'pertaining to building') is a scientific theory describing the large-scale motion of seven large plates and the movements of a larger number of smaller plates of the Earth's lithosphere, since tectonic processes began on Earth between 3.3 and 3.5 billion years ago. An exception to this includes Hawaii, which is found in the middle of the Pacific plate over a hot spot. Oceanic islands are also formed when tectonic plates rift apart from each other. Relevance.

There are seven primary tectonic plates in the world, but there are also seven secondary plates and sixty tertiary plates, for a grand total of more than seventy tectonic plates. Other articles where Oceanic plate is discussed: metamorphic rock: Regional metamorphism: In areas of collision between oceanic and continental lithospheric plates such as the circum-Pacific region, the denser oceanic plate is subducted (carried into Earth’s mantle) beneath the more buoyant continental lithosphere (see plate tectonics). A well-known terrestrial example is the San Andreas Fault, which, during the San Francisco earthquake of 1906, had a maximum movement of 6 metres (20 feet). There are also many broad zones of deformation. Scientists have named the largest plates for the continents and oceans they contain. The seven largest plates are the North American Plate, Eurasian Plate, African Plate, Antarctic Plate, South American Plate, Indo-Australian Plate and the Pacific Plate. Oceanic plates are formed by divergent plate boundaries. Most plates are a combination of the two.
