CONTINENTAL DRIFT : • is the movement of the earths continents relative to each other by appearing to drift across the ocean bed . • Evidence : Evidence for the movement of continents on tectonic plates is now extensive similar plant and animal fossils are found around different continent shores and may once have been joined together • Problems with theory : one problem was that plausible driving force was missing and it didn’t help that wegner wasn’t a geologist. May 18, 2008 · The continental drift theory only exists because South America and Africa appear to fit fairly well to the naked eye. What they don't tell you is that they have to shrink Africa by 40% when they... CONTINENTAL DRIFT THEORY Continental drift is the hypothesis that all the continents had once been joined together in a single landmass. Alfred Wegener named this supercontinent Pangaea. Pangaea existed about 300 million years ago. This was the time when reptiles and winged insects first appeared. Continental Drift theory - Mr. Pezzuto's Science Classes Jan 04, 1999 · In the early twentieth century, American earth scientists were united in their opposition to the new--and highly radical--notion of continental drift, even going so far as to label the theory "unscientific." Some fifty years later, however, continental drift was heralded as a major scientific breakthrough and today it is accepted as scientific ... Twenty years ago geologists were certain that the data correlated perfectly with the then-reigning model of stationary continents. The handful of geologists who promoted the notion of continental drift were accused of indulging in pseudoscientific fancy. Today, the opinion is reversed. The theory of moving continents is now the ruling paradigm and those who question it are often referred to as ... Oct 09, 2017 · The most important thing is to not stop questioning. - Albert Einstein ... and discussed evidence for the Theory of Continental Drift. 0 Comments Leave a Reply ...

This is important for the reasons stated in the next paragraph, and it's odd (at least) that Attenborough conflated the two as they are two very different things. So the history of Wegener's exposition of the theory of continental drift is anything but a palliative for supporters of the AAT/H.

Harold Hess was a scientist/marine who discovered the theory of sea floor spreading which was able to explain continental drift. He discovered the mid oceanic ridge aswell. Describe the observations and evidence used by Harry Hess to explain the unusual topography of the ocean floor in his report: “The history of the ocean basins”.

Wegener first presented his idea of continental drift in 1912, but it was widely ridiculed and soon, mostly, forgotten. Wegener never lived to see his theory accepted—he died at the age of 50 while on an expedition in Greenland. Only decades later, in the 1960s, did the idea of continental drift resurface.

Continental drift, large-scale horizontal movements of continents relative to one another and to the ocean basins during one or more episodes of geologic time. This concept was an important precursor to the development of the theory of plate tectonics, which incorporates it. Read More on This Topic

May 06, 2016 · Continental drift created biologically diverse coral reefs Date: May 6, 2016 Source: ETH Zurich Summary: An international research team has studied the geographical pattern of the evolution of ... Continental drift was hotly debated off and on for decades following Wegener's death before it was largely dismissed as being eccentric, preposterous, and improbable. However, beginning in the 1950s, a wealth of new evidence emerged to revive the debate about Wegener's provocative ideas and their implications. Wegener attempted to explain how continental drift took place. He suggested that the continents plowed across the ocean floors. Unfortunately, Wegener could not provide a satisfactory explanation for the force that pushes or pulls the continents. Because Wegener could not identify the cause of continental drift, most geologists rejected his idea. Figure 13 Alfred Wegener Although scientists rejected his theory, Wegener continued to collect evidence on continental drift and to update his book. We are told that continental drift was just a precursor to the far more advanced theory of plate tectonics.

May 24, 2010 · Continental Drift is the principle that the continent landmasses have not remained in fixed positions, but have moved around the earth's surface apparently independently. It is important in evolution because of the effects it has had on evolution and taxonomic diversity, brought about by the collision and moving apart of landmasses.

Sep 29, 2011 · The theory of continental drift andformationof mountains gradually emerged from a mosaic of observa- tions that were not easy to explain using simple stratigraphy rules, and which therefore made it necessary to find models that equally fulfill the basic logical requirements of Steno's stratigraphy laws and adequately explained the observed features.

continental drift on firm scientific footing. Theory of Continental Drift In a lecture delivered at the annual meeting of the Geological Association in Frankfurt on January 6, 1912, Wegener rejected the unrealistic concept of sunken land bridges, and expounded the new theory of continental drift. He realized that apparently

Sep 11, 2020 · Indeed, some fragments of continental crust have been discovered that are more than 4 billion years old— nearly nine-tenths of the age of Earth! So, as it turns out, Alfred Wegener was wrong about one important detail in his theory of continental drift: It is not just the continents that are drifting.
