WEGNERS EVIDENCE FOR CONTINENTAL DRIFT Evidence from fossilized organisms and mountain chains can be used to reconstruct the positions of todays continents and landmasses to form the supercontinent Pangea. Wegener himself did not collect the fossils but he called attention to the idea of using these scientific doc uments stating there were fossils of species present in separate continents in order to support his claim. In the early 1960s, the emergence of the theory of plate tectonics started a revolution in the earth sciences. There are various examples of fossils found on separate continents and in no other regions. One of the strongest pieces of evidence is the jig-saw like fit between all of the continents. The Mesosaurus is known to have been a type of reptile, similar to the modern crocodile, which propelled itself through water with its long hind legs and limber tail. Tropical plants found in Arctic- tropical plants can't grow in cold climates. For example, the outward curve of the African coast matches the inward curve of . Undoubtedly, this interpretation is in complete disagreement with Darwins evolution theory. Set forth in 1912 by Alfred Wegener, a geophysicist, and meteorologist, continental drift also explained why look-alike animal and plant fossils, and related rock formations, are found on different continents. Wegener suggested that when the organisms were alive the lands were joined and the organisms were living side-by-side. They based their idea of continental drift on several lines of evidence: fit of the continents, paleoclimate indicators, truncated geologic features, and fossils. The theory of continental drift is most associated with the scientist Alfred Wegener. Wegener had many thoughts regarding what could be the driving force behind continental drift. At the base, the system has thick tillite indicating extensive and prolonged glaciation. This was developed in the early part of the 20thcentury, mostly by a single scientist, Alfred Wegener. Similar to the land dwelling Cynognathus, the Lystrosaurus would have not had the swimming capability to traverse any ocean. The third reason. What are the evidence in support of the continental drift theory? What is evidence use to prove continental drift? For example, fossils of the ancient reptile mesosaurus are only found in southern Africa and South America. According to the continental drift theory, the supercontinent Pangaea began to break up about 225-200 million years ago, eventually fragmenting into the continents as we know them today. What are six pieces of evidence for the continental drift theory? Eric Benet Greenleaf, %PDF-1.4 Earths climates have changed many times in the planets long history.

(2017, December 19). Most of the Earths geologic activity takes place at plate boundaries. Alfred Wegener's continental drift theory has five evidences which have been explained in this video. (It doesn't.) It is the sedimentary rock formed out of deposits of glaciers. 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.

Modern day representation of the Mesosaurus. Why didn't people believe Alfred Wegener? Wegener discovered that the Appalachian Mountains of the eastern United States, for instance, were geologically related to the Caledonian Mountains of Scotland. Heat coming from the interior of the earth triggers this movement to occur through convection currents inside the mantle. Falkland Island, Madagascar, Antarctica, and Australia besides India. Therefore, the continents must have been joined at least one point in time in order to maintain the Glossopteris wide range across the southern continents. Continental drift was a theory that explained how continents shift position on Earth's surface. And why did British scientists view the theory as a pleasing confirmation? Do Men Still Wear Button Holes At Weddings? These processes were the main geologic forces behind what Wegener recognized as continental drift.

Continental Drift Alfred Wegener, in the first three decades of this century, and DuToit in the 1920s and 1930s gathered evidence that the continents had moved. These rocks then drifted apart on separate continents. Wegener said the rocks had formed side-by-side and that the land had since moved apart.

Figure 3. Let's see what happens if we add the idea of Continental Drift, proposed by Alfred Wegener. What are the 3 types of continental drift? Alfred Wegener collected diverse pieces of evidence to support his theory, including geological fit and fossil evidence. He could not identify the driving force that was able to make the continents move. His hypothesis states that continents move around on Earth's surface and that they were once joined together as a single supercontinent (Figure 6.5). Are you going to support Wegener?

The students will be able to use electronic tools to explore the history of Earth s idea continental! The speculation that continents might have 'drifted' was first put forward by Abraham Ortelius in 1596. Pangaea existed about 240 million years ago. Examples include: the Appalachian Mountains of eastern North America linked with the Scottish Highlands, the familiar rock strata of the Karroo system of South Africa matched correctly with the Santa Catarina system in Brazil, and the Brazil and Ghana mountain ranges agreeing over the Atlantic Ocean. % The earliest marine fossils found along the eastern coast of South America and the western coast of Africa date from about 150 to 200 million years ago, suggesting that the Atlantic Ocean did not exist prior to that time.

But a hypothesis is rarely accepted without a mechanism to drive it. The first and earliest supercontinent to have existed is the most theoretical. The discovery of apparent polar wander renewed scientists interest in continental drift. The movement is caused by the convection currents that roll over in the upper zone of the mantle. Steve Boxall Ubs Linkedin, Although Wegeners evidence was sound, most geologists at the time rejected his hypothesis of continental drift. This indicates that these continents had to be once joined together because the extensive oceans between these land masses act as a type of barrier for fossil transfer.

While Wegener was alive, scientists did not accept continental drift was controversial at time. Geological fit evidence is the matching of large-scale geological features on different continents. Alfred Wegener proposed that the continents were once united into a single supercontinent named Pangaea, meaning all earth in ancient Greek. Arc Welding Pdf, NEWSLETTER; CONTACT US; FAQs Heavy glaciers carve grooves in the rock as they move across land. He thought the force of Earths spin was sufficient to cause continents to move, but geologists knew that rocks are too strong for this to be true. Describe sea - floor spreading 7 . Intro: Evidence for Plate Tectonics There is variety of evidence that supports the claims that plate tectonics accounts for (1) the distribution of fossils on different continents, (2) the occurrence of earthquakes, and (3) continental and ocean floor features including mountains, volcanoes, faults, and trenches. The theory of seafloor spreading states that new ocean crust is continually being formed, and that this crust is slowly carried away from its point of origin over a period of time. According to National Geographic, sea floor spreading and plate tectonics indicate that the continents do move or shift, which supports continental drift theory. As molten rock rises from the Earth, it forms new crust between the plates. Convergent boundaries: where two plates are colliding. What did Harry Hammond Hess realize in the 1950s? Theory of the Continental Drift. His first piece of evidence was that he had noticed that there was a puzzle interlocking between several continents, most notably South America and Africa, .

The earths outer shell is composed of plates that move a little bit every year. Demon Slayer Daki, Magnetite crystals are like tiny magnets that point to the north magnetic pole as they crystallize from magma. Some of the most dynamic sites of tectonic activity are seafloor spreading zones and giant rift valleys. Subduction zones occur when one or both of the tectonic plates are composed of oceanic crust.
