Description
On January 6, 1912, German geophysicist and meteorologist Alfred Wegener presented his groundbreaking theory of continental drift at a meeting of the Geological Association in Frankfurt am Main, Germany. This...
show moreWegener had been fascinated by the apparent fit of the coastlines of South America and Africa, and he spent years gathering evidence to support his idea that the continents were once joined together in a single landmass he called "Pangaea." He argued that around 200 million years ago, this supercontinent began to break apart, and the individual continents slowly drifted to their current positions.
To support his theory, Wegener pointed to the similarity of rock formations and fossil records on opposite sides of the Atlantic Ocean. He also noted the presence of glacial deposits in regions that are now far from polar ice caps, suggesting that the continents must have been in different positions in the past.
Despite the compelling evidence, Wegener's theory was met with skepticism and even ridicule from many of his contemporaries. Critics argued that there was no known mechanism powerful enough to move continents across the Earth's surface, and they dismissed his ideas as speculative and unscientific.
It wasn't until the 1960s, long after Wegener's death, that his theory gained widespread acceptance. The discovery of seafloor spreading and the development of plate tectonics provided the missing mechanism to explain continental drift, and Wegener's once-controversial ideas became the foundation of modern geology.
Today, we recognize Alfred Wegener as a visionary scientist whose bold thinking and tireless pursuit of evidence helped to revolutionize our understanding of the Earth's dynamic history. His legacy serves as an inspiration to all those who dare to challenge conventional wisdom and push the boundaries of scientific knowledge.
