Plate Tectonics Theory of Continental Drift The continental drift hypothesis was developed in the early part of the 20th century, mostly by Alfred Wegener. Fossils - certain fossils preserved in rocks of the same age but from different continents. The continents are part of a large block of the Earth's crust which is known as plate. Embryos of four different species. Cygnognathus is Fossil from another species of reptile. 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. What Evidence Supports The Theory Of Continental Drift? Continental drift was a theory that explained how continents shift position on Earths surface. 1 What evidence supports the continental drift theory? Temperature and pressure both increase with depth. Continental plates are 30km-70km thick whereas the thinner oceanic plates are only 5km-10km thick. Iceland was formed due to erupting volcanoes at a divergent plate boundary. What pieces of evidence were used to support plate tectonics? The rest of the earth was covered with one huge ocean. The first truly detailed and comprehensive theory of continental drift was proposed in 1912 by Alfred Wegener, a German meteorologist. 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. According to National Geographic, sea floor spreading and plate tectonics indicate that the continents do move or shift, which supports continental drift theory. Another fossil that supports the hypothesis of continental drift is Glossopteris (glahs AHP tur us). 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. Which piece of evidence would provide the strongest support for the hypothesis that Earths continents were once joined? Wegener used fossil evidence to support his continental drift hypothesis. Continents fit like Puzzle Pieces. Which does not support the theory of continental drift? 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. Fossil records are strong evidence that the continents do drift. This perfect aligning of mountain ranges indicated that the continents were once together. Fossils. 4 What is evidence use to prove continental drift? With the development of modern science and physical proof that the Earths continents are moving, the evidence is overwhelming and it is hard to deny Wegners theory that the continents once formed a single land mass and drifted apart over a long period of geological time. tobi brown girlfriend; ancient map of sarkoris pathfinder; reno sparks nv obituaries; como sacar una culebra de su escondite Fossils of similar types of plants and animals in rocks of a similar age have been found on the shores of different continents, suggesting that the continents were once joined. However, would you believe if someone told you that these broken land masses were once connected to each other as one huge supercontinent? Geological fit evidence is the matching of large-scale geological features on different continents. (askinglot.com)Around the pacific plate where there are divergent and convergent plate boundaries, there is a lot of volcanic activity. 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.

Wegener specifically used rock composition and mountain ranges to provide evidence of continental drift. Corrections? An example of a convergent plate boundary is the Pacific Plate and the Eurasian plate. The Mesosaurs would not have been able to swim across the ocean due to the fact they are freshwater creatures (and the vast distance between continents), so the mesosaurs at some point must have been able to walk across the continents.

Apart from fossil evidence, Wegener used climatic clues to substantiate his facts. A. Ex. 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.

Moreover, the earliest marine deposits along the Atlantic coastlines of either South America or Africa are Jurassic in age (approximately 199.6 million to 145.5 million years old), which suggests that the ocean did not exist before that time. He discovered glacier groves in continents that were not cold enough to support snow formation in the present day. Indications of widespread glaciation from 380 to 250 million years ago are evident in Antarctica, southern South America, southern Africa, India, and Australia. 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.

For millions of years, all the land of Earth was joined together in a supercontinent, which is known as Pangaea. 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.

Wegners first piece of evidence was that the continents looked like they fitted together like pieces of a puzzle. Which type of evidence was NOT used by Alfred Wegener to support his continental drift hypothesis? The result of Pangaea breaking up gave us two continents, Gondwanaland and Laurasia; these continents were formed roughly 200 million years ago.
