The correct answer is D. Antarctica is considered a major tectonic plate, while Nazca, Arabia, and Philippines (Philippine Sea Plate) are generally classified as minor tectonic plates.
The Earth’s lithosphere is broken into several large plates (major plates) and many smaller ones (minor plates) that float on the asthenosphere. There are typically identified as 7 major plates: African, Antarctic, Eurasian, Indo-Australian, North American, Pacific, and South American plates. Minor plates include the Arabian Plate, Caribbean Plate, Cocos Plate, Juan de Fuca Plate, Nazca Plate, Philippine Sea Plate, Scotia Plate, etc.
Major plates are the largest rigid slabs of the lithosphere. Minor plates are smaller sections, often situated between major plates or in complex tectonic regions. The interaction between these plates at their boundaries is the cause of most seismic and volcanic activity on Earth. The Antarctica plate covers the continent of Antarctica and surrounding oceans and is a significant part of the global plate system.
