Yes, the Earth's surface is divided into more than 50 large and small tectonic plates. The number is not fixed, as some plates are very small and scientists are still refining their understanding of the boundaries between them.

While there are a few major plates that are well-known (like the Pacific, North American, and Eurasian plates), there are many others that are smaller and less obvious. These smaller plates can be significant for understanding geological events like earthquakes and volcanic activity.
