Unveiling the Secrets of Tectonic Plates: A Comprehensive Overview

Tectonic plates are the outermost layer of the Earth's crust, floating on the weaker asthenosphere below, allowing them to move. There are seven major plates, including the Pacific Plate, and at least five minor plates, such as the Philippine Sea and Cocos plates. However, some geologists argue that there are more minor plates, bringing the total to 15. Additionally, there are microplates formed at major plate boundaries, but their number is difficult to define. The total number of tectonic plates may change as scientists continue to study and define them.
