Plate tectonics was founded in the late 1960s, and it concerns the distribution and movements of plates, the uppermost layer of the Earth. Plate movements not only control the distributions of earthquakes, volcanoes, and mineral resources in the crust, but also affect the ocean and atmospheric circulations above the crust. Therefore, plate tectonics has been regarded as the fundamental unifying paradigm for understanding the history of Earth.
