In addition, South America and Africa looked like they could fit together like puzzle pieces. Ferromagnetic minerals such as magnetite acquire a permanent magnetization when they crystallize as constituents of igneous rock. Continental plates are slightly less dense (2.6-2.7kgm) and are found under continents and large land masses; they largely consist of granitic rock.

Finding identical or similar fossils in areas separated by vast distances were some of the first clues that scientists used to reconstruct past plate movement. The general response to Wegener's hypothesis, however, was disbelief. The continents shapes fit well together and some continents have the same fossils. So, technically, the creature would not have traveled through the ocean to get to the next continent. What evidence exists to support the existence of Pangea 3 points? Copy the question and answer. These reptiles lived in freshwater bodies such as lakes and rivers. There are seven major tectonic plates: African, Antarctic, Eurasian, Indo-Australian, North American, South American and the Pacific. By the late 1960s, several American investigators, among them Jack E. Oliver and Bryan L. Isacks, had integrated this notion of seafloor spreading with that of drifting continents and formulated the basis of plate tectonic theory. Almost all plate movement occurs in boundaries which lie between different plates. Analytical cookies are used to understand how visitors interact with the website. Wegener also provided evidence of continental drift by looking at the physical shape of continental coastlines. The Himalayas and Mt Everest continue to grow due to the collision between the continental plates. Since these match up points consisted of the same kind of rock further proves that the continents were once together before breaking away and drifting. Late in the Triassic Period (which lasted from approximately 251 million to 199.6 million years ago), Pangea fragmented, and the parts began to move away from one another. Some of the evidence supporting the continental drift of the tectonic plates include the presence of similar animals and plant fossils on the shores of various continents, which suggest that they were once joined.
