Passage Three The theory of plate tectonics describes the motions of the lithosphere, the comparatively rigid outer layer of the Earth that includes all the crust and part of the underlying mantle. The lithosphere is divided into a few dozen plates of various sizes and shapes, in general the ...
According to this theory, Earth’s surface consists of a number of rocky tectonic plates. The plates fit together at their edges but are not attached to each other. The part of plates that make up the seafloor is called oceanic crust. The continents are just the parts of tectonic plates ...
Learn the definition of a scientific theory. This lesson will explain the characteristics of a scientific theory and the importance of the scientific method. Related to this Question What is plate tectonic theory? Explain the types of plate boundaries, and explain one example for each type of pla...

The Theory of Plate Tectonics The idea that continents moved during the past goes back to the time when people first noticed that the margins of eastern South America and western Africa looked as if they fit together. Geologists also noticed that similar
The studies of continental deep subduction and ultrahigh-pressure metamorphism have not only pro-moted the development of solid earth science in China, but also provided an excellent opportunity to advance the plate tectonics theory. In view of the nature of subducted crust, two types of ...
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...
Mantle convection is the most widely studied method of tectonic plate movement and it is very similar to the theory developed by Holmes in 1929. There are large convection currents of molten material in the Earth's upper mantle. As these currents transmit energy to the Earth's asthenosphere (...
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...
He then compares the earthquake explanations of the plate tectonic theory and the hydroplate theory, and explains why there will be powerful global earthquakes. Origin of Earth’s Radioactivity Bryan Nickel has produced an outstanding 35-minute video presentation of this chapter at www.youtube....
