The Earth’s lithosphere is divided into several large and small tectonic plates. Major plates are generally considered the largest ones. The seven widely recognized major plates are: Pacific, North American, Eurasian, African, Antarctic, Indo-Australian (or Australian and Indian), and South American. The Saudi Arabian plate is considered a minor plate that is separating from the African plate.

– There are generally considered to be seven major tectonic plates.
– The options B, C, and D (Antarctic, India-Australia-New Zealand/Indo-Australian, Pacific) are all classified as major plates.
– The Saudi Arabian plate is classified as a minor plate.

Besides the seven major plates, there are numerous minor plates (e.g., Arabian, Caribbean, Nazca, Scotia, Philippine Sea) and microplates. Plate tectonics is the theory explaining the movement of these plates and the resulting geological activity.
