- 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.his slideshow explains Wegener's theory. Earth around 200 million years ago, at the time of Pangaea. Wegener’s evidence for continental drift was that: 1  the same types of fossilised animals and plants are found in South America and Africa.

- Continental drift was a theory proposed in 1912 by Alfred Wegener which postulated the movement of continents.This theory is a part of the concept of plate tectonics. Continents have been drifting for hundreds of millions of years.ontinental drift was a theory proposed in 1912 by Alfred Wegener which postulated the movement of continents.

Why Was Alfred Wegener's Continental Drift Theory Rejected? Other scientists at the time had observed the similarities in fossils in South America and Africa. However, many embraced the idea that these were the result of a land bridge between the two continents. In addition, Wegener's explanation for continental drift was weak.

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 During his lifetime he was primarily known for his achievements in meteorology and as a pioneer of polar research, but today he is most remembered as the originator of the theory of continental drift by hypothesizing in 1912 that the continents are slowly drifting around the Earth (German: Kontinentalverschiebung).

- 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.

- In his work, Wegener presented a large amount of observational evidence in support of continental drift, but the mechanism remained elusive, partly because Wegener's estimate of the velocity of continental motion, 250 cm/year, was high.egener's main interest was meteorology, and he wanted to join the Denmark-Greenland expedition scheduled for mid-1912. He presented his Continental Drift hypothesis on January 6, 1912. He analyzed either side of the Atlantic Ocean for rock type, geological structures and fossils.

- Although Wegener's continental drift theory was discarded, it did introduce the idea of moving continents to geoscience. And decades later, scientists would confirm some of Wegener's ideas, such as the past existence of a supercontinent joining all the world's landmasses as one.

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.

- The study of Paleomagnetism is what finally proved Alfred Wegner's theory of continental drift. Paleomagnetism in short discovered identical polarities on either side of the …mid-Atlantic ridge. As Earth's magnetic poles switch, more polarities are added to both sides of the ridge.

- The first to use the term continental drift was Alfred Wegener. He proposed that the cause of continental drift was the continents being been pulled apart by the centrifugal force of the Earth's rotation, but this was considered unrealistic by other scientists.

Continental Drift: Theory & Definition Evidence for continental drift. A map of the continents inspired Wegener's quest to explain Earth's geologic history. Trained as a meteorologist, he was intrigued by the interlocking fit of Africa's and South America's shorelines.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.

- In the 1960's, however, geologists discovered that the ocean floors had been spreading, thus influencing the shapes and sizes of the continents. This new theory, called plate tectonics, provided a mechanism that made sense in physical terms to account for Wegener's idea of continental drift.lfred Wegener, who was educated to be a meteorologist and an Arctic climatologist, insisted that his theory was correct because of the evidence he saw. To support his ideas about continental drift, Wegener pointed to the similarities in the fossils of the southern continents.

And decades later, scientists would confirm some of Wegener's ideas, such as the past existence of a supercontinent joining all the world's landmasses as one.art of the opposition was because Wegener didn't have a good model to explain how the continents moved apart. Though most of Wegener's observations about fossils and rocks were correct, he was outlandishly wrong on a couple of key points.

High School Earth Science/Continental Drift Wegener used fossil evidence to support his continental drift hypothesis. The fossils of these organisms are found on lands that are now far apart. Wegener suggested that when the organisms were alive, the lands were joined and the organisms were living side-by-side.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.
