Many people didn't believe him at first. (Yes. 4. Another important piece of evidence in the Continental Drift theory is the fossil relevance. Lystrosaurus, on the other hand, was located in Africa, India, and Antarctica. Wegener used fossil evidence to support his continental drift hypothesis. This could be explained either by the migration of the magnetic pole itself (that is, polar wandering) or by the migration of Europe relative to a fixed pole (that is, continental drift).

Embryology, similarity, and vestigial structures. Glacial deposits, specifically till, of the same age and structure are found on many separate continents that would have been together in the continent of Pangaea. Continental drift describes one of the earliest ways geologists thought continents moved over time. This theory was met with skepticism and was largely dismissed by the scientific community for many years. However, he supported his theory by explaining the earth's geologic history. 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. As they are the same density, they break when they collide and are forced upwards instead. How rocks fossils and climate provide evidence of continental drift? Wegeners theory of continental drift states that the existing continents of the earth were once glued together forming a super landmass.

According to the modern day map, these continents are far apart. Scientists agree that continents rest on rocks called tectonic plates, which shift and move. Destruction happens when one plate moves below the other at convergent boundaries. It was hard for Wegner to back his theory as he was unable to explain how the continents moved. continents look like puzzle pieces and seem to fit together.

Because Wegener could not identify a mechanism capable of moving continents. Fossils are the stongest evidences of plate tectonics. This essay is available online and was probably used by another student. Another term for subduction is slab pull which suggests that as the denser oceanic plate is subducted at a convergent margin, they become denser than the underlying mantle and pulls the rest of the plate behind it.

The "Wallace Line". By Staff Writer Last Updated March 29, 2020 According to National Geographic, sea floor spreading and plate tectonics indicate that the continents do move or shift, which supports continental drift theory. 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. In terms of rock composition, at locations where continents match up, the kinds of rocks on the opposite sides of the continents were of the same kind. Continents are stationary and do not move.

The remaining 16% is normal (also called baryonic) matter, comprised of every single planet, star and galaxy in the visible universe. According to the latter hypothesis, Earths surface, or lithosphere, is composed of a number of large, rigid plates that float on a soft (presumably partially molten) layer of the mantle known as the asthenosphere. Alfred Wegener proposed that the continents were once united into a single supercontinent named Pangaea, meaning all earth in ancient Greek. Magnetic Reversals After molten lava emerges from a volcano, it solidifies to a rock. B. 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. 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. After Pangaea split up, Wegner believed it formed the continents of Gondwanaland and Laurasia about 200,000 years ago before continuing to split apart to form the continents we know today. The central dogma of biology. In support of the continental drift theory, it was established that South Africa, India, Australia and South America all experienced glaciations at the same time. This is a reptile that comes from the Early Permian of South Africa and South America. The Earth is broken into lithospheric plates that move due to convection currents. Some of the fossil evidence discovered on the continents includes mesosaurus, lystosaurus, cygnognathus and glossopteris. Gondwanaland makes up the southern continents of today. Edubirdie. The global inspection reveals an imbalance of areas of lands and sea and almost infinite variation of shapes which illustrates the continental and oceanic areas.
