how was alfred wegeners theory proven
alfred wegener his year proposed hypothesis
Wegener had launched a revolutionand 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.
Why was wegener's hypothesis rejected by most scientists …
"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."
Wegeners hypothesis by Edna Winkler - issuu
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.
