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 refers to the movement of the continents relative to each other. Polar wandering (similar to Continental Drift Theory) Polar wandering is the relative movement of the earth's crust and upper mantle with respect to the rotational poles of the earth Continental Drift theory was put forth by Alfred Wegener, a German meteorologist, polar explorer, astronomer, and geologist. He is in fact known as the father of continental drift. In a lecture in 1912, Wegener proposed a startling theory of 'continental drift'. Continental Drift Theory (Alfred Wegener The continental drift theory hypothesised the distribution of the oceans and continents on Earth surface. The idea of lateral movement of continents or continental drift was put forward in 1912 by Alfred Wegener in his book The Origin of Continents and Oceans

ZIMSEC O Level Geography Notes: The theory of continental drift The theory of or idea that present day continents were once one single continent. Continental drifts refers to the movement of continents. The theory says that continents have been moving for millions of years and still do so today The concept of Taylor, thus, is considered to be first at­tempt in the field of continental drift though Antonio Snider presented his views about 'drift' in the year 1858 in France. Main purpose behind the postulation of 'drift hypothesis' of Snider was to explain the simi­larity of the fossils of the coal seams of carboniferous period in North America and Europe 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. The speculation that continents might have 'drifted' was first put forward by Abraham Ortelius in 1596. The concept was independently and more fully developed by Alfred Wegener in 1912, but his hypothesis was rejected by many for lack of any motive mechanism. Arthur Holmes later proposed mantle convection for.

Continental drift theory was proposed by Alfred Wegener in 1912. The theory deals with the distribution of the oceans and the continents. According to Wegener's Continental Drift theory, all the continents were one single continental mass (called a Super Continent) - Pangaea and a Mega Ocean surrounded this supercontinent It was from the continental drift theory, convection current theory and the theory of seafloor spreading, the theory of Plate Tectonics was formulated. In 1967, McKenzie and Parker suggested the theory of plate tectonics. Morgan later outlined the theory in 1968 CONTINENTAL DRIFT AS ALTERNATIVE TO CONTRACTION THEORY In the early 20th century, contraction theory was challenged by three independent lines of evidence. The first came from field mapping. Nine-teenth-century geologists had worked in great detail to determine the structure of mountain belts, particularly the Swiss Alps and the Nort Ans: Continental Drift theory had been proposed by Alfred Wegner in 1912, it talked about distribution of continents and the oceans. According to Wegner all continents used to form a single land mass known as PANGAEA and there was a mega ocean called as PANTHALASSA The continental drift theory is the theory that once all the continents were joined in a super-continent, which scientists call Pangaea. Over a vast period of time, the continents drifted apart to their current locations. Alfred Wegener first supported continental drift. Wegener's explanation of continental drift in 1912 was that drifting occurred because of.

Continental drift During the 20th Century, scientists developed the theory of Plate Tectonics. The theory suggested that the crust of the Earth is split up into seven large plates (see map below) and a few smaller ones, all of which can slowly move around on the Earth's surface

Continental Drift Theory of Taylor Theories - Geography Note

Continental drift is a phenomenon which explains how the earth's continents move on the surface of the ocean bed. Abraham Ortelius was the first geographer who proposed this phenomenon in 1596. The theory was independently developed in 1912 by Alfred Wegener, but it was rejected due to lack of mechanism (which was introduced by Arthur Holmes) Despite a large body of compelling fossil and rock evidence, his theory was rejected by most other scientists. He could not explain how the continents moved. It was only in the1960s that the Continental Drift Theory finally became accepted and became part of the Theory of Plate Tectonics. Continental Drift .

Staple notes on page 5 Chapter 7 Notes : Mountain Building Once the idea of continental drift took hold in the early part of the 20th century, Significant opposition to the drift theory continued until as late as the 1960's when Holmes's idea of convection finally took hold following the advent of plate tectonics. 4

Continental drift referred to the present of the continent on a vast scale. F. B. Taylor who propounded the continental drift theory incorporating much other geological evidences but in 1910 and 1912 Alfred Wegener, a German Meteorologist, advocated that continents had drifted apart and suggested mechanism why which this might have occurred.; Wagner's theory of continental drift was. continental drift theory had a large number of adepts. Before 1961, only 22% of profes‑ sional geologists surveyed accepted the continental drift theory; by 1977 that percentag It was then that the idea of continental drift began to take shape as he collected more corroborating and similar evidences. He later recalled, a conviction of the fundamental soundness of the idea took root in my mind. In 1912, at the age of 31, Wegener published two articles in which he hypothesized the theory of continental drift Advocates of the theory affirm its ability to explain puzzling problems of tectonics, ice ages, animal and plant migration, and palaeomagnetism. However, while the hypothesis of continental drift is supposed to solve many problems connected with the surface of the earth, it also raises substantial questions about the upper mantle

  2. The continental drift theory is one of the primary methods used to promote an old earth. This theory goes something like this : Since it appears that the East coasts of North and South America would fit together with the coasts of Africa and Europe, perhaps they once did
  3. OVERVIEWContinental drift, in the context of the modern theory of plate tectonics, is explained by the movement of lithospheric plates over the asthenosphere (the molten, ductile, upper portion of the Earth's mantle). Precisely used, the term continental drift is actually rooted in antiquated concepts regarding the structure of the Earth
  4. g for his theory of continental drift, it was not until the 1960s, when additional field evidence was analyzed, that the theory of plate tectonics (the modern version of continental drift theory) was widely accepted
  5. Seafloor spreading helps explain continental drift in the theory of plate tectonics. When oceanic plates diverge, tensional stress causes fractures to occur in the lithosphere. At a spreading center, basaltic magma rises up the fractures and cools on the ocean floor to form new seabed

Tharp's steadfast determination had paved the way for Wegener's continental drift theory to gain traction.
