30 sie 2024 · Wegener also compiled evidence by comparing similar rocks, mountains, fossils, and glacial formations across oceans. For example, the fossils of the primitive aquatic reptile Mesosaurus were found on the separate coastlines of Africa and South America.
Geological “fit” evidence is the matching of large-scale geological features on different continents. It has been noted that the coastlines of South America and West Africa seem to match up, however more particularly the terrains of separate continents conform as well.
24 sie 2024 · Wegener’s first evidence was that some continents’ coastlines fit together like pieces of a jigsaw puzzle. People noticed the similarities in the coastlines of South America and Africa on the first world maps, and some suggested the continents had been ripped apart.
19 paź 2023 · This map displays an early "supercontinent," Gondwana, which eventually moved to form the continents we know today. Fossils of similar organisms across widely disparate continents encouraged the revolutionary theory of continental drift. Map by USGS. Photograph.
One piece of evidence Wegener provided was paleoclimatic indicators that linked South America and Africa (Plate Tectonics: Continental Drift). He noted that glacial, tropical rain forests, and desert deposits were aligned when the continents were placed together (Plate Tectonics: Continental Drift).
Looking at a map of the world, it appears that the eastern edge of South America and the western edge of Africa could fit together like interlocking puzzle pieces. Scientists have long noticed the similarity between the two coastlines, but it was not until the 20th century that evidence could support a theory that the continents were once ...
15 lis 2023 · In the face of so much evidence in support of continental drift, how could scientists reject the idea? Look at a world map. Besides the coast of west Africa and eastern South America, what are some other regions of the world that look as they could be closely fit together?
