I Don't Know My Right From Left Cadence, So to conclude, there are at least 6 different pieces of evidence that support the theory of continental drift. Older rocks that are the same age and are located on the same continent point to the same location, but that location is not the current north magnetic pole. Wegener suggested that perhaps the rotation of the Earth caused the continents to shift towards and apart from each other. Rift valleys are sites where a continental landmass is ripping itself apart. Found inside Page 278Discuss four pieces of evidence for the idea of continental drift 6. Holmes thought this could be like a conveyor belt. Alfred Wegener, in the first three decades of this century, and DuToit in the 1920s and 1930s gathered evidence that the continents had moved. The first truly detailed and comprehensive theory of continental drift was proposed in 1912 by Alfred Wegener, a German meteorologist.Bringing together a large mass of geologic and paleontological data, Wegener postulated that throughout most of geologic time there was only one continent, which he called Pangea.Late in the Triassic Period (which lasted from approximately 251 million to 199.6 Wegener proposed that the organisms had lived side by side, but that the lands had moved apart after they were dead and fossilized. 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 speculation that continents might have 'drifted' was first put forward by Abraham Ortelius in 1596. Wegener used fossil evidence to support his continental drift hypothesis. He also matched mountain ranges together. Sea floor spreading indicates that since the continents presently move apart, previous continental drift was possible and probable as well. The earth's outer shell is composed of plates that move a little bit every year. Way the continents had remained fixed and the continents then moved to their positions! Puzzling new evidence came in the 1950s from studies on the Earths magnetic history (figure4). 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 audio, illustrations, photos, and videos are credited beneath the media asset, except for promotional images, which generally link to another page that contains the media credit. Alfred Wegener suggested that continental drift occurred as continents cut through the ocean floor, in the same way as this icebreaker plows through sea ice. Alfred Wegener proposed that the continents were once united into a single supercontinent named Pangaea, meaning all earth in ancient Greek. Continental drift describes one of the earliest ways geologists thought continents moved over time. Of course, possible explanations are brought to attention. What evidence did you consider in determining which continental boundaries should be joined? As molten rock rises from the Earth, it forms new crust between the plates. They named the phenomenon of the magnetic pole that seemed to move but actually did not apparent polar wander. The North American and Eurasian tectonic plates, for example, are separated by the Mid-Atlantic Ridge. Convergent boundaries: where two plates are colliding.

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. 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. Plates interact at three types of plate boundaries: divergent, convergent and transform. Scientists agree that continents rest on rocks called tectonic plates, which shift and move. The presence of these fossils suggests Svalbard once had a tropical climate. The main reason that Wegeners hypothesis was not accepted was because he suggested no mechanism for moving the continents.

Continental drift describes one of the earliest ways geologists thought continents moved over time. 6 pieces of evidence for continental drift 2021. 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. These fossils were of tropical plants, which are adapted to a much warmer, more humid environment. Fossil evidence for Pangaea includes the presence of similar and identical species on continents that are now great distances apart. One indication of this possibility is the appearance of the western African and eastern South American coasts, which look like two interlocking jigsaw puzzle pieces. The technical storage or access that is used exclusively for statistical purposes. Continental drift was a theory that explained how continents shift position on Earth's surface.

Continental drift is the hypothesis that the Earth's continents have moved over geologic time relative to each other, thus appearing to have "drifted" across the ocean bed. See also how are global winds related to surface ocean currents. See also how was society organized. By contrast oceanic crust is composed of basaltic rocks which are much denser and heavier. Four fossil examples include: the Mesosaurus, Cynognathus, Lystrosaurus, and Glossopteris. Heat coming from the interior of the earth triggers this movement to occur through convection currents inside the mantle. The now extinct Cynognathus, which translates to dog jaw, was a mammal- like reptile. For example, the outward curve of the African coast matches the inward curve of . Confirm sea - floor evidence is the matching of large-scale geological features on continents. 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. Which two pieces of fossil evidence supports the idea of continental drift? He used fossil evidence, such as that of tropical plants found on the Arctic island of Spitzbergen. The direction is known as the fields magnetic polarity. View this answer. The Appalachians of the eastern United States and Canada, for example, are just like mountain ranges in eastern Greenland, Ireland, Great Britain, and Norway (figure 2). What are two pieces of evidence for seafloor spreading? 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. Idea at the time spent on task: 13 what are six pieces of a freshwater reptile known as driving. Rifting began as magma welled up through the weakness in the crust creating a volcanic rift zone. . Although all models of early Earths plate tectonics are very theoretical scientists can generally agree that there have been a total of seven supercontinents. Continental drift was a theory that explained how continents shift position on Earths surface. Modern day representation of the Mesosaurus.
