Lystrosaurus provided which type of evidence supporting continental drift? The map below (based on data in the Paleobiology Database) shows locations where these fossils have been found. Apparent polar wander is another line of evidence for drifting continents. 3. Background and Objectives: The maples have radiated from East Asia into two Continental drift has impacted the universe in many ways. Why do you think they did not accept continental drift? There is only one logical explanation. As shown in figure, an air conditioner operating at steady state maintains a dwelling at 70F70^{\circ} \mathrm{F}70F on a day when the outside temperature is 90F90^{\circ} \mathrm{F}90F. Description showing the fossil locations of the Mesosaurus, Cynognathus, Lystrosaurus, and Glossopteris spread across different continents. When the rock cools and solidifies, this alignment is frozen into place, creating a permanent paleomagnetic record that includes magnetic inclination related to global latitude, and declination related to magnetic north. In 1896, Henry Cabot Lodge warned, Your email address will not be published. They wanted to know which direction magnetite crystals pointed. The little magnets point to where the North Pole was when the lava cooled. Similar to the land dwelling Cynognathus, the Lystrosaurus would have not had the swimming capability to traverse any ocean. How does the Mesosaurus fossil evidence support the continental drift theory? Continental drift was a revolutionary theory explaining that continents shift position on Earths surface. The distribution of these reptiles in different continents proves that these separate land masses were once together before splitting. According to the Lystrosaurus and Cygnognathus body anatomy, they are not designed for swimming. 5.5: Continental Drift is shared under a CC BY 4.0 license and was authored, remixed, and/or curated by LibreTexts. Anywhere lavas have cooled, these magnetite crystals point to the magnetic poles. Rocks deposited by glaciers that existed 250 million years ago are found in similar-aged rocks of southern Africa, South Africa, India, and Australia. These reptiles lived in freshwater bodies such as lakes and rivers. Ch 13 and 14 questions 7 .docx - Retention Questions continental drift - National Geographic Society How does paleomagnetism serve as evidence for continental drift? Your email address will not be published. shows us glaciers once covered a large portion of the land in the southern hemisphere. However, the location they point to is not the current north magnetic pole. in. Which of the following What Wegener did differently was synthesizing a large amount of data in one place. n@.#|?W h +{j.xy( [:@3{LgZao}4KW{.ettF!0G B^qxIl k#1FS7MRY4@3{#j9R]D%w3_:jM& The two paths merge into one if the continents are allowed to drift. The seafloor drilling system led to the evidence that supports the seafloor-spreading hypothesis. As it turns out, current scientific knowledge reveals convection is the major force in driving plate movements. There was once widespread agreement about phlogiston (a nonexistent element said to be a crucial part of combustion), eugenics, the impossibility of continental drift, the idea that genes were made of protein (not DNA) and stomach ulcers were caused by stress, and so forthall of which proved false. Similarities Between Kannemeyeria And Labyrinthodont What mountains in Northwestern Europe match up with the Appalachian Mountains in Eastern North America?
