For example, fossils of Mesosaurus, a freshwater reptile, have been found both in Brazil and western Africa. To support his theory, Wegener pointed to matching rock formations and similar fossils in Brazil and West Africa. He knew that plant and animal fossils as well as rock layers matched up in South America and Africa. Another important piece of evidence in the Continental Drift theory is the fossil relevance.

While every effort has been made to follow citation style rules, there may be some discrepancies. Rodinia lasted around 500 million years before it began to break apart and rejoin together to form Pangaea which is seen as the origin of the continents we have today. Dark Matter earned its name because it does not interact at all with the Electromagnetic Force. As magma rises it forces the crust to rise at the ridge.

Which two pieces of fossil evidence supports the idea of continental drift? So, his theory is proved by the fact that the freshwater reptiles could not swim across the ocean waters, hence, their distribution on every continent. As the plates pulled apart from each other millions of years ago it caused earthquakes which led to magma rising from the mantle and erupting through the crust forming the Mid Atlantic Ridge as it solidified, this is called sea floor spreading as it is an example of two oceanic plates pulling away from each other.

This perfect aligning of mountain ranges indicated that the continents were once together. During the early 1960s, the American geophysicist Harry H. Hess proposed that new oceanic crust is continually generated by igneous activity at the crests of oceanic ridgessubmarine mountains that follow a sinuous course of about 65,000 km (40,000 miles) along the bottom of the major ocean basins. This was based on the evidence of fossils that he gathered. Theory of the Continental Drift.

What evidence exists to support the existence of Pangea 3 points? At convergent plates, oceanic and continental plates collide. Several types of evidence supported Hess's theory of sea-floor spreading: eruptions of molten material, magnetic stripes in the rock of the ocean floor, and the ages of the rocks themselves. Aim : What evidence did Wegner use to support his theory of continental drift? Wegeners theory of continental drift states that the existing continents of the earth were once glued together forming a super landmass. The continents shapes fit well together and some continents have the same fossils. 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. Sedimentary rocks examination showed a change in climates, and the only possible explanations are continental drift or movement of the poles. The Theory of Continental Drift was proposed by Alfred Wegener in 1912.

Impact craters have been found both on dry land and on the ocean floor. What is the Best Piece of Evidence for Plate Tectonics? Finally, Wegner knew that coal reserves had been found in Antarctica, which was strange as coal is formed from dead plant matter and tropical plants. Similar rocks found on different continents. You also have the option to opt-out of these cookies. The present continents appear to fit together as pieces of a larger landmass. Fossils of Mesosoaurs (freshwater aquatic reptiles) have been found on the continents of Africa and South America along with fossils of plant life providing more evidence that the continents were once joined and moved apart over time. 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.

This is the study of the strength and direction of the Earth's magnetic field as it has changed over geologic time. He supported his theory with geological evidence. On the other hand, tectonic movement destroys crust during interaction of the plates. Rock Correlation. Sea floor spreading indicates that since the continents presently move apart, previous continental drift was possible and probable as well. The fossils of these organisms are found on lands that are now far apart. What evidence did Wegener not support his hypothesis of continental drift? Glossopteris was Fossil from fern. How does General Mejia refer to the annexation of Texas? Some of the fossil evidence discovered on the continents includes mesosaurus, lystosaurus, cygnognathus and glossopteris. In addition South America and Africa looked like they could fit together like puzzle pieces. In 1908 Frank B. Taylor of the United States invoked the notion of continental collision to explain the formation of some of the worlds mountain ranges. Fossils of the Mesosaurus, an ancient freshwater reptile found in the southern parts of South America and Africa, also indicate that the two continents could have once been one solid continent that drifted apart, since the reptile could not have swum across the ocean. Bringing together a large mass of geologic and paleontological data, Wegener postulated that throughout most of geologic time there was only one continent, which he called Pangea.

The distribution of these reptiles in different continents proves that these separate land masses were once together before splitting. Where the plates collide they form fold mountains e.g. South America and Africa contain fossils of animals found only on those two continents, with corresponding geographic ranges. Another evidence that supports the theory of continental drift is Paeomagnetism. The discovery of fossils on different continents indicated that the continents were once together before they drifted away. 2 What are the 6 pieces of evidence for the theory of continental drift? A graphic of Gondwana. 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. Background on the Ground Alfred Wegener was the developer of a new theory of the earth's surface called continental drift, and he was an adept investigator, but he passed away in 1930 with his. This means it does not absorb, emit or reflect visible light, gamma rays, ultra-violet rays etc. It does not store any personal data. It has affected the global climate, the worlds geographical positions and the evolution of animals. However, the crust is never destroyed when plates move past one another horizontally at transform boundaries. 2 What are some of the major pieces of evidence for the theory of plate tectonics? It will explore the theory of continental drift by Alfred Wagener and the more advanced and developed theory of plate tectonics and how it has affected the volcanic hotspots and also provides several predictions for the future of Australias volcanos.
