Continental drift is the theory, originating in the early 20th century, that Earth's continents move or drift relative to each other over geologic time. [1] The theory of continental drift has since been validated and incorporated into the science of plate tectonics, which studies the movement of the continents as they ride on plates of the Earth's lithosphere.
The evolution of tectonophysics is closely linked to the history of the continental drift and plate tectonics hypotheses. The continental drift/ Airy-Heiskanen isostasy hypothesis had many flaws and scarce data. The fixist/ Pratt-Hayford isostasy, the contracting Earth and the expanding Earth concepts had many flaws as well.
Continental Drift is a 1985 novel by Russell Banks.Set in the early 1980s, it follows two plots, through which Banks explores the relationship between apparently distant people drawn together in the world under globalization, which Banks compares to the geologic phenomenon of continental drift.
The Wilson cycle theory is based upon the idea of an ongoing cycle of ocean closure, continental collision, and a formation of new ocean on the former suture zone.The Wilson Cycle can be described in six phases of tectonic plate motion: the separation of a continent (continental rift), formation of a young ocean at the seafloor, formation of ocean basins during continental drift, initiation of ...
Continental drift is the theory which emerged in the early 20th century that the Earth's continents have moved over geologic time relative to each other, thus appearing to have "drifted" across the ocean bed. [2] The idea of continental drift was subsumed by the theory of plate tectonics in the mid-20th century.
While his ideas attracted a few early supporters such as Alexander Du Toit from South Africa, Arthur Holmes in England [27] and Milutin Milanković in Serbia, for whom continental drift theory was the premise for investigating polar wandering, [28] [29] the hypothesis was initially met with scepticism from geologists, who viewed Wegener as an ...
The Vine–Matthews–Morley hypothesis, also known as the Morley–Vine–Matthews hypothesis, was the first key scientific test of the seafloor spreading theory of continental drift and plate tectonics. Its key impact was that it allowed the rates of plate motions at mid-ocean ridges to be computed.
According to Daly's biographer, James Natland, Daly was an early proponent of Arthur Holmes and Alfred Wegener's continental drift theory. [5] Daly summarized his ideas in his 1926 book, Our Mobile Earth, which included on the title page small print adopted from Galileo: E pur si muove. Daly's theory on continental displacement was based partly ...
