- continental drift definition. A term, no longer used by geologists, that refers to the fact that continents are not stationary, but move across the Earth's surface. Continental drift is one feature of the modern theory of plate tectonics. (See Pangaea.)

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.

Alfred Wegener The British geologist Arthur Holmes championed the theory of continental drift at a time when it was deeply unfashionable. He proposed in 1931 that the Earth's mantle contained convection cells that dissipated radioactive heat and moved the crust at the surface.

Continental Drift Theory and Plate Tectonic Theory These pieces slowly assumed their present positions as the continents. PLATE TECTONIC THEORY. Plate tectonics is the theory that the outer rigid layer of the earth (the lithosphere) is divided into a couple of dozen plates that move around across the earth's surface relative to each other, like slabs of ice on a lake. There are seven or eight major plates and many minor plates.

Seafloor spreading Earlier 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.

Origins of Plate Tectonic Theory To explain these data, Wegener proposed the theory of continental drift in his book The Origins of the Continents and the Oceans, published in German in 1915 and in English in 1924 (Wegener, 1924).

- There is also. a remarkable jigsaw puzzle fit between many of the. southern continents which Wegener noticed and so. proposed the then radical theory of continental drift. This theory was discredited for decades by geologists. until the 1960s but is now widely accepted as the theory. of plate tectonics.

The speculation that continents might have 'drifted' was first put forward by Abraham Ortelius in 1596.he 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.

Continental Drift: Theory & Definition 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.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.
