Related to Plate tectonic:plate tectonic theory plate tectonics n. 1.(used with a sing. verb)A theory that explains the global distribution of geological phenomena such as seismicity, volcanism, continental drift, and mountain building in terms of the formation, destruction, movement, and interactio...
An essential part of the tectonic plate explanation of continental drift is the idea that molten rock from the mantle is forced up through the seafloor at mid-ocean mountain ridges where two plates meet. This molten material adds new oceanic crust to the plates on either side of the ridge. ...
Theory of Continental Drift Proposed by Alfred Wegener in 1912. Basic belief that all of the continents were once joined together in a ‘supercontinent’. Met much resistance because Wegener did not have a good model to explain how the continents moved apart. Although the theory was discarded, ...
Wegener's idea of continental drift explained several features of today's continents, but its mechanism was not understood until the theory of plate tectonics was developed. B The tectonic plates move because the oceanic crust of each plate is continuously created on one edge and destroyed on the...
Plate Tectonics Plate tectonics theory explains the global distribution of mountains, earthquakes, volcanoes, ocean basins and rift valleys on the surface of the Earth. What is the theory of plate tectonics? Plate tectonics theory explains that several plates move on top of the soft mantle. Scienti...

subduction or uplift—are simulated by the combined plate tectonic–palaeoelevation model, and constrain the time that seafloor habitats have to accumulate diversity. The model assumes non-selective extinction during mass extinction events (that is, the field of bullets model of extinction; everything...
a geophysicist by the name of Wilson came up with the hot spot theory … to explain how this particular type of volcanic activity can occur—and can go on for maybe tens or even hundreds of millions of years.Wilson’s theory was that hot spots exist below tectonic plates and they’re th...
These interactions are constantly shaping the face of the planet, signified by the term "tectonics" from the Greek word meaning "to build." The results of plate-tectonic forces are most evident at plate boundaries--narrow zones between plates. At divergent boundaries, plates pull away from each...
Wilson's theory was that: hot spots exist below tectonic plates, and they're the cause of these volcanoes. But what causes the hot spots? Hmm, well, the most popular theory that's been proposed is the plume hypothesis. According to this hypothesis, plumes, uh, basically columns of extreme...
