Detailed explanation-1: -There are 7 primary plates (Pacific, North America, Eurasia, Africa, Indo-Australian, Antarctica, and South America) that make up the majority of the earth’s surface and the Pacific Ocean. Then there are secondary plates such as the Caribbean, the Cocos, the Juan de Fuca, the Nazca, the Philippines Sea, and the Scotia.

Detailed explanation-2: -There are major, minor and micro tectonic plates. There are seven major plates: African, Antarctic, Eurasian, Indo-Australian, North American, Pacific and South American. The Hawaiian Islands were created by the Pacific Plate, which is the world’s largest plate at 39, 768, 522 square miles.

Detailed explanation-3: -The earth is considered to have 15 major tectonic plates. Seven of which are primary plates and the rest are secondary plates. The primary plates are the African plate, the Antarctic plate, the Eurasian plate, the Indo-Australian plate, the North American plate, the Pacific plate, and the South American plate.

Detailed explanation-4: -There are two kinds of plates – oceanic and continental plates. When oceanic and continental plates meet, the denser oceanic plate moves under the less dense continental plate. The Australian plate is a continental plate and the Pacific plate is an oceanic plate.

Detailed explanation-5: -These divisions are inevitably somewhat arbitrary, but by convention we recognise seven main or “primary” tectonic plates: these are the African Plate: Antarctic Plate, Eurasian Plate, Indo-Australian Plate, North American Plate, Pacific Plate, and South American Plate.
