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…
The theory of plate tectonics rests essentially on paleomagnetism data and on the results of submarine cores which are evidence of continuous sea-floor spreading. Each oceanic plate is connected to the adjacent continent. Its continuous movement (a few centimeters per year) accounts for the ...
During the 1950s and 1960s, new data emerged that enabled geologists to propose a mechanism of continental drift. 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...
Great Rift Valley in East Africa A Theory of Plate Motion Wilson combined the thoughts of sea-floor spreading, Earth’s plates, and continental drift into a theory. A scientific theory is a well-tested concept that explains a wide range of observations. Plate tectonics is the geological theory...
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...
The theory of plate tectonics states that Earth’s outer shell is divided into plates. The crust and upper mantle is broken into plates that move around on the mantle, changing in size throughout time. The lithosphere makes up the crust and upper mantle and the asthenosphere a plastic like ...

This lesson provides a definition of plate tectonics, explains the theory of plate tectonics, and what phenomena in the natural world that the theory explains. Related to this Question What drives tectonic plate movement? How do plate tectonics cause major geological events?
The theory of plate tectonics states that pieces of Earth's crust, known as plates, are constantly moving due to the movement in the mantle. This theory explains various geological phenomena such as earthquakes, volcanic activity, and the formation of mountain ranges. It suggests that the Earth...
