What evidence supports the continental drift theory? In the 1900's, Alfred Wegener presented an argument supporting continental drift. Theory of Plate Tectonics was established by Alfred Wegener. 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. Alfred Wegener, in the first three decades of this century, and DuToit in the 1920s and 1930s gathered evidence that the continents had moved.

Mesosaurus are fossils originating from aquatic freshwater reptiles. Mountain ranges and the location of ancient climatic zones. none of the above. What supports Wegeners theory of plate tectonics? Gondwanaland contained all the masses in the southern hemisphere such as Africa, Antarctica, South America and Australia. 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. Set forth in 1912 by Alfred Wegener a geophysicist and meteorologist continental drift also explained why look-alike animal and plant fossils and similar rock formations are found on different continents. Another evidence that supports the theory of continental drift is Paeomagnetism. Theory of the Continental Drift. The following are the evidence of continental drift theory: The Matching of Continents: The shorelines of Africa and South America facing each other have a remarkable and unmistakable match. On top of that, Lystrosaurus is situated in Antarctica, India, and Africa according to the modern map. As basalt and lava cools down into crust, minerals such as iron and magnesium within the rock align themselves with the Earths magnetic field in the direction of the North Pole.

Dark matter is an incredibly elusive force which is necessary for many modern theories that describe the movement of galaxies and effectively all of the major elements of the universe. Sea floor spreading indicates that since the continents presently move apart, previous continental drift was possible and probable as well. Gondwanaland makes up the southern continents of today. After Wegener died on an arctic expedition in 1930, only a handful of loyal supporters continued to promote his ideas. Fossils and Mountain ranges were his evidences. However, these different paths are reconciled by joining the continents in the manner proposed by Wegener. Where the plates collide they form fold mountains e.g. Continental drift is the suggestion that over long periods of geological time, the continents of the Earth have moved apart from each other and had once formed almost one single land mass known as Pangaea. Despite being dismissed at first, the theory gained steam in the 1950s and 1960s as new data began to support the idea of continental drift.

What are the 5 evidences of continental drift? Wegner also noticed that rocks and mountain ranges across continents looked similar and were similar ages, the belt of ancient rocks of 2,000 million years ago from the Brazilian coast matches with those from western Africa he also noticed that there were similar geological sequences in eastern Canada and Scotland. They based their idea of continental drift on several lines of evidence: fit of the continents, paleoclimate indicators, truncated geologic features, and fossils. Source: www.slideserve.com.
