What are the evidences of continental drift? |
Answer» I am Abhinab Sahu dhruv .<br>Evidence that supports the theory\tThe Matching of Continents (Jig-Saw-Fit):\xa0The shorelines of Africa and South America facing each other match remarkably.\tRocks of Same Age Across the Oceans:\xa0radiometric dating methods have correlated the rock formation in different continents.\tTillite:\xa0The glacial tillite found in Gondwana system of sediments has its resemblance to six different landmasses of the Southern Hemisphere. Counterparts of this succession are found in Africa, Falkland Island, Madagascar, Antarctica and Australia besides India.\tPlacer Deposits:\xa0The placer deposits of gold in the Ghana coast do not have source rock in the region. The gold deposits of Ghana have been derived from the Brazil plateau when the two continents lay side by side\tDistribution of Fossils:\xa0identical species of plants and animals adapted to living on land or in freshwater are found on either side of the marine barriers. For example remains of Mesosaurus, a freshwater crocodile-like reptile that lived during the early Permian (between 286 and 258 million years ago), are found solely in Southern Africa and Eastern South America.<br>The evidence for continental drift included the fit of the continents; the distribution of ancient fossils, rocks, and mountain ranges; and the locations of ancient climatic zones. | |
