Definition Of Continental Drift Theory

Continental drift theory definition- The continental drift is the hypothesis that the continents of the earth have moved away from each other over the geological period. Alfred Wegener named this supercontinent Pangaea.

Continental Drift Simple English Wikipedia The Free Encyclopedia

Pangaea existed about 300 million years ago.

Definition of continental drift theory. This concept was an important precursor to the development of the theory of plate tectonics which incorporates it. Theory of Continental Drift The continental drift hypothesis was developed in the early part of the 20th century mostly by Alfred Wegener. The continental drift theory is the theory that once all the continents were joined in a super-continent which scientists call Pangaea.

Kontinentalverschiebung war eine Theorie die erklärte wie Kontinente ihre Position auf der Erdoberfläche verändern. He called this movement continental drift. Die kontinentale Drift wurde 1912 von Alfred Wegener einem Geophysiker und Meteorologen erklärt weshalb auf verschiedenen Kontinenten gleichartige Tier- und Pflanzenfossilien und ähnliche Gesteinsformationen zu finden sind.

Definition of continental drift. CONTINENTAL DRIFT THEORY Continental drift is the hypothesis that all the continents had once been joined together in a single landmass. Continental Drift Theory CDT Continental drift refers to the movement of the continents relative to each other.

Continental drift - the gradual movement and formation of continents as described by plate tectonics geological phenomenon - a natural phenomenon involving the structure or composition of the earth Based on WordNet 30 Farlex clipart collection. The very slow movement of continents over the earths surface 2. In the early 20th century Wegener published a paper explaining his theory that the continental landmasses were drifting across the Earth sometimes plowing through oceans and into each other.

Seafloor Spreading Theory SFST. Wegener said that continents move around on Earths surface and that they were once joined together as a single supercontinent. Polar wandering similar to Continental Drift Theory Polar wandering is the relative movement of the earths crust and upper mantle with respect to the rotational poles of the earth.

Continental drift was a revolutionary scientific theory developed in the years 1908-1912 by Alfred Wegener 1880-1930 a German meteorologist climatologist and geophysicist that put forth the hypothesis that the continents had all originally been a part of one enormous landmass or supercontinent about 240 million years ago before breaking apart and drifting to their current locations. Over a vast period of time the continents drifted apart to their current locations. 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.

At the time Alfred Wegener was well known for his work in the field of polar meteorology and research but today he is best remembered for his contributions to the development of the continental drift theoryHis first ideas came when he noticed that the Earths continents fitted closely but not along its coasts due to erosion and wear. Continental drift During the 20th Century scientists developed the theory of Plate Tectonics. This theory explained how the continents of the earth change their position on the surface of the earth.

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. The theory of continental drift is most associated with the scientist Alfred Wegener. Continental drift was a theory that explained how continents shift position on Earths surface.

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 Earths surface. A slow movement of the continents on a deep-seated viscous zone within the earth compare plate tectonics. Alfred Wegener first supported continental drift.

This was the time when reptiles and winged insects first appeared. The very slow movement of. 2003-2012 Princeton University Farlex Inc.
