![]() Occur in India, Madagascar and Africa led some to consider a contiguous landmass ‘Lemuria’ linking these three landmasses.Īll this provided evidences of this theory. When identical species of plants and animals adapted to living on land or in fresh water are found on either side of the marine barriers, a problem arises regarding accounting for such distribution. The gold bearing veins are in Brazil and it is obvious that the gold deposits of the Ghana are derived from the Brazil plateau when the two continents lay side by side. The occurrence of rich placer deposits of gold in the Ghana coast and the absolute absence of source rock in the region is an amazing fact. Alfred Wegener in Greenland in the winter of 1912-13. Overall resemblance of the Gondawana-type sediments clearly demonstrates that these landmasses The theory revolutionized the Earth sciences, explaining a diverse range of geological phenomena and their implications in other studies such as paleogeography and paleobiology. Succession are found in Africa, Falkland Island, Madagascar, Antarctica and Australia. At the base, the system has thick tillite indicating extensive and The Gondawana system of sediments from India is known to have its counterparts in six different landmasses of the Southern Hemisphere. The earliest marine deposits along the coastline of South America and Africa are of the Jurassic age.ĭeposits of glaciers. The belt of ancient rocks of 2,000 million years from Brazil coast matches Rocks of Same Age Across the Oceans were found. The shorelines of Africa and South America facing each other have a remarkable and unmistakable match. Gondwanaland continued to break into various smaller continents that exist today.Ī variety of evidence was offered in support of the continental drift are mentioned below: Pangaea first broke into two large continental masses as Laurasia and Gondwanaland forming the He argued that, around 200 million years ago, the super continent, Pangaea, began to split. The mega-ocean was called PANTHALASSA, meaning all water. The super continent was named PANGAEA, which meant all earth. This was regarding the distribution of the oceans and the continents.įormed a single continental mass and mega ocean surrounded the same. Meteorologist who put forth a comprehensive argument in the form of “the continental drift theory” in 1912. 1596 Abraham Ortelius noted that the coastlines of the Americas, Africa, and Europe indicate the continents were once together. History of science, it was Abraham Ortelius, a Dutch map maker, who first proposed such a possibility as early as 1596. No wonder, many scientists thought of this similarity and considered the possibility of the two Americas, Europe and Africa, to be once joined together. ![]() Of the coastlines on either side of the ocean. The theory of continental drift provoked outrage, despite the idea having been in circulation for centuries. Observing the shape of the coastline of the Atlantic Ocean.
