Lets explore. Geological fit evidence is the matching of large-scale geological features on different continents. The observations that Lemurs occur in India, Madagascar, and Africa led some to consider a contiguous landmass Lemuria linking these three landmasses. 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.

The rock as they move across land hypothesis as early as 1596 glaciers! He argued that around 200 million years ago the super continent Pangaea began to split. One explanation is the species could have migrated via a land bridge or swam to the other continents. Africa, for example, will eventually split along the Great Rift Valley system. Jimmy Butler Wingspan, The students will be able to identify the evidence for continental drift and locate them on a map Comment Avoir Midas En Ombre, The earths outer shell is composed of plates that move a little bit every year. 6 in. Most of the coal fields in the world are located in these countries along with good quality coal fields are found in Africa and South America. These rocks then drifted apart on separate continents. What are the 5 evidences of continental drift? What are 3 fossils that support the idea of continental drift? The four pieces of evidence for the continental drift include continents fitting together like a puzzle scattering ancient fossils rocks mountain ranges and the old climatic zones' locations. Continental drift describes the motion of Earth's continents only; plate tectonics describes the motion of the crust beneath Earth's oceans as well. Hess discovered that the oceans were shallower in the middle and identified the presence of Mid Ocean Ridges raised above the surrounding generally flat sea floor (abyssal plain) by as much as 1.5 km. What Are The 4 Pieces Of Evidence For Continental Drift? The scientists looked again at the three possible explanations. As molten rock rises from the Earth, it forms new crust between the plates.

Continental drift was a theory that explained how continents shift position on Earth's surface. Similar to the land dwelling Cynognathus, the Lystrosaurus would have not had the swimming capability to traverse any ocean. An additional resolution is that the species could have merely evolved separately on the other continents. Continental Drift: Theory & Definition.

He found large-scale geographic features that matched, like the Appalachian Mountains in the United States and the Scottish Highlands, as well as rock strata in South Africa that matched those in Brazil. His polar experiences, Wegener suggested that Pangaea broke up long ago and that the continents fixed. These include Pannotia, which formed about 600 million years ago, and Rodinia, which existed more than a billion years ago. However, convectional currents are the general thought for the motion. What evidence supports plate tectonics quizlet? He could not identify the driving force that was able to make the continents move. Moreover, swimming as a possibility is foolish due to the lack of formidable swimming capabilities to travel across such an extensive body of water like the Atlantic. Not consenting or withdrawing consent, may adversely affect certain features and functions. 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. The processes of seafloor spreading, rift valley formation, and subduction (where heavier tectonic plates sink beneath lighter ones) were not well-established until the 1960s. Description showing the fossil locations of the Mesosaurus, Cynognathus, Lystrosaurus, and Glossopteris spread across different continents. Scientists still do not appear to understand sufficientlythat all earth sciences must contribute evidence toward unveiling the state of our planet in earlier times, and that the truth of the matter can only be reached by combing all this evidence. Tuzo said that Earth's crust, or lithosphere, was divided into large, rigid pieces called plates. The theory of continental drift is most associated with the scientist Alfred Wegener. He suggested that Pangaea broke up long ago and that the continents then moved to their current positions. There are various examples of fossils found on separate continents and in no other regions. Convection currents within the asthenosphere are a primary driving force behind the motion of the continents. 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. Answer the question(s) below to see how well you understand the topics covered in the previous section. 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 causes of continental drift are perfectly explained by the plate tectonic theory. While Wegener was alive, scientists did not accept continental drift was controversial at time. Describe sea - floor spreading 7. The presence of mesosaurus suggests a single habitat with many lakes and rivers. 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. Wegener used fossil evidence to support his continental drift hypothesis. Sea floor spreading indicates that since the continents presently move apart, previous continental drift was possible and probable as well. Found insideNext Generation Science Standards identifies the science all K-12 students should know. They named the phenomenon of the magnetic pole that seemed to move but actually did not apparent polar wander. The main difference between plate tectonics and continental drift is that plate tectonics describes the features and movement of Earth's surface in the present and in the past whereas continental drift describes the drifting of Earth's continents on the ocean bed.

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. Wegeners idea was nearly forgotten until technological advances presented even more evidence that the continents moved and gave scientists the tools to develop a mechanism for Wegeners drifting continents. Grooves and rock deposits left by ancient glaciers are found today on different continents very close to the equator. Wegener used fossil evidence to support his continental drift hypothesis.
