Continental drift was a theory that explained how continents shift position on Earth's surface. Set forth in 1912 by Alfred Wegener, a geophysicist and meteorologist, continental drift also explained why look-alike animal and plant fossils, and similar rock formations, are found on different continents. Dec 31, 2019 · The relationships between species inferred from biogeography, the fossil record, and the shapes and structures of animals today now have their most impressive confirmation from the recently developed field of genetics. If we never find another fossil or vestigial trait, genetic evidence puts common ancestry beyond reasonable doubt. See full list on phschool.com It was later suggested that perhaps they were once joined and over time, evidence was found to support this idea. For example, coal deposits and other geologic formations match up on opposite sides, as do fossils. Using this evidence, Alfred Wegener, a German geophysicist, proposed the hypothesis of continental drift. A fossil is “a remnant, impression, or trace of an organism of past geologic ages that has been preserved in the earth’s crust.” (Merriam Webster). In the example at right, death (1) is followed by burial in sediments (2), keeping the skeleton from being dismembered by scavengers or broken apart by currents.

Some people may not understand what continental drift ... At a divergent boundary where two plates separate and move apart from one another. Magma rises, cools, and creates new crust. 5. What does the discovery of similar fossils on different continents provide evidence of? Continental Drift. The continents were once together and have moved away from each other. 6. Tharp’s maps, however, were one of the critical pieces of evidence for what became known as Plate Tectonics, the theory that built upon and supplanted Continental Drift. Data poured in from... Prediction two: If the islands are of different age than coral reefs will be of different thickness.

Although the notion that continents drift was first suggested as far He expanded on his ideas in his 1915 book, The Origin of Continents and Oceans. Fossil evidence of intermediates remains sparse, but is consistent with the family tree that scientists have...Evidence of six mass extinctions can be seen in the fossil record. There are two primary events that are believed to have contributed to these mass extinctions. The movement of the Earth's surface via continental drift is one such event. Plate tectonics provides the explanation for why continental drift occurs. Evidence for continental drift can also be found in fossils and rocks. For example, similar fossils have been found along the matching coastlines of South America and Africa. The organisms that formed these fossils could not have traveled across the Atlantic Ocean. Therefore, the two continents must once have been joined together. Wegener's theory of continental drift.

Evidence for continental drift Matching coal beds, mountains, and fossils Wegener was not the only scientist to suggest that continents moved. But his theory stood out because of the evidence that he gathered to support his idea of continental drift. Wegener’s evidence is presented in the graphic below and listed at the right in the sidebar. The continental drift controversy has been deeply analysed in terms of rationalist notions, which seem to find there a unique topic to describe the weight of evidence for reaching consensus. In this article I analyse continental drift debates from a different perspective which is based on styles of thought.Fossil evidence supporting continental drift. A. Fossils of Mesosaurus are found only in nonmarine deposits in eastern South America and western Africa. Mesosaurus was a freshwater reptile incapable of swimming the 5,000 kilometers of open ocean that now separate these continents.Evidence for continental drift can also be found in fossils and rocks. For example, similar fossils have been found along the matching coastlines of South America and Africa. The organisms that formed these fossils could not have traveled across the Atlantic Ocean. Therefore, the two continents must once have been joined together. pieces of evidence which also confirm it), there are interesting and important differences among the ways in which theories are confirmed by evidence. Thus, a given piece of evidence might lend support to a theory directly (as when the theory provides a particularly good explanation of that piece of evidence), or more indirectly, by, e.g.,

This is because species (particularly animals and plants living on land) could not have ‘spread’ over the wide oceans. In the year 1912, Wegener made the proposal that all the continents were previously one large continent, but then broke apart, and had drifted through the ocean floor to where they are now located. Apart from using the fit of the two continents already mentioned, Wegener also used fossil distribution and lithological similarity as evidence.

In the example at right, death (1) is followed by burial in sediments (2), keeping the skeleton from being dismembered by scavengers or broken apart by currents. With his death, the Continental Drift Theory was quietly swept under the rug. Why Was Alfred Wegener's Continental Drift Theory Rejected?

His most notable work was the theory of continental drift. Divergent plate boundary is a boundary along which two plates move apart from one another. Convergent plate boundary is a boundary along which two plates come together. 30. How did the presence of Glossopteris fossils support Wegener's idea of continental drift?
