What caused continental drift? Continental drift takes place because continents sit on crustal plates which float on the Earth's magma, and the magma has convection currents in it which push against the plates and cause them to move, slowly but inexorably.

Continental Drift Continental Drift is the theory describing the movement of the continents that is the result of plates in the Earth's crust that move. Continental Drift is the theory describing the movement of the continents that is result of plates in the Earth’s crust that move. The movement of these plates is known as plate tecktonics.

Seafloor spreading Age of oceanic crust; youngest (red) is along spreading centers. Seafloor spreading is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge.Seafloor spreading helps explain continental drift in the theory of plate tectonics.arlier theories (e.g. by Alfred Wegener and Alexander du Toit) of continental drift were that continents ploughed through the sea. The idea that the seafloor itself moves (and carries the continents with it) as it expands from a central axis was proposed by Harry Hess from Princeton University in the 1960s.

Continental drift Continental drift is the movement of the Earth's continents relative to each other, thus appearing to drift 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 theory was rejected by some for lack of a mechanism. The idea of continental drift has been subsumed by the theory of plate tectonics, which explains how the continents move.

- CONTINENTAL DRIFT. Go to an interactive plate tectonics puzzle. Go to a printable quiz on continental drift. In 1915, the German geologist and meteorologist Alfred Wegener first proposed the theory of continental drift, which states that parts of the Earth's crust slowly drift atop a liquid core. The fossil record supports and gives credence to the theories of continental drift and plate tectonics.

Continental Drift: Theory & Definition Evidence for continental drift. A map of the continents inspired Wegener's quest to explain Earth's geologic history. Trained as a meteorologist, he was intrigued by the interlocking fit of Africa's and South America's shorelines.et 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.

Continental drift The theory of continental drift was not accepted for many years. One problem was that a plausible driving force was missing. A second problem was that Wegener's estimate of the velocity of continental motion, 250 cm/year, was implausibly high.idespread distribution of Permo-Carboniferous glacial sediments in South America, Africa, Madagascar, Arabia, India, Antarctica and Australia was one of the major pieces of evidence for the theory of continental drift.

Seafloor spreading Age of oceanic crust: youngest (red) is along spreading centres. Seafloor spreading happens at the bottom of an ocean as tectonic plates move apart. The seafloor moves and carries continents with it. At ridges in the middle of oceans, new oceanic crust is created. At the Mid-Atlantic Ridge (and other places), material from the upper mantle rises through the faults between oceanic plates. It forms new crust as the plates move away from each other. The new crust then slowly moves away from the ridge. Seafloor spreading helps explain continental drift in plate tectonics. Earlier theories (e.g. by Alfred Wegener) of continental drift were that continents 'plowed' through the ocean.

Science This causes pieces of the continental crust to crack and pull apart. Some slabs of the crust sink, causing a rift zone. If the lithosphere continues to spread, a narrow sea can form. Continued spreading produces an ocean basin and ridge system.

Continental Rifting Figure 5: a) Plate divergence sometimes pulls a continent apart. b) The upper part of the plate is cold and brittle. It breaks along normal faults (the blocks fall down), causing earthquakes and blocks of mountains ranges separated by rift valleys.

- Sea-floor spreading occurs at the mid ocean ridge where new oceanic  crust is formed; continental drift causes sea floor spreading.19 people found this useful.preading of seafloor occurs at the mid-ocean rifts, where there is a continuous flow of material rising from the mantle. There is not a unanimously accepted theory as to the … cause of the rifting that is taking place.

- We are not sure when this process began. Continental drift squashes and changes the continents so much that it is very hard to work out their early history. Continental drift is still happening today and is important because it causes volcanic eruptions, earthquakes and tsunamis. Some people also think that it is one cause of ice ages. Today the theory of plate tectonics, which includes continental drift, forms a framework for the study of geology and the Earth. For the evidence that continental drift is happening, click here.

- The two aspects of Weneger's continental drift hypothesis were objectionable to most Earth Scientist were.

What is Continental Drift Theory? 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 the earth’s rotation. This explanation and his theory were not widely accepted.d. Continental drift theory also gained in popularity because of the theory of plate tectonics. Briefly, plate tectonics suggests that the ocean floor began to spread and that the continents existed on “plates” that moved in response to the changing ocean floor.

- The theory of continental drift simply stated that continents drifted from one location to another over time. Wegener noticed that the coasts of South America and Africa seemed to fit together like a puzzle. Upon further investigation he noticed the following clues that he used to support his hypothesis.
