The Plate Tectonic Theory:
The theory that the outer layer of the Earth, the lithosphere, is broken up into dozens of fragments called plates. These plates move around across the Earth's surface.
The plates are grouped as minor plates and major plates, which obviously are the larger tectonic plates.
How many tectonic plates are there on Earth? Include minor plates as well.
The seven major plates are: the African plate, Antarctic plate, Eurasian plate, Indo-Australian plate, North American plate, Pacific plate, and the South American plate.
The remaining minor plates are: the Arabian Plate, Caribbean Plate, Juan de Fuca Plate, Cocos Plate, Nazca Plate, Philippine Sea Plate, and the Scotia Plate.
