Wegener’s evidence for continental drift was that:

Wegener obtained his doctorate in planetary astronomy in 1905 but soon becameinterested in meteorology; during his lifetime, he participated in severalmeteorologic expeditions to Greenland. Tenacious by nature, Wegener spentmuch of his adult life vigorously defending his theory of which was severely attacked from the start and never gained acceptancein his lifetime. Despite overwhelming criticism from most leading geologists,who regarded him as a mere meteorologist and outsider meddling in theirfield, Wegener did not back down but worked even harder to strengthen histheory.

Wegener had launched a revolution—and he knew it. Just two weeks earlier, he had written his future father-in-law, eminent climatologist Wladimir Koppen, "if it turns out that sense and meaning are now becoming, evident in the whole history of the Earth's development, why should we hesitate to toss the old views overboard?"

alfred wegeners theory rejected

Despite general rejection, Wegener's compelling concept continued to attract a few advocates over the next several decades. Then, beginning in the mid-1950s, a series of confirming discoveries in paleomagnetism and oceanography finally convinced most scientists that continents do indeed move. Moreover, as Wegener had predicted, the movement is part of a grandscale process that causes mountain-building, earthquakes, volcanic eruptions, sea-level fluctuations, and apparent polar wandering as it rearranges Earth's geography.

"Doesn't the east coast of South America fit exactly against the west coast of Africa, as if they had once been joined?" wrote Wegener to his future wife in December 1910. "This is an idea I'll have to pursue."

The following fall Wegener came across scientific papers promoting the prevailing theory that Africa and South America had once been connected by a continent-size land bridge that had since sunk into the sea. They cited as evidence fossils of identical animals that had lived in both areas simultaneously hundreds of millions of years ago.

Wegener used evidence of climate change to support his hypothesis

Wegener suggested that mountains were formed when the edge of a drifting continent collided with another, causing it to crumple and fold. For example, the Himalayas were formed when India came into contact with Asia.

BBC - GCSE Bitesize: Wegener’s theory

Alfred Wegener is most famous for his work on continental drift, but it's not generally known that he was an atmospheric physicist whose specialty was polar meteorology, that he did work in glaciology on three different expeditions to Greenland, and that his theory of Continental drift, first developed in 1912 was progressively transformed from a geological into a climate theory. Working together with his father-in-law, Wladimir Köppen, a famous climatologist deeply interested in the origin of ice ages, Wegener produced three versions of his theory in 1920, 1922, and 1924 that show increasing emphasis through time on the causes of ice ages in both the northern and southern hemisphere. His work on continents was deeply influenced by his Greenland experience with icebergs and ice floes, pressure ridges, and the metamorphism of snow into ice. I will talk about this material and mention some of the work done by Harlan Bretz in Greenland after his work on the "Ice Age Flood," and talk about some similarities in the theories of these two scientists, and the way their work was treated by their respective scientific establishments.

Continental drift is the movement of the Earth's continents relative to each other, ..

why was wegener hypothesis rejected by most scientists …

Alfred Wegener brought together several lines of evidence to support his theory of continental drift. One is quite simple -- that the continents look like they could "fit" together, much like puzzle pieces that have drifted apart. Then, he noticed that when you put the continental puzzle pieces back together, other things started to fit. For example, the rock layers that form the Appalachian mountains of the eastern U.S. matched quite well with those in Scotland. Fossils found on the east coast of Brazil match quite nicely with fossils found in western South Africa. Also, he noticed that a lot of the fossilized life found in the rock record didn't fit in the climates they were found in. For example, rocks in Alaska contain fossil palm tree leaves, though there have not been palm trees at that latitude for a very long time! Thus, he concluded that the continents must 'drift' around the Earth, occasionally colliding with one another. Though his ideas were not popular at the time, they were the foundation of one of the greatest scientific revolutions in history!
