supercontinent Pangea. • The separation of the continents became known as continental drift. ARE THE CONTINENTS MOVING?

wegener's theory Alfred Wegener proposed the theory of continental drift at the beginning of the 20th century. His idea was that the Earth's continents were once joined together, but gradually … moved apart over millions of years. The idea was rejected at first as he was a Meteorologist and not regarded as a proper scientist.

Alfred Wegenerâs Continental Drift Hypothesis From 1912, Wegener publicly advocated the theory of “continental drift”, arguing that all the continents were once joined together in a single landmass and have drifted apart. He supposed the cause might be the centrifugal force of the Earth’s rotation (“Polflucht”) or the astronomical precession.

- The idea that the continents were once one super-continent and subsequently moved apart is the basis of the theory of continental drift. Continental drift was first proposed … as a scientific hypothesis with evidences by Alfred Wegener early in the twentieth century.erman scientist Alfred Wegener (1880-1930) first proposed the theory of continental drift in 1912, but it was not widely accepted until the 1950s.

High School Earth Science/Continental Drift The evidence for continental drift included the fit of the continents; the distribution of ancient fossils, rocks, and mountain ranges; and the locations of ancient climatic zones. Although the evidence was extremely strong, scientists could not think of a mechanism that could drive solid continents to move around on the solid earth and most rejected the idea.

Continental Drift: Theory & Definition Plate 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.

wegener's theory Before Wegener developed his theory, it was thought mountains formed because the Earth was cooling down, and in doing so contracted. This was believed to form wrinkles, or mountains, in the Earth's crust.If the idea was correct, however, mountains would be spread evenly over the Earth's surface.his is the current position of the continents. Wegener's evidence for continental drift was: 1  The same types of fossilised animals and plants are found in South America and Africa. 2  The shape of the east coast of South America fits the west coast of Africa, like pieces in a jigsaw puzzle.

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.et 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.

** Continental Drift and the Theory of Plate Tectonics (Part of a series of essays identifying and explaining theories essential to understanding modern scientific thought.) Continental drift, in the context of the modern theory of plate tectonics, is explained by the movement of lithospheric plates over the asthenosphere (the molten, ductile, upper portion of the Earth's mantle).

- Continental Drift-Evidence. The evidence which gave rise to the theory of continental drift -- more correctly called plate tectonics -- includes the following: ► The coasts of the continents surrounding the Atlantic ocean could, if the continents were moved closer, fit together like a jigsaw puzzle.

High School Earth Science/Continental Drift He named the supercontinent Pangaea, meaning entire earth in ancient Greek. Wegener further suggested that Pangaea broke up long ago and that the continents then moved to their current positions. He called his hypothesis continental drift.lthough Wegener’s evidence was sound, most geologists at the time rejected his hypothesis of continental drift. These scientists argued that there was no way to explain how solid continents could plow through solid oceanic crust. At the time, scientists did not understand how solid material could move.

What is Continental Drift Theory? Ad. Continental drift theory also gained in popularity because of the theory of plate tectonics. Briefly, plate tectonics suggests that the ocean floor began to spread and that the continents existed on “plates” that moved in response to the changing ocean floor.
