Theory of Plate Tectonics was established by Alfred Wegener. 3. 2. Fossils of creatures and plants discovered on different continents helped to him push his case that the continents were once locked together before breaking up and drifting away. What are the four pieces of evidence for continental drift quizlet? Magnetic Reversals After molten lava emerges from a volcano, it solidifies to a rock. 6014 , CY. Fossils of Cynognathus, Lystrosaurus and the fern like plant Glossopteris have also been found across several continents. Finding fossils of the Mesosaurus on the southern hemispheres of both continents is a further indication that the two continents were once together and later drifted apart. The continents were once joined in a super-continent and have moved over time. 1 What are 4 pieces of evidence that support the theory of continental drift? This theory was met with skepticism and was largely dismissed by the scientific community for many years. One piece of evidence is the complementary shapes of earths coastlines. The causes of continental drift are perfectly explained by the plate tectonic theory. Rocks of Same Age Across the Oceans: The belt of ancient rocks of 2,000 million years from Brazil coast matches with those from western Africa. Government programs to settle the land But about 200 million years ago, the land started to drift apart and broke into two pieces. Which statement best supports the theory of continental drift quizlet? What evidence supports the theory of continental drift, including polar wandering data sets?

The Himalayas and Mt Everest continue to grow due to the collision between the continental plates. This suggested that these continents were once together and drifted away over time. On the basis of all these factors, it may be assumed that the Americas were joined with Europe and Africa until approximately 190 million years ago, when a rift split them apart along what is now the crest of the Mid-Atlantic Ridge.

Mesosaurus - small fresh water reptile. Genetics. Continental drift theory was given by Alfred Wegener in 1915. If you look at the current map after the continents drifted away, you find that North America and Africa are far away from each other separated by the Atlantic Ocean. What evidence did Wegner use to support his theory of continental drift? The continents we see today are fragments of that supercontinent. What are six pieces of evidence for the continental drift theory? These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. Find out everything you need to know about it here. The following piece of evidence represents matching geologic provinces in Africa and South America. 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. What are the 5 evidences of continental drift? Embryos of four different species. Mountains created by colliding continents. It has affected the global climate, the worlds geographical positions and the evolution of animals. Abundant evidence supports the major contentions of the seafloor-spreading theory. Answer (1 of 3): Continental drift is not a theory, it is a measured fact. Specific interpretations in Darwins theories of evolution pose challenges to modes of proceeding within feminist critique. Over the course of millions of year ago, this gradual movement caused the once combined supercontinent to separate into 7 continents you witness in the present day. The theoretical model builds on the concept of continental drift developed during the first few decades of the 20th century. continents look like puzzle pieces and seem to fit together. When he was tasked with proving how these continents moved to different places, he couldnt. This indicates that the continents were once fixed together and drifted apart over time. Plant Fossils- all these regions were once connected and had similar climates. Wegener's accumulated evidence could be most logically explained by continental drift. It is thought that all the continents were once joined together in one super-continent, named Pangaea. . Which type of evidence was NOT used by Alfred Wegener to support his continental drift hypothesis? 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. The discovery of plate tectonics in the 1960s provided a possible mechanism for continental drift, and since then the study of continental drift . 4. 2023 EduBirdie.com. 2. How is plate tectonics supported by the apparent fit of the continental coastline? Some 50 years later, Antonio Snider-Pellegrini, a French scientist, argued that the presence of identical fossil plants in both North American and European coal deposits could be explained if the two continents had formerly been connected, a relationship otherwise difficult to account for. Fossil evidence for Pangaea includes the presence of similar and identical species on continents that are now great distances apart. Aside from the congruency of continental shelf margins across the Atlantic, modern proponents of continental drift have amassed impressive geologic evidence to support their views.

As a result of movement of the supercontinent, Pangaea split into two super landmasses namely Laurasia and Gondwanaland. 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. Wegener supported his theory by demonstrating the biological and geological similarities between continents. What evidence exists to support the existence of Pangea 3 points? What is the Best Piece of Evidence for Plate Tectonics? Impact craters have been found both on dry land and on the ocean floor.
