Difference Between Continental Drift and Plate Tectonics Therefore, based on the concepts of the continental drift and other developing ideas at the time, a general theory was developed, which is now known as the plate tectonics. Plate Tectonics. Plate tectonics is the theory explaining the motion of the outer crust or the lithosphere of earth. Lithosphere is divided into tectonics plates. Two main types of tectonics plates are the oceanic crust and continental crust. Oceanic crust is mainly composed of Silicon and magnesium, hence called SIMA.

- Theory of the formation and movement of the plates that cover the Earth's surface. Continental Drift The theory that all continents are fragments of Pangaea now drifting apart.

- Subduction is the process that destroys oceanic crust, and sea-floor spreading is the process that creates oceanic crust. Sea-floor spreading is driven by crust formation along the mid-ocean ridges, meandering undersea mountain ranges that span Earth like the seams of a baseball.eafloor spreading Theory that explains how continental drift occurs. It proposes that the ocean floor is moved laterally as new basalt rock is injected along mid-ocean ridges, and so the ocean floor becomes older with increasing distance from the ridge. See also plate tectonics.

2 why was the continental drift hypothesis proposed 5. Plate tectonic theory builds on the continental drift hypothesis and the theory of seafloor spreading. As such, it is a unifying theory of geology. Explain why it is a unifying theory. ANSWER: Plate tectonic theory ties together observations used to support continental drift with the driving mechanism from seafloor spreading and with other seemingly unrelated data and observations, such as paloemagnetism and the occurrence of earthquakes and volcanism.

Plate tectonics Plate tectonics is a theory of geology. It has been developed to explain large scale motions of the Earth 's lithosphere. This theory builds on older ideas of continental drift and seafloor spreading. Dissipation of heat from the mantle is the original source of energy driving plate tectonics. Exactly how this works is still a matter of debate. The driving forces of plate motion continue to be active subjects of on-going research.

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. second problem was that Wegener's estimate of the velocity of continental motion, 250 cm/year, was implausibly high. (The currently accepted rate for the separation of the Americas from Europe and Africa is about 2.5 cm/year). And it did not help that Wegener was not a geologist.

What Is the Theory of Continental Drift? A: The theory of plate tectonics, formerly known as continental drift, is a working model that describes the movement of the continents and sea floor across the surface of the Earth. The theory explains many anomalous facts about Earth's geology, such as the present arrangement of landmasses.

Continental Drift: Theory & Definition Magnetic minerals aligned in ancient rocks on continents also showed that the continents have shifted relative to one another. The theory of continental drift reconciled similar fossil plants and animals now found on widely separated continents. Gondwana is shown here.late tectonics is the widely accepted theory that Earth's crust is fractured into rigid, moving plates. In the 1950s and 1960s, scientists discovered the plate edges through magnetic surveys of the ocean floor and through the seismic listening networks built to monitor nuclear testing.

What are some similarities between the theory of continental drift and plate tectonics? Continental drift is the theory that continents have moved, relative to each other, moving apart or together, during the history of the earth.

- The theory of plate tectonics states that the plates of the earth move due to convection in the mantle. This is what brings continents together and apart. Plate Tectonics stat…es that Earth's crust and the outermost part of the mantle are mechanically connected to each other.

What is the importance of continental drift? Continental drift refers to the movement of the Earth's continents relative to each other. The theory was first proposed by Frank Bursley Taylor in 1908, at a meeting of the …Geological Society of America.

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.late tectonics is the widely accepted theory that Earth's crust is fractured into rigid, moving plates. In the 1950s and 1960s, scientists discovered the plate edges through magnetic surveys of the ocean floor and through the seismic listening networks built to monitor nuclear testing.

- But plate tectonics is the theory which suggests that the Earth's crust is made up of solid plates moving relative to each other. Plate tectonics and the plate tectonics theor … y aren't really two separate things. However plates are pieces of the Earth's crust which are moving.

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.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.

Plate tectonics Plate tectonics is the geologic theory that Earth's crust is made up of rigid plates that float on the surface of the planet. Tectonics comes from the Greek word meaning builder. The movement of the plates toward or away from each other either directly or indirectly creates the major geologic features at Earth's surface. Plate tectonics revolutionized the way geologists view Earth. Like the theory of evolution in biology, plate tectonics is the unifying concept of geology.

difference between continental drift and plate tectonics Plate Tectonics is a theory of global tectonics in which the lithosphere is divided into a number of crustal plates, each of which moves on the asthenosphere. Continental Drift, however, is a theory developed by Alfred Wager who suggested that in the past, there was a super continent called 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.

plate tectonics The theory, or idea, of plate tectonics says that Earth's outer layer is made up of large, moving pieces called plates. All of Earth's land and water sit on these plates. The plates are made of solid rock. Under the plates is a weaker layer of partially melted rock. The plates are constantly moving over this weaker layer.

Plate Tectonics Plate Tectonics. Plate Tectonics is a geologic theory explaining the movements and forces in the Earth crust. It was developed during the mid 20th century, but the basic ideas were first put into words by the German geologist Alfred Wegener during the 1920s.
