Question map
Which one of the following is not a minor plate?
Explanation
Tectonic plates are categorized into major and minor plates based on their size and geographical significance. Major plates comprise the bulk of the continents and the Pacific Ocean. According to standard geological classifications, the Antarctic Plate is one of the seven major tectonic plates, covering approximately 60,900,000 km² [3]. In contrast, the Cocos Plate, Nazca Plate, and Caroline Plate are classified as minor plates [3]. Specifically, the Cocos Plate is located between Central America and the Pacific Plate, the Nazca Plate lies between South America and the Pacific Plate, and the Caroline Plate is situated north of New Guinea [3]. While some sources may list the Nazca Plate as a larger secondary plate due to its size (approx. 15.6 million km²), it is consistently distinguished from the primary major plates like the Antarctic, Pacific, and Eurasian plates [3].
